1·The procedure using anneal instead of normalizing will improve the productive efficiency of electroslag welding joint.
用退火代替正火后的电渣焊工艺可大大提高生产效率。
2·The re-bar end used for electroslag welding should be straight, flat and clean free of U-shaped, bruising, concave and convex, bending or distorted deformations.
电渣压力焊焊接使用的钢筋端头应平直、干净，不得有马蹄形、压扁、凸凹不平、弯曲扭曲等严重变形。
3·Within 200mm area of re-bar end surface, it should be free of rust, oil dirt, concrete slurry etc. The contaminated re-bar should be cleaned for electroslag welding.
钢筋端部200 mm范围不应有锈蚀、油污、混凝土浆等污染，受污染的钢筋应清理干净后才能进行电渣压力焊焊接。
4·According to the specification of equipment, the hardware and PLC application software have been designed. This control system has been used in double wires electroslag welding.
根据设备的技术要求设计了系统硬件和PLC应用软件，该系统已用于自制双丝电渣焊设备。
5·Nickel rod needs to be lengthen by argon arc welding before the electroslag refinements, large welding parameters are needed to assure the sufficient penetration.
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。
