摘要：

A new twin-tungsten TIG (T-TIG) welding method was studied. This method differs from the conventional TIG method,it places two electrodes insulated from each other in the same welding torch,and a coupling arc is generated from the two electrodes. The coupling arc pressure was measured and preliminary welding experiment was made. The results show that the coupling arc can keep arc pressure at a low level compared with conventional TIG arc,and welding can be achieved under higher current and high travel speed with sound appearance of weld. Therefore,this new method can applied widely in high efficiency welding.
