对大中型电机用扁铜带的焊接,原采用 LP—75型对焊机焊接,功率小焊不透,功率大易击穿。由于焊接工艺不过关,一直不能承担上级下达的生产任务。经分析,认为在焊接功率(电压、电流)、压缩行程、自动加压弹簧的距离、通电时间四个因素中,焊接电流是主要矛盾。优选过程:改用 LP—25型焊机,先用“瞎子爬山法”对焊接功率进行优选。 Large and medium-sized motor with flat copper ribbon welding, the original LP-75-type welding on the welder, welding power through the small, power easy to wear. Due to the welding process, however, it has not been able to undertake the tasks assigned by superiors. After analysis, it is considered that the welding current is the main contradiction among the four factors of welding power (voltage and current), compression stroke, distance of self-pressurizing spring and energizing time. The preferred process: switch to LP-25 type welder, first with “blind hill climbing method” on the welding power optimization.
