水电站深孔弧形闸门不锈钢面板塞焊技术

Plug weld technology on stainless steel plate of bottom radial gate of hydraulic power station

某水电站设计深孔弧形闸门塞焊奥氏体不锈钢面板,对塞焊技术要求高,文章通过研究奥氏体不锈钢面板塞焊异种钢焊接技术,介绍了该焊接技术的工艺评定、焊接变形控制和焊接方案实施要点。

Austenitic stainless steel plates were welded to low alloy steel of bottom radial gate of a hydraulic power station by plug weld, and it＇s high requirement for the plug weld. According to the research about plug welding technology between low alloy steel and austenitic stainless steel, the welding procedure qualification, welding deformation control characteristic and the welding program im- plementation key points are introduced in this paper.
