我厂焊工100多名,CO_2弧焊机40多台,逐步代替了手工电弧焊。近几年来生产的长途客车,10吨、12吨、16吨、20吨吊车专用车架全部采用了CO_2气体保护焊。以前清理导电嘴和喷嘴粘上的CO_2飞溅物的办法是涂硅油,成本高、较麻烦。我厂尝试用石灰水代替硅油。通过实验试用一段时间之后,认为这一方法是可行的。制作方法:将纯石灰用水调或水溶液稀糊状,将导电嘴和喷嘴醮上一层薄薄的稀糊状石灰约0.1毫米,就制作完成。 (1)稀糊状石灰含水,对焊接不利。解决
I plant more than 100 welders, CO_2 arc welder more than 40 units, and gradually replace the manual arc welding. In recent years the production of long-distance buses, 10 tons, 12 tons, 16 tons, 20 tons of cranes dedicated frame all the CO 2 gas shielded welding. The previous method of cleaning CO 2 spatters on the conductive nozzle and the nozzle is to coat the silicone oil, which is expensive and troublesome. I try to use lime water plant instead of silicone oil. After experimenting for some time, this method is considered feasible. Production Methods: The pure lime water or water solution paste paste, the nozzle and nozzle 醮 on a thin layer of thin paste of lime about 0.1 mm, on the production is completed. (1) thin paste of lime water, adverse to welding. solve
