Rail pipe assembling and welding device

The utility model relates to a rail pipe installing and welding device which comprises a fixing base and a pressing plate, the fixing base comprises a bottom plate, a plurality of fixing components are evenly arranged on the bottom plate at intervals, a fixing plate is arranged at one end of the bottom plate, a positioning plate is arranged at the end, close to the fixing components, of the fixing plate, and the positioning plate is vertically arranged. The welding deformation of the rail pipe is greatly reduced through water-cooling welding, the requirement can be met only through simple straightening after welding, the welding quality and the welding efficiency are improved, the rejection rate is reduced, and the production cost is reduced. 本实用新型涉及一种轨管组焊装置，包括固定座和压板，固定座包括底板，底板上均匀间隔设有若干固定构件，底板的一端设有固定板，固定板的靠近固定构件的一端设有定位板，定位板垂直设置，本实用新型通过固定座和压板固定，通过水冷焊接使得轨管焊接变形量大大降低，焊后只需简单校直即可达到要求，提高了焊接质量和焊接效率，降低废品率，降低了生产成本。
