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.

用自制腐蚀磨损验机对耐蚀堆焊层在不同介质中腐蚀磨损性能进验，结果表明：腐蚀介质不同，堆焊层磨损速率也不同。

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方法，研究双层药皮对钛钙型不锈钢焊条影响。

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体保护堆焊角变形动态过程。为反映夹具和焊接件接触状态，将夹具和焊件统一建立有限元模型。
