| Abstract: | This paper surveys the characteristics, classification and the parameters matching for the technology of keyhole plasma arc welding. Keyhole plasma arc welding can cause a special keyhole, with which welding speed, workpiece thickness and welding efficiency will be all increased significantly. It can be generalized to constant, pulsed, variable polarity and special plasma arc welding, so it can satisfy special requirements of many different industries. This paper is quite significant to guide welding practice and increase productivity and the quality of welding joints. |
