摘要

层流等离子作为一种新型热源

在焊接领域的应用尚未见报道。对层流等离子在焊接领域的应用展开研究

进行了层流等离子焊接和层流等离子-MIG复合焊焊接试验。结果表明

层流等离子熔入型焊接具有形成焊缝的能力。通过采用层流等离子熔壁型焊接

可以在不开坡口、保留2 mm间隙的情况下完成12 mm厚Q235A钢板的焊接

且形成的焊缝中熔宽上下几乎一致。

Abstract

As a new heat source

laminar plasmahas rarely been reported to be used in welding field. In this paper

laminar plasma welding and laminar plasma-MIG welding have been simultaneously implemented. The results show that fusion-type laminar plasma welding has a capability of forming weld. Fusion wall-type laminar plasma welding

in case of canceling the groove and retaining a2 mm gap

is qualified for the welding of Q235 A steel plate with a thick of 12 mm. The upper and lower pool widths in the as-formed weld are almost the same.
