用背面焊道焊接设备焊接圆筒容器简体纵缝,是压力容器制造过程中的重要工序,因此要求有很高的焊接质量。改进前的焊接设备是在框架上装有能调整衬垫装置的支柱和固定简体的压板。在上面还有埋弧焊机和可调的行走滚轮。焊接时、先用起重机吊钩把筒体吊到支
Welded cylindrical containers with a back-side bead welding device Simplified longitudinal slits are important processes in the manufacture of pressure vessels and require a high degree of weld quality. Before the improvement of the welding equipment is installed in the frame can be adjusted to the pillars of the device and a fixed pressure plate. In the above there are submerged arc welding machine and adjustable walking wheel. Welding, the first crane hook to the cylinder hanging branch
