筒式加压溶液过滤器在气保焊丝生产中的应用

Application of cartridge pressure filter for solution to gas shield welding wire production

介绍简式加压溶液过滤器在气保焊丝生产中选型、安装、使用和维护过程中应注意的问题。气保焊丝生产的镀铜工序使用筒式加压溶液过滤器，可有效延长硫酸铜镀液的使用寿命，成品焊丝表面光泽度好，缠绕后在50倍显微镜下观察，铜层结合力良好，无起鳞、麻点等表面质量问题，铜镀层均匀，厚度稳定在0．2～0．25μm，防锈性能良好，焊接效果好，焊接时送丝均匀、稳定。

To introduce matters need in attention of cartridge pressure filter for solution＇ s type selection, application, usage and maintenance in gas shield welding wire production. Cu-plating procedure of gas shield welding wire production uses cartridge filter for solution, which can effectively extend copper sulfate solution＇ s usage life, the finished product has good gloss, to inspect the twisted wire under 50 times microscope, the copper layer has good bond, no delamination and pock surface quality problems. Copper plating layer is even, and thickness is 0.2 - 0.25μm, good rust-proof performance and welding result, and wire feed is even and steady.
