This paper studied the blending of chemical copper-plated solution and its productive procedure for solving quality problem present in the copper-plated welded wire protected by carbon dioxide gas, that is easy corrosion, stripping off and short pieserving time. Two blendings were suggested such as alkaline and acid copper-plated solutions which raw material were easily found, widely applicated and easily operated. The new technique is dragging and pulling twice, the procedure is simple and the copper-plated...

This paper studied the blending of chemical copper-plated solution and its productive procedure for solving quality problem present in the copper-plated welded wire protected by carbon dioxide gas, that is easy corrosion, stripping off and short pieserving time. Two blendings were suggested such as alkaline and acid copper-plated solutions which raw material were easily found, widely applicated and easily operated. The new technique is dragging and pulling twice, the procedure is simple and the copper-plated layer is uniform, strong bond force and good corrosion proof. Therefore, it has signifance for guiding chemical copper-plated welded wire protected by carbon dioxide gas.

本研究立足于解决国内各厂家HO8Mn2Si二氧化碳气体保护镀铜焊丝产品中出现的质量问题,如镀铜层易锈蚀、脱落、保存期短等缺陷,着重研究了化学镀铜液的配方及生产工艺流程和条件。采取两次镀、两次拉拔抛光新工艺,工艺简单,镀层均匀,结合力强,抗蚀性能好。文中提供了碱性镀铜液配方和酸性镀铜液配方,原料易得,适应范围广,容易操作。所得的结果对二氧化碳气保护焊丝化学镀铜生产具有指导意义。

Through corrosion experiment of neutral salt spray(NSS),the new technology of adding a kind of passive accelerator to the passive system of ethyl alcohol-benzotrial-chloride-zole has been studied.A new WP-1 type passivation-promotor was selected.After passive treatment,the rustproof ability of kinds of coppered welding wires has been improved obviously.

采用中性盐雾腐蚀试验,对乙醇—苯骈三氮唑钝化工艺进行了改进,研制出WP─1型镀铜焊丝钝化剂。电镀和化学镀铜焊丝经钝化后抗蚀性能均有明显提高。

In this paper, the inhibition treatment of the copper plating wire used in CO 2 gas shielded arc welding is dealed with.The factors affecting the quality of the copper plating wires such as the density of BTA,the lasting time of the inhibition treatment and the preparation of the composite corrosion inhibitor are studied.The best process is proposed too.

对二氧化碳气体保护焊镀铜焊丝进行了缓蚀处理试验。试验研究了BTA浓度 ,缓蚀处理时间及复合缓蚀剂对镀铜焊丝质量的影响 ,并推荐了最佳工艺条件
