淮北华星矿筛厂在设备更新过程中,专门订购了一台新型电脑控制龙门式氩弧焊专业焊机。在使用过程中,因筛网的规格不同,各种参数难以设定,因此,在焊接过程中经常出现过焊和漏焊现象。通过实验,对各因素进行分析对比,找到了使焊接效果处于最佳状态时各参数值。 1 焊接原理及过程 新型自动氩弧焊机在工作时:将筛条穿入梳子内,压紧于工作台上,工作台连接电焊机的负极,调整好铈钨电极与筛 Huaibei Huaxing mine sieve plant in the process of equipment updates, specifically ordered a new computer-controlled gantry welding professional welding machine. In use process, due to the different specifications of the screen, a variety of parameters is difficult to set, therefore, in the welding process often appear welding and missed welding phenomenon. Through experiments, analysis and comparison of various factors to find the welding results in the best state of each parameter value. 1 welding principle and process of new automatic welding machine at work: the screen into the comb, pressed on the table, the table connected to the negative electrode welding machine, adjust the cerium tungsten electrode and the screen
