一种高能量钨极惰性气体保护焊焊枪
摘要：
一种高能量钨极惰性气体保护焊焊枪，包括外绝缘管、与外绝缘管一端螺纹连接的钨极座及与钨极座螺纹连接的陶瓷喷嘴，在陶瓷喷嘴内设有钨极，钨极安装在钨极座上，外绝缘管的另一端连接接头端，焊枪还具有冷却水系统，所述冷却水系统包括水道，水道一端为接头端的进水端，水道另一端为接头端的出水端，在水道与钨极之间设有控制冷却水水流的密封阀。本焊枪将传统焊枪中的钨极间接式冷却变成了钨极的直接水冷，通过冷却方式的变化提升了钨极截面上的电流密度，进而可利用电弧产生的“自磁收缩”效应获得强且集中的电弧力场和温度场，最终大大增强了电弧的熔透能力。
摘要（英）：

A high-energy welding gun for tungsten inert gas shielded welding comprises an outer insulation tube, a tungsten electrode seat, a ceramic nozzle and a cooling water system, the tungsten electrode seat is in threaded connection with one end of the outer insulation tube, the ceramic nozzle is in threaded connection with the tungsten electrode seat, a tungsten electrode is arranged in the ceramic nozzle and mounted on the tungsten electrode seat, the other end of the outer insulation tube is connected with a connector end, the cooling water system comprises a water channel, one end of the water channel serves as a water inlet end of the connector end while the other end of the water channel serves as a water outlet end of the connector end, and a seal valve for controlling water flow of cooling water is arranged between the water channel and the tungsten electrode. The high-energy welding gun for tungsten inert gas shielded welding has the advantages that indirect tungsten electrode cooling in a traditional welding gun is changed into direct tungsten electrode cooling in the welding gun, electric current density on the cross section of the tungsten electrode is increased by means of change of a cooling mode, an intense and centralized electric arc force field and an intense and centralized temperature field are obtained by a 'magnetic self-pinch' effect produced by electric arcs, and penetration capacity of the electric arcs is enhanced greatly finally.
