换热器管—板的全位置自动氩弧焊

Full-position Automatic Argon Arc Welding for Heat Exchanger Tube-sheet

报道引进的法国普利苏迪公司全位置管—板焊接设备的成功应用。在管—板自动焊尚无成熟工艺可借鉴的情况下 ,通过焊接工艺试验确定了合理的焊接工艺参数 ,采用该工艺成功地进行了七台列管式固定管板换热器的管—板焊接 ,合格率达到 1 0 0 %。

The paper reported the application of full-position automatic argon arc welding for heat exchanger tube-sheet.The welding machine was imported from PRISUDI CO.France.In the absence of wps,the proper welding parameters were determined through welding process test.7 sets fixed tube sheet heat exchanger's tube-sheets were welded.All the welding quality is up to standard.
