摘　　要：CO2气体保护实心焊丝化学镀铜由于废水、废气较少,工艺操作简便,成本低廉,已被广泛采用.电解清洗通常采取“阳-阴-阳-阴-阳”极区布置,经高浓度、加热、大电流密度的电解碱洗,配合常温、较低电流密度的电解酸洗除去钢丝表面油脂后,在35 ～ 65℃,硫酸铜质量浓度为30 ～ 80 g/L,硫酸质量浓度为50～120 g/L,外加添加剂的酸性溶液中施镀2～5s,同时做好清洗液及镀液的清洁维护,即可得到较好质量的CO2气保焊丝.CO2 gas shield solid welding wire chemical copper plating has been widely used because of less waste water, waste gas, easy process operation and low cost. Electrolytic cleaning usually adopt ＂cathode - anode - cathode - anode - cathode＂ region arrangement, after removing the grease of wire surface through high concentration, heating and high current density electrolytic caustic washing, and cooperate with normal temperature, low current density electrolytic acid, at 35 ~ 65 22 ,the copper sulfate concentration is 30 ~ 80 g/L, sulfuric acid mass concentration is 50 ~ 120 g/L, plating 2 ~ 5 s in the additional additive acid solution, keep the washing and plating liquid cleaning and maintenance, and then achieve good C02 gas shield welding wire
