英译汉,不要机翻!
Resistance welding is a group of welding processes in which coalescence is produced by the heat obtained from resistance of the work piece to electric current in a circuit of which the work piece is a part and by the application of pressure.There are at least seven important resistance-welding processes.These are flash welding,high-frequency resistance welding,percussion welding,projection welding,resistance seam welding,resistance spot welding,and upset welding.They are alike in many respects but are sufficiently different.

答案

电阻焊接是一组焊接工序,它是通过工件电阻和电路电流得到的热量结合在一起的.其中,工件也是电路的一部分,并应用了电压.至少有七个重要的电阻焊接工序,分别是,闪光焊,高频电阻焊,冲击焊,凸焊,电阻缝焊,电阻点焊,电阻对接焊.它们有很多相似之处,但也有显著区别.
