摘要:
分析了埋弧焊焊缝中产生的气孔、夹渣的主要化学成分。从焊剂碱度,机械夹杂物,H20、S、P含量等方面,阐述了焊剂成分对焊缝中气孔、夹渣的影响。结果表明,在焊管生产时,应尽量采用中性、酸性焊剂,并尽量减少焊剂中的铁屑、油污、锈等机械夹杂物含量,同时应防止焊剂中的S、P偏析物的产生。
Abstract:
This article analyzed main chemical composition of gas pocket and slag inclusion generated in SAW weld,and expatiated effect of welding flux composition on gas pocket and slag inclusion in weld from several aspects,such as welding flux alkalinity,mechanical inclusions,moisture,S and P content.The result showed during welded pipe production,it should,as far as possible,adopt neutral and acidic welding flux,decrease content of mechanical inclusions in welding flux,such as scrap iron,oil contamination and rust,meanwhile,avoid S and P segregation generating in flux.
