仰平脸单面焊双面成形背面成形的施焊技巧

Welding Technique of Back-shaping of Overhead Weld

文章主要介绍了将电焊机极向改为直流正接,通过改变手法,由“正抬弧”改成“反抬弧”,使背面凸出板面2 mm以上。此手法填补了焊接书籍里所没有介绍的直流J506[E5016]焊条焊接仰平脸的焊接手法,为以后建筑行业提供一条可行范例。

This paper mainly introduces a new welding method.it makes an arc welding machine change to straight polarity direct current and has the are change to are - back and to let the back swell outwards more than 2mm. It is an steady - current overhead single - welding method of J506[ E5016] rod welding that the new method isn＇ t introduced in the reference book for welding. It provides a new workable example for building trades.
