酸洗-轧机联合机组生产线上的闪光对接焊机,由于原料板型的影响及操作经验不足,使焊缝难以保证,过轧机时焊缝断带率较高,影响冷轧产品的质量。通过对焊接过程中初始闪光、过梁爆破以及顶锻各阶段的监控,对移动夹具的给进速度的积分值、材料的可焊接性以及闪光行程、顶锻行程等焊接参数进行调整,对影响焊缝质量的各种因素进行分析,对焊接参数进行了修正,如板厚为2.0mm的板材焊接电流调节器积分增益由原来的0.000 02调整为0.000 03,基本解决了焊缝质量问题。
Because of the influence of raw material plate type and lack of operation experience, it is difficult to guarantee the welding seam. The breakage rate of the weld in the rolling mill is high, which affects the quality of cold rolled products. Through the monitoring of the initial flashing, the superstructure blasting and the upsetting stages in the welding process, the integral values of the feeding speed of the moving fixture, the weldability of materials and the welding parameters such as the flash stroke and the forging stroke are adjusted, Weld quality analysis of various factors, the welding parameters were amended, such as the thickness of 2.0mm plate welding current regulator integral gain from 0.000 02 to 0.000 03, basically solved the problem of weld quality.
