- SEAM INSPECTION FOR LASER BRAZING
At a glance
Seam Inspection for safety-relevant components, e.g. on roof seams, rear trunk lids and water channels of vehicles
Challenge
Automated welding and soldering is essential within industrial production for countless industries. Guaranteeing perfect quality through testing of high volume weld seams and an increasing number of variants require 100% error-free processes. Especially for brazed seams by robots, as there are for too few trained employees available for the visual inspection. Also, the requirements are particularly high when the “just-in-time monitoring systems” have to check the seam sections with traces of powder or smoke.
plasmo’s solution
Quality inspection plays a key role for repeatable and reliable product quality for metalworking manufacturing. To monitor and optimize laser brazing or laser welding seams, the plasmo profileobserver offers the perfect solution. The system recognizes, captures, analyzes and documents the seams as well as geometry and surface. Depending on the manufacturer, fault types and individual tolerances are defined according to internal and external standards. If the profile reading exceeds the specified tolerances, the profileobserver signals that the corresponding assembly (soldered seam) must go to the rework station and the error is displayed directly on the screen.
- Immediate result = no lost time or wasted cost
- Non-destructive
- Efficient
- Unproblematic integration into serial processes
- Features for additional evaluations
- Ease of use
- Flexibility
- Low-maintenance
Result – seam inspection
Through the use of an optical seam inspection system, it is possible to detect existing defects in the seam quickly to minimize cost and optimize the production process. This ensures that only parts with perfect quality are in the downstream production process. Also, all results are documented and stored for the further development and optimization of the soldering process while ensuring guaranteed quality assurance at all times.

Tubes and pipes
- QUALITY ASSURANCE FOR PIPES AND PROFILES
At a glance
Quality assurance for standard and endless pipes, tailored tubes and profiles requires innovative solutions. These can dramatically reduce manufacturing costs and rejects. Everyone knows the negative impact resulting from component failure – expensive production loss, extended downtimes, long inspection intervals or even safety risks are only some examples. In this context, process-monitoring systems can produce technologically relevant highlights.
Challenge
Continuously increasing requirements for quality and economic efficiency challenge customers to optimize products and production processes on an ongoing basis. In view of high productivity and the precision as a tool, these extremely fast processes are becoming constantly more significant in modern manufacturing technology. The implementation of high-tech systems for quality assurance in the production process can result in dramatic savings in weight and costs for simultaneously higher quality standards.
Our customers, for instance in the automotive sector, are among the major innovation drivers and an important sales market for pipes and profile manufacturers. Every vehicle includes many meters of (endless) pipe or pipe-like profiles (tailored tubes), even though invisible. The specifications defined by the EU for a reduction of CO2 emissions have resulted in significant additional challenges for manufacturers and suppliers.
plasmo’s solution
During the welding of pipes and endless profiles, the aspects of ease of welding must additionally be considered. Many issues are relevant, from the design of complex profiles and suitable materials through to the ease of the manufacture. Practical quality assurance is particularly important in this context. In many pipe/profile systems, the weld is no longer visible and any control must be performed inline. In addition, it is crucial that any defects are identified immediately so that the cause can be remedied as quickly as possible. As a result, rejects can be reduced significantly.
的plasmotest sequences are as follows:
- Process visualization: Identifying the potential for production increase and statistical analysis of the processes. In addition, improvement of the process understanding by system operators as well as detection of systematic errors.
- Fault detection through OK/NOK decision: This involves the definition of faults, the elimination of defective parts directly during or after the process. The goal is a 100 percent fatigue-free and objective control of the entire weld.
- Accurate meter-by-meter traceability: Continuous control of interrelations of multiple productions steps ensures subsequent analysis and definition of critical sections.
Selection of the testing equipment
Sensor- and camera-based test procedures as well as ultrasound offer solutions for a wide range of technological challenges for processing speeds of up to 80 -120 m/min, in- and online. From the visualization of the processes and fault detection through to the traceability of components and production steps. Modern online systems are used to ensure early detection of cracks, damage, edge offset, pores or pressure of rollers, etc., that might be produced during the welding process.
