There are over 5,000 resistance spot welds for an automobile body. The structure safety is depended onthe quality of these welds for the automobile body. It has some problems for welding industry due to expulsion,quality inspection, compensation of the weld cap wear and so on. Those problems can be eliminated by intelligent weld controller(IWC). This is a new device for the welding machine to control welding process without expulsion.It can increase welding body strength about 40%and save energy over 50%under a series of welding tests. |
