Real-Time Automatic Detecting System and Online Monitoring Software in Mash Seam Welder

With the development of modern industry, welding technology is an indispensable means of industrial technology in mechanical processing industry and plays an important role in national economic construction. Narrow lap welding is the first important process to ensure continuous production in hot dip galvanized steel production lines. Currently., narrow lap welding still depends on manual visual inspection and sampling inspection after welding. We equip 3D laser line scan camera and eddy current testing system to improve reliability and monitoring timeliness in welding process. Gray Image and Height Image of surface appearance, as well as eddy current signal inside weld are collected by our equipment which is following with welding arm. Finally., collected data should be analyzed through software developed by C#. Selecting hardware, data transmission, and developing software is all involved in this program and the detection system has been used in actual production of enterprise as a complete solution.
