摘要：钢结构件中的焊接H型钢，其厚板T形熔透焊缝焊接以人工气体保护焊打底、填充为主，效率较低。通过介绍采用窄间隙气电立焊方法进行H型钢厚板T形接头熔透焊缝焊接的工艺试验，为H型钢厚板T形熔透焊接提供了一种可借鉴的焊接工艺方法。

Abstract： In the welding H-shaped steel of steel structure members， the welding of thick plate T-shape penetration weld is mainly based on artificial gas shielded arc welding， and the efficiency is low. This paper introduces the welding process test of T-shaped joint penetration welding of H-shaped steel thick plate by narrow-gap gas-electric vertical welding method， which provides a useful welding process method for T-shaped penetration welding of H-shaped steel thick plate.

Keywords： steel structure; H-shaped steel; thick plate penetration; narrow-gap gas-electric welding; welding process
