不锈钢薄板的电弧焊,在航空、仪器仪表以及电工制造等方面,这种焊接工艺过程日益重要,甚至是必不可少的生产手段。不锈钢薄板(一般指0.1～0.5毫米厚的带、材)应用于具体结构时,因受原材料尺寸、工件形状的限制,需要拼合,采用脉冲氩弧焊接,可能获得良好气密性和高温强度的高质量平整焊缝接头。焊机对工件施焊的能源采用脉动功率,比单纯直流施焊改善了热循环,对于减少热影响区的尺寸变形、避免熔穿等方面
Arc welding of stainless steel sheet, in the aviation, instrumentation and electrical manufacturing, etc., this welding process is increasingly important, and even essential means of production. Stainless steel sheet (generally 0.1 ~ 0.5mm thick tape, material) applied to the specific structure, due to the size of the raw materials, the shape of the workpiece, the need for flattening, the use of pulsed argon arc welding, may obtain good air tightness and high temperature strength High-quality flat weld joints. Welder on the workpiece welding energy use pulsating power, compared with pure DC welding to improve the thermal cycle, for reducing the size of the heat-affected zone deformation, to avoid melting penetration and so on
