(1) Welding Inspection

Quality testing and quality assurance systems for the production of tailor welded blanks to provide a guarantee, the production of tailor welded blanks using automated production line process, to ensure security, economic production, which requires modern detection equipment. As early as 1985, ThyssenKrupp Tailored Blanks Ltd. began producing blanks when the monitoring system has been adopted, and now, this system has been even better. Laser welding seam behind the installation of a monitoring system for monitoring the quality of the weld to ensure the welds meet the quality requirements. Plasma Monitoring System were used to monitor the stability of the  Welding Electrode , computer-aided system to deal with the sensor in the welding process to provide the signal.

Tailored blanks requires economical automatic or semi-automatic production lines, while the use of modern technology to monitor the welding process and product quality. In order to meet any of these new fully automated production process of splicing plate production requirements, Thyssen Welding Technology Co., Ltd., ThyssenKrupp Steel Co., Ltd. research department, ThyssenKrupp Laser Technology Co., Ltd., and Disennuobang Co., Ltd. made in the early stages of weld quality and production process management automatic evaluation of the different possibilities, and began operating the first plant tailored blanks the first one on the use of tailored blanks on the floor in the Audi 100. In recent years, the technology in different stages of development and was further improved, it can not only control the welding process itself, and that under the existing system can be developed to evaluate the latest generation of welding technology. The monitoring system can not only monitor the high-speed welding process weld geometry of defects, but also to detect very small holes.

(2) evaluation system

Thyssen LAM (Laser Applications Management), combined with the weld inspection system can not only identify trends defects, such as irregular geometric gap (the gap incident, edge displacement, root subsidence), but also found a small degree of defects, For example, vents and holes. Light stripes, and the combination of plasma sensor system has been supplemented by the best condition, it can guarantee high measurement rate of the case at high welding speed, secure found slightly flawed possibilities.

A computer-aided assessment system can automatically assess the sensor signals, including during the welding process. Measurement points to determine whether the conditions related to meet specified requirements, or whether the error led to the whereabouts of joint quality has occurred. During the welding process, welding temperature by infrared measurement of registration. The mosaic panels were evaluated any sensor data records are stored in a short protocol, which means that the quality of the product by allowing documents to prove.

A complete error detection system to warn the operator that occur in the automatic welding facilities, all the mechanical defects, the quality management and monitoring system was extended to nonlinear Mig Welding Electrode for the production of a new device concept. Sensors placed in the welded joints can be detected before the sheet is to be welded connection to the edge, not only allows to identify the exact location of the edge connector, and allows measurement of the overlap between the sheet metal. When the identification of overlapping measurements is beyond a predetermined limit, it will warn the operator, and automatically sorting out the gap. In addition, the use of this equipment, connecting the edge of the detection signal is also used to accurately identify and adjust the edge of the laser beam connections.
