CRRC Yongji Electric Co.,Ltd. 基于电弧钎焊的原理和特点确定了镀铝锌板与不锈钢板电弧钎焊的工艺方案,根据母材选定焊接电源及焊丝,通过工艺试验及金相分析确定了镀铝锌板电弧钎焊的工艺参数。结果表明,电弧钎焊实现了异种金属之间的直接连接,尤其是对于有镀锌、镀锡、镀铝锌等镀层的板材,焊后能确保焊缝的抗腐蚀性能,对于生产设计的推广应用具有积极意义。 By understanding the principle and charac-teristics of arc brazing,we can determine the process plan for arc brazing of aluminized zinc and stainless steel plates. The welding power source and welding wire are selected according to the base material. The welding parameters of the aluminized zinc plate are determined through process tests and metall-ographic analysis. Arc brazing achieves a direct welding con-nection between dissimilar metal,especially for galvanized,tinned,aluminized zinc plates and other coatings. It can ensure the corrosion-resistant capabilities after welding, and would be significant for the popularization and application upon pro-duction design. 镀铝锌板 MIG电弧钎焊 铝青铜焊丝 焊接规范 aluminized zinc plate MIG arc brazing aluminum bronze welding wire welding specification TG454 2022-03-08 1 50
