The main method of industrial automated welding is currently the robot-mounted welding torch welding a specific part in a fixed position on a fixed track. If the placement is not standardized it is easy to cause defects such as missed welds, galling, arc pits, and surface porosity. There is very little equipment on the market to monitor the position of the welded part before welding, and by the time personnel notice the problem the part has already been welded and even flows into the next process, causing a significant quality impact.