Result – quality control
Cracks and damage produced in the welding process are detected early by an online monitoring system and are identified by a time-delayed marking system on the profile or pipe in endless processes. Particularly in the case of stainless steel pipes, these online systems could under certain circumstances reduce the extent of eddy current or radiographic tests, which in some cases are required by law, as rework can be completed beforehand.
An online monitoring system detects cracks and damage from the welding process at an early stage and is characterized by a time-delayed marking system on the profile or pipe during continuous processes. Due to these online systems, the partly legally prescribed tests with eddy current or x-ray can be reduced, especially for stainless steel tubes, since a post-processing can take place first.

Additive Manufacturing
- ADDITIVE MANUFACTURING
At a glance
Engineers have always aspired to design parts without having to take the restrictions of conventional manufacturing methods into account. 3D printing using metals offers new possibilities with high geometric freedom. Even though the market for this manufacturing technology is currently relatively small, this technology is predicted to offer great future potential. Sales of 3D printing systems, the service of these and the respectively required materials are expected to quadruple to € 6.8 billion in the next 10 years.
Challenge
For optimal utilization of the manufacturing process even in safety-critical applications, such as, for example, in medical technology or in astronautics, essential requirements must be fulfilled. These include an understanding of the manufacturing process, the knowledge of the achievable, directional mechanical-technological properties as well as the use of appropriate quality assurance systems. The 3D printing systems for metals currently available in the market are exclusively controlled, resulting in an increasing demand for controlled systems in the industry.
As part of the PAM project, the in-situ process monitoring for injection molding applications was developed, among others, which is a manufacturing process that produces components by horizontally or vertically joining volume elements, mostly in layers. The 3D printing process represents the shortest way for developing a product, from the idea through to market maturity. The process allows for unproblematic manufacture of even the most complicated geometries. Conventional manufacturing methods, such as turning or milling, quickly reach their limits. As a result, there are almost no more restrictions in the design, thanks to which the geometric freedom is among the most important strengths his process has to offer.
The basis for making components from powdered metal are 3D CAD data that are used for generating the physical layers. Following application of a new powdered layer, the metal particles are solidified by application of energy in the form of laser radiation, which produces a locally restricted weld pool.
As presently only controlled systems are available and it is presently not possible to detect the above-described fusion defects in the construction process, the industry has a growing demand for controlled systems. The area of use of metal 3D printing is restricted due to the lack of quality assurance in many industries. Based on the detected fusion defects, a fault pattern could be defined for the quality assurance system to be developed. One approach towards implementing this process monitoring consists in the use of a photodiode-based measuring system that detects the process light produced when melting on the powdered metal. The thus determined measured values together with additional machine parameters represent the basis for monitoring the welding process.
Solution
所有工作相关的实现过程ss monitoring system are carried out on a laser sintering system for EOSINT M 280 type metal parts from the manufacturer EOS. Application of energy is by 200 W ytterbium fiber laser with 1064 nm wavelength. The overall installed size of this system is 250×250×325 mm.
The photodiode-based plasmo fastprocessobserver measuring system is implemented at two different measuring positions. One of the measuring positions is located within the process chamber while the second one is situated outside on the camera adapter of the scanning optic. In the process chamber, the reflected light is captured by four fiber optic cables of a quadruple fiber oriented towards the construction platform. At the camera adapter, the reflections are detected directly in the laser beam path, also by fiber optic cables. The fiber optic cables of both measuring positions ultimately lead to the measuring system comprising the plasmo fastprocessobserver, which converts the optical signals of the fiber optic cables via photodiodes into corresponding electrical signals. These are then recorded via high-speed modules of a data acquisition system. Aside from the process light, this data acquisition system also records other machine data, such as for example the scanner position. One measured data file is produced for each layer and is used as the basis for evaluations.
The recorded process data is evaluated using specifically developed algorithms that include statistical evaluations for every layer. These comprise, for instance, mean value and standard deviation of the reflected radiation, relative distribution of the voltage readings of the process light for a division into voltage ranges, current welding angle, etc.
A CT scan of the samples was produced to assign the recorded process data to the produced component. This shows a significant increase in the number of inclusions in layers exposed to reduced laser output. Based on the evaluation algorithms, in particular the algorithm used for allocating the recorded process light to the corresponding scanner position, this inclusion should then be recovered in the logged process data.
