纯铝(L3)接头的焊接工艺与应用

Welding technology and application of pure aluminum (L3) joint

纯铝在焊接过程中存在的主要缺陷是气孔、未熔合、夹杂及夹钨等。通过制定合理的焊接工艺 ,并经过焊接工艺评定 ,探索出最佳焊接工艺参数和相适应的焊工操作手法 ,应用于实践 ,成功地焊出了合格产品。

The defects of welding of pure aluminum are air hole, un interfuse, occlude and holding wolframium, etc. By formulating and evaluating reasonable welding technology, the best welding technology parameters and relevant operation methods for welder are explored and applied, so the qualified products are welded successfully. \[
