近年来,随着我国铁路运输装备生产要求不断提高,国内专业化货车生产厂家都引进很多自动化焊接生产线,由于新技术和新工艺的引入,自动生产线使用初期经常出现问题。2004年上半年,太原轨道交通装备有限责任公司购置了“货车侧墙自动焊接生产线”设备。侧柱的自动焊接跟踪采用机械式跟踪系统,使用中发现侧柱焊缝基本处于不稳定状态,主要问题有:(1)焊缝不合格,表现为焊缝不匀、焊瘤、偏焊;(2)跟踪不可靠,跟踪失效常常使焊嘴偏离焊道,只能停机处理,自动焊接失败。为此,对跟踪系统关
In recent years, with the continuous improvement of the production requirements of railway transportation equipment in our country, many domestic specialized truck manufacturers have introduced a lot of automated welding production lines. Due to the introduction of new technologies and new processes, problems often arise in the initial use of automatic production lines. In the first half of 2004, Taiyuan Rail Transportation Equipment Co., Ltd. purchased the “automatic welding line of truck sidewall” equipment. Side column automatic welding tracking using mechanical tracking system, the use of the side column weld was found in the basic unstable state, the main problems are: (1) Weld failure, manifested as uneven weld, welding tumor, partial welding; (2) tracking is not reliable, tracking failure often make welding nozzle deviation from the weld, can only stop processing, automatic welding failure. To this end, the tracking system off
