Abstract

PURPOSE: To make possible the high-performance large-current welding of square pipes by mounting backing strips to the both of web and flange in the corner joint welding of the square steel pipes.
CONSTITUTION: A backing strip 9 supports weld metal and its surfaces to be put in contact with a web 1 and flange 2 are made flat so as to obviate the formation of a clearance. Further the lower side thereof is also made flat to obviate a clearance when put in contact with the flange side strip 8. The one of a rectangle in sectional shape is used. Mounting of the web side backing strip 9 is accomplished by fillet welding 7a or the like to the web 1 prior to assembling of square steel pipes. The top surface and the side face in contact with the flange 2 of the flange side strip 8 are made flat. The flange side strip 8 is mounted by fillet welding 7b or the like to the flange 2 and its position is required to be such a position where its top surface contacts the bottom surface of the web side backing strip 9. If there is a large clearance in this portion, it becomes difficult to prevent the effluence of the weld metal.
