Product description

The transverse seam automatic welding machine is a new generation of high-efficiency vertical cylinder transverse seam single-sided submerged arc welding machine independently developed and produced by Nanjing NAEC Electric Co., Ltd. with new welding technology and process. It has the advantages of high efficiency, stable performance, good welding quality and good working conditions. The whole set of equipment is mainly composed of welding walking frame, automatic submerged arc welding system, power distribution cabinet, flux holding mechanism and flux recycling system. The machine relies on hanging the frame on the wall panel (normal installation construction) or ring track (inverted installation construction) to complete the girth welding. According to the needs of the project, the maximum plate width of the frame can reach 4.8m (customized).
