摘要
金属镍在电渣精炼前需用氩弧焊焊接接长,为保证焊接接头具有足够熔深,需要大参数进行焊接。采用直流焊机并联使用解决了焊机电流不足的情况,通过采取垫高镍棒端头,使接缝处于受压状态,以防止裂纹的产生。
Nickel rod needs to be lengthen by argon arc welding before the electroslag refinements, large welding parameters are needed to assure the sufficient penetration. The shortage of current can be resolved by using parallel direct currend arc welding machines, and the cracks can be prevent by raising the end of the Ni rod to make the joints ander compression stress.
