1, traditional electroless copper production process need to be used the industrial chemicals such as a large amount of sulfuric acid, copper sulphate and NaOH, produces simultaneously a large amount of waste gas, waste water, to environment, to the Manufacturing Worker is healthy larger infringement is arranged.
2, energy consumption is high, and water, power consumption are large.To produce ￠ 1.0mm solid core welding wire as example, the direct operating costs such as required water per ton, electricity, labor wage and industrial chemicals are more than 1400 yuan.
3, complex manufacturing, poor stability, the finished product rate is low, and waste of raw materials is large.Traditional electroless copper production technology is among the dynamic process all the time, require extremely strict to each process quality, any one link occurs unusually in the production procedure, will produce a large amount of waste silks or pending product, and each link be not easy unusually again timely discovery.
4, product rust-proof life time of guaranteeing the quality is short.Traditional electroless copper production technology, copper ion and iron ion junction surface acid large, moisture is high, that the copper layer adheres to is not firm, uneven, easily come off and get rusty, and often occurs the copper layer in the welding process and peels off the obstruction wire feeding mouth, the defectives such as wire feed rate is unstable, and it is large to splash.
5, traditional handicraft is produced CO
2The gas shield solid core welding wire; specific area is descending along with the increase molten drop diameter increase of gage of wire; can not form and reduce the capillary enough diaphragms of molten drop, under the effect of various arc forces, produce and splash more greatly, therefore can only be limited to the following welding wire production of ￠ 1.6mm.
Summary of the invention
Technical problem to be solved by this invention provides a kind of with physics oxidizing process production CO
2The method of gas shield solid core welding wire; the welding wire surface of required diameter generates oxide-film after utilizing oxide-film generation equipment to finish draw; replace existing electroless copper method with the physics oxidizing process; the oxide-film that generates is evenly fine and closely woven ultra-thin; it is antirust that rust-proof effect is better than copper facing; electric conductivity is stable simultaneously, and Wire Performance is good.

4The phase oxidation film has good antirust electric conductivity and feeding stability, has solved the easy moisture absorption of copper plating soldering wire and has adhered to not firmly, roughly falls copper and easily becomes rusty, and the copper layer peels off defectives such as stopping up wire feeding mouth.
3, generate oxide-film under the hot environment, reduced the water content of welding wire, oxide-film is coated on the molten drop surface energy and makes the molten drop smooth transition during welding, and the bulky grain generation of splashing greatly improves welding technological properties when having reduced welding.
4, the CO of this method production
2The gas shield solid core welding wire is keeping characteristic and the chemical analysis of welding stick original material material, has stopped the scaling loss of copper plating soldering wire acidity to manganese silicon, has guaranteed physical property and the chemical analysis of deposited metal.
5, reduce cost, increase the benefit: whole oxidizing process mainly is exactly electricity consumption and controllability supplemental oxygen, has abandoned change plating the production technology entire cost that produces and the input of changing the plating production equipment of former copper plating solid core welding wire, and production cost will descend more than 50%.
6, cleaning ambient green non-pollution: because discarded traditional copper-plating technique, just cut in the production process of welding wire sulfuric acid vapor to the infringement of health, this product also just can not produce copper particulate flue dust in the welding use procedure, can not produce pollution to environment, be the environmental protection new process for producing that the sector is worth promoting.
