摘要
根据绳索取芯钻杆焊缝内表面不得有余高的特殊要求,提出了钻杆外等离子弧焊(PAW)和钻杆孔内钨极氩弧焊(TIG)同时进行的PAW-TIG联焊方法.研制的焊接专机可以制造和修复φ53mm～φ108mm的复合式钻杆.可以进行深度为1500mm的超深孔内孔焊.
The particular demand for welding of core drill rod with wire - rope coring is to avoid any reinforcement inside the rod therefore a procedure with plasma arc welding on outside and TIG welding within inside simultaneously is put forward and a special welding machine is developed, too. The machine can be used for fabrication and repair of the compound rod in the range of dia. 53- 108 mm with depth of up to 1500 mm into the rod hole.
