使用洁净的焊材进行填丝钨极氩弧焊

以获取优质的镍基合金堆焊层。为保证焊接质量

同时对合金堆焊的焊接过程控制提出了明确要求。通过试验确定了这种镍基合金堆焊的可靠工艺

指导现场进行生产。

Abstract

In this paper

a overlaying procedure of nickel base alloy Inconel 625 on the surface of marine high strength steel E36 is analyzed. Manual GTAW is used

and the welding current

arc voltage and welding speed are strictly controlled to ensure low heat input in overlaying process. Meanwhile

the low interpass temperature is maintained in welding process. The GTAW with clean welding materials in a clean welding environment is required to obtain high quality nickel base alloy layer. In order to ensure the welding quality

the welding process control of alloy overlaying is clearly required. According to the test

this reliable overlaying procedure of nickel base alloy is confirmed

and is provided as a guideline for the production.
