Large Rotary Capacity Automatic Rotator For Silo Tank Welding Production

.Large Rotary Capacity Automatic Rotator For Silo Tank Welding Production

Heavy pressure vessel procuction automation requires rigid welding rotator and large size welding Column and Booms or welding platforms, which carries several welding heads.The narrow gap SAW technique is used on workpieces for which the plate wall is exceptionally thick, typically 50-350 mm. Workpieces such as this are usually needed, for example, in large pressure vessels and other components used in the energy, offshore and chemicals industries.A deep yet narrow gap provides outstanding strength, thanks to the low heat input. A narrow, preformed welding gap also reduces the gap volume and decreases the amount of fillet material needed.Welding process productivity can be significantly improved by using a tandem narrow gap process, in which two wires are used simultaneously.
