利用氩气保护罩提高镍管的焊接质量

Improving Weld Quality of Nickel Pipe Using Argon Gas Shielded Cover

分析了纯镍的焊接性能及其影响因素。结合实际工作中的应用,针对工业纯镍的管材焊接工艺进行探讨。在钨极氩弧焊(TIG焊)的基础上用自制氩气保护罩来避免镍在焊接过程中高温区域氧化严重的问题,同时结合其它保护措施及合理的焊接规范,明显地提高了镍管的焊接质量。

The welding properties and its impact factors of pure nickel is analyzed.Combined the application of actual work,the welding procedure of industrial pure nickel pipe is discussed.To avoid high temperature area serous problem of nickel oxygenized during welding using self-command argon gas shielded cover on the basis of TIG,meanwhile combine other protective measures and reasonable welding specification to improve the welding quality of nickel pipe distinctly.
