手工钨极氩弧焊在水套炉内置小盘管焊接中的应用

摘要

目前在采油站油井安装的加热装置——水套炉的修复过程中,经常会遇到一些小管径管道的焊接工作,如果采用手工钨极氩弧焊打底,手工电弧焊填充盖面的工艺方法,可以得到优质的焊接质量,能够提高焊口的合格率.%At present in the repair process of water jacket furnace in the well installation of oil production station, it often encounters some small diameter pipe welding work. If using TIG primer and manual arc welding filler cap surface process, you can get qualified welding weld and improve the pass rate of welded junction.
