［摘要］焊縫連接是不銹鋼結(jié)構(gòu)中主要的連接方式之一。對(duì)常用的奧氏體304不銹鋼，進(jìn)行了不銹鋼結(jié)構(gòu)對(duì)接焊縫連接受力性能試驗(yàn)，共10組120個(gè)試件，分別考慮焊條電弧焊（SMAW）、鎢極氬弧焊（TIG）和熔化極氬弧焊（MIG）3種焊接工藝和5種板厚。得到了對(duì)接焊縫的極限荷載和極限變形，以及焊縫和熱影響區(qū)強(qiáng)度與母材強(qiáng)度的關(guān)系。將試驗(yàn)結(jié)果與國(guó)外不銹鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范以及我國(guó)鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范進(jìn)行了對(duì)比，提出了適用于我國(guó)不銹鋼結(jié)構(gòu)對(duì)接焊縫連接的設(shè)計(jì)建議。

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.

Keywords: stainless steel; butt weld; experimental investigation; design suggestion