Result
The following procedure was applied to find the imperfections, which were present according to the CT scan, in the recorded process data: As it was not known beforehand what made up the inclusion in the recorded process light at the two measuring positions, the area where the fault could be found had to be restricted first. Owing to the high resolution of the CT scan, the area could be restricted to a few layers having a thickness of 0.03 mm in the direction of the design height. According to the CT scan, the inclusion to be found extended over 6 layers. By investigating the time sequences of the recorded process light, it was eventually possible to detect the air inclusion in 5 layers.
Once the fault had also been identified in the process data, the measured scanner position was used to allocate the time signals locally – referred to as localization – so as to determine its recorded position on the construction platform. This could successfully be done through appropriate parametrization of the algorithm.

- RAIL MEASUREMENTS
At a glance
的plasmorailobserver was developed with various project partners as part of the research cooperation project “plasmaTram”. The defined task was to measure the entire rail network of Vienna tramway with unprecedented accuracy to achieve early detection of any abrasion or defective spots that place high stress on the rails and, time and again, result in interruptions in tramway traffic.
Thanks to a very fast camera technology, the geometry of the rail can be measured with the highest accuracy at a driving speed of 60 km/h.
Challenge
The control of any rail damage requires absolute precision, repeat accuracy and stability. The measurement and evaluation software required for the measurement system was developed. Several criteria had to be fulfilled in the process.
On the one hand, it had to be ensured that the staff driving in the measuring vehicle received live values displayed on the monitor during the measurement travel to be able to detect any significant defects on the rails immediately.
This task required the processing of large data amounts and the calculation of the necessary measured variables in real time. In addition, these data amounts had to be displayed and saved in real time to facilitate subsequent archiving in a maintenance database and availability for further analyses.
Solution
的plasmorailobserver was integrated into the measuring vehicle of Wiener Linien. It was thus possible to test the measuring system repeatedly in the urban environment under real-world conditions and to adapt the thus derived findings and general conditions to achieve the best possible measurement results. A special bracket had to be developed and manufactured for optimal integration of the measuring system in the measuring vehicle. In addition, the entire wiring was integrated and a separate measuring station for the system was created. In order to achieve the required high accuracies, the prototype used lasers operating at a high light energy.
In addition, a special compression algorithm was developed that compressed the data in real-time and without any loss by about 90% to a tenth of its original size and that allowed for efficient access to individual profiles even in ranges of hundreds of gigabytes.
To ensure that the plasmo railobserver met the requirements in the road network, the optical system was designed to withstand the dynamic challenges. In addition, special calibration elements were developed with the goal of achieving an absolute calibration of the measuring system and, in subsequent continuous operation, to provide the operator with the option to check the necessity for re-calibration at periodic intervals. Furthermore, an accurate optical measurement was required to measure and to compare the two rail tracks on an absolute basis. The thus derived measured variables (e.g. track width) were crucial. Thanks to the high resolution of the system, it was discovered in the course of the project that elements left and right of the rail could also be recorded and measured.
Result
The system will provide an even greater benefit in future. In particular, the prototype now permits reliable detection and measurement of rail track structures, such as e.g. switches, switch tongues, crossings, etc. As a next step, continuous monitoring of these elements will in future be automated with unprecedented accuracy. The goal is to utilize the findings gained in this project to contribute towards an automated maintenance schedule and to consider subsequent development steps with regard to potential use in the subway area. The long-term goal is to establish a rail monitoring system for the urban area capable of covering various rail types also at international level. (e.g. grooved and flat-bottom rail).

3D observer
-
- The 3D observer is an optical sensor system capable of fully identifying, capturing and measuring three-dimensional objects and their location in a space (in relative or absolute coordinates). It then supplies these data to a robot or linear axis system, for example, as commonly employed in many automated production processes. The 3D observer provides information regarding the location, the 3D contour or gripping point of objects in the production chain. It is also capable of solving tasks which require the simultaneous use of both 3D and 2D optical technology. The process is flexible, extremly quick and does not depend on the material or the colour and is almost independent from the surface. Thanks to the high processing speed, this unique 3D scanning process allows 100% control of the production process.
