Sumitomo's construction and thermal plant division has been engaged in engineering and construction work for pipelines, in various fields and has developed fully automatic welding for the purpose of increasing of field construction efficiency. For field welding of pipelines, the welding technique used is changed according to the environment. Automatic welding methods for carbon steel are mainly available for gas pipeline field construction. We developed a narrow gap GMAW method (one internal and two external heads) to give greater welding efficiency. In addition, an automatic GMAW method for stainless steel pipe has been developed and will be utilized for LNG terminal piping.
