Zusammenfassung:PROBLEM TO BE SOLVED: To facilitate continuous welding with high quality and reduce a processing cost of a joint portion and facilitate tack welding works and make a groove butt welding method using an insert member spread out to a wide range of industrial fields. SOLUTION: The groove butt welding method using an insert member comprises a thickness A of a contact surface 6 keeping in contact with a V-shaped groove joint 2 of a base metal (metallic pipe material 1), an insert material forming step for forming the insert member 3 in which the relation with a thickness B to a space direction of the groove joint is A
