摘要
从单焊道全位置区段分析、送丝行为分析、焊接弧长 (电压 )、电流行为分析、工艺试验和接头检验等诸方面介绍了管道全位置打底焊焊接工艺特点 。
Backing weld procedure of all -position narrow gap for thick-walled pipe welding was developed by means of analyses and tests, such as all-position single-pass welding section、 wire feeding behavior 、weld arc length 、welding current 、procedure and joint test. The investigative result has general guide significance to producing and testing of all-position equipments。$$$$
