Title:
WELDING STRUCTURE OF PIPE STOCK AND WELDING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2612427
Kind Code:
B2
Abstract:
PURPOSE: To improve welding strength by forming a through hole with a small diameter part, a large diameter part and a taper face and welding the tip end part of a pipe stock engaged and inserted to the taper face.
CONSTITUTION: The pipe stock 35 is fit and inserted in the through hole 23 from one surface 25 side of a plate 21 and the tip end part 37 of pipe stock 35 is welded from the other surface 29 side of the metal plate 21. The through hole 23 is formed with the small diameter part 27 on the surface 25 side of plate 21, the large diameter part 31 on the surface 29 side of metal plate and the taper face 33 by which the small diameter part 27 and the large diameter part 31 are connected. The tip end part 37 of pipe stock 35 is fit and inserted to the taper face 33 from the surface 25 side of metal plate 21 with the small diameter part 27 of through hole 23. Welding beads are formed from the taper face 33 of through hole 23 including the vicinity of opening end of through hole on the surface 25 side of metal plate 21. The angle of intruding welding beam in the outer circumference of pipe stock 35 is made small, the clearance between the small diameter part 27 and pipe stock 35 is filled with the welding beads and welding strength is improved.
