堆焊

A test of arrosion performance of anticorrocive built-up weld layer in different meeiums was con-ducted by using a self-made arrosion testing machine.

用自制的腐蚀磨损试验机对耐蚀堆焊层在不同介质中的腐蚀磨损性能进行了试验，结果表明：腐蚀介质不同，堆焊层的磨损速率也不同。

The effects of double coating on the pores of lime titania type stainless steel electrode are studied with high speed cinecamera, oscillograph, optical microscope, SEM with EDS, etc.

采用平板堆焊、高速摄影、波形析、光学金相、扫描电镜能谱析等测试方法，研究了双层药皮对钛钙型不锈钢焊条气孔的影响。

The contact between welding plate and fixture is treated as constraint in the finite element model of dynamic welding angular distortion simulation for overlayer in CO2 gas arc welding.

摘要采用有限元数值模拟方法研究了CO2气体保护堆焊的角变形动态过程。为了反映焊接件的接触状态，将焊件统一建立有限元模型。
