［摘要］焊缝连接是不锈钢结构中主要的连接方式之一。对常用的奥氏体304不锈钢，进行了不锈钢结构对接焊缝连接受力性能试验，共10组120个试件，分别考虑焊条电弧焊（SMAW）、钨极氩弧焊（TIG）和熔化极氩弧焊（MIG）3种焊接工艺和5种板厚。得到了对接焊缝的极限荷载和极限变形，以及焊缝和热影响区强度与母材强度的关系。将试验结果与国外不锈钢结构设计规范以及我国钢结构设计规范进行了对比，提出了适用于我国不锈钢结构对接焊缝连接的设计建议。

Abstract: Weld connection is one of the main connection types for stainless steel structures. One hundred and twenty specimens of butt weld connections made of austenitic stainless steel 304 were tested with different weld procedures such as SMAW, TIG and MIG and five kinds of plate thicknesses. The results obtained the ultimate load and deformation of butt weld connection, and the relationship between the strength of weld metal, metal in heat affected zone and base metal. Comparing the test results, design codes for international stainless steel structures and design code for Chinese steel structures, the weld connection design suggestions of stainless steel structures which apply to China were put forward.
