PURPOSE:To enable the welding of thin plate member each other so as to show an excellent external appearance simply and in short time by forming with projection the welding part to cope with the deformation due to welding heat with subjecting the welding part of a work to pressing in advance and by subjecting to some finishing grinding after welding. CONSTITUTION:The projection parts 30b, 32d of the prescribed shape to project paward are formed by subjecting to pressing the end part of two sheets of thin plate member 20, 22 respectively. A brazing filler metal 36 is arranged on those projection parts 30b, 32d of the respective member 20, 22 after their overlapping with abutting and the members 20, 22 are subjected to brazing by heating this brazing filler metal 36. The smooth external surface is obtd. by removing the brazing filler metal projecting to the outer part by a grinder, etc. after cooling this members 20, 22 for the prescribed time further. The welded zone 34 of the thin plate member which can hold the strength sufficiently besides having said feature is thus obtainable.
