gas welding

Aimed at the difficulty in thin plate welding,and the status of poor welding quality,and more welding defects traditional welding characteristics was analyzed,and the new technics of the electrode manual weld with wire for low carbon steel thin plate was explored based on the characteristic of gas welding.

针对薄板焊接操作难度大,焊缝质量差,易产生烧穿、焊瘤等缺陷的现状,在对传统焊接工艺特点分析研究的基础上,结合气焊的特点,探索出了低碳钢薄板送丝手工焊条电弧焊新工艺。

To meet the need of production and guarantee the quality of castings and welding-on,the technical system and the testing standard of gas welding and electric act welding have been studied and set up,which can be used to compensate for some defects of nodular iron castings.

针对生产实际的需要 ,为确保铸件焊补的质量 ,研究并制定了球墨铸铁铸件缺陷的气焊与电弧焊工艺及验收规

Two combined welding processes for 65Mn high strength strip steel,including gas welding-forging and pressing-tempering and argon arc welding-heat treatment,are introduced in the paper.

研究气焊—锻压—热处理和氩弧焊—热处理两种复合工艺连接高强度钢带。
