Inner welding process for inlaying section of U-shaped rib

The invention relates to an internal welding process for a U-rib inlaying section, which is characterized in that the specific welding process is as follows: an endoscope camera is mounted on a gun head of a welding gun, and the state of an inner cavity of the U-rib inlaying section is observed through an electronic display screen, so that the problem that a worker cannot observe the inlaying section in a welding cavity through a hand hole by holding the welding gun by hand during welding operation is solved; the visual welding operation is realized; the protective goggles are used as protective covers, damage to the lens of the endoscope caused by high temperature and splashing during welding operation is avoided, meanwhile, the protective goggles are low in cost, durable and convenient to replace, and the operation cost is effectively reduced. 本发明涉及一种U肋嵌补段内焊工艺，其特征在于：具体焊接工艺如下：在焊枪枪头安装内窥镜摄像头，通过电子显示屏观察U肋嵌补段内腔状态，解决了焊接作业时，工人手持焊枪通过手孔焊接腔内嵌补段无法观察的问题，实现了可视化焊接作业；以护目镜作为保护罩，避免了焊接作业时的高温、飞溅对内窥镜镜头的损伤，同时，护目镜低廉耐用，更换方便，有效降低了作
