摘要
介绍耐候富氩混合气体保护焊丝的冶炼、轧制、拉拔及检测的过程。所试制的焊丝与母材匹配良好 ,其焊接性能试验表明 :σb≥ 44 0MPa ,AKv(- 40℃ )≥ 47J,AKv(常温 )≥ 80J,兼具其他优良性能 。
To introduce the smelting,milling,drawing and testing process of atmospheric corrosion resisting welding wire for Ar rich mixed gas shielded welding The welding wire developed is fit for master material Welding behaviour test indicates that σ b≥440?MPa, AK v(-40?℃)≥47?J, AK v(room temperature)≥80?J The welding wire also has other excellent behaviours,it is applied to weld the steel which is atmospheric corrosion resisting such as rolling stock
