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.

用自制的腐磨损试验机对耐在不同介质中的腐磨损性能进行试验，结果表明：腐介质不同，的磨损速也不同。

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、高速摄影、波形分析、光学金相、扫描电镜能谱分析等测试方法，研究药皮对钛钙型不锈钢条气孔的影响。

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CO2气体保护的角变形动态过程。为反映夹具和接件的接触状态，将夹具和件统一建立有限元模型。
