今年我厂采用了脉冲等离子全位置小口径对接焊新工艺。并在制造400吨/时锅炉和1000吨/时锅炉中应用,共焊2300个接头,焊接情况良好。脉冲等离子弧焊应用于小口径全位置焊接是最近发展起来的一种熔焊工艺。等离子弧焊具有能量密度大,穿透能力强,对装配要求低,适于焊接可焊性差的材料等优点。脉冲等离子弧焊就是在等离子弧焊的基础上把焊接电流变为周期性的脉冲电流而发展起来的。脉冲等离子弧焊具有以下优点:
This year I plant a pulse plasma full position small caliber butt welding new technology. And in the manufacture of 400 tons / hour boiler and 1000 tons / hour boiler application, a total of 2300 joints welded, welding in good condition. Pulsed plasma arc welding used in small diameter full position welding is a newly developed fusion welding process. Plasma arc welding with energy density, penetrating ability, low assembly requirements, suitable for welding solderable materials such as poor. Pulse plasma arc welding is the plasma arc welding based on the welding current into a periodic pulse current and developed. Pulsed plasma arc welding has the following advantages:
