  • Patent Literature 5 US. Patent No. 3,617,710, Specification
  • the welding arcs/electrical discharge arcs are concentrated in the center part of the weld flange whereupon, when the member being welded to is a thin panel, that portion being welded becomes thin and the strength thereof deteriorates, and furthermore, in the worst cases, there is a danger of a hole opening in that portion. This is described with reference to Figs. 1(A) and 1(B). In Fig.
  • an aspect of the present invention is to provide a weld stud wherewith proper welding can be done even when a thin panel is the member being welded to.
  • Fig. 1 diagrams how a known weld stud is welded to a member being welded to, with 1 (A) being a section diagramming the condition during welding and 1(B) being a section diagramming the condition after welding.
  • Fig. 2 is a front elevation of a weld stud relating to one embodiment of the present invention.
  • Fig. 3 diagrams how the weld stud diagrammed in Fig. 2 is welded to a member being welded to, with 3(A) being a section diagramming the condition during welding and 3(B) being a section diagramming the condition after welding. Disclosure of the Invention
  • a weld stud having a weld flange to be welded to a member being welded to, and a portion formed integrally with the weld flange wherein, in the weld flange, the outer edge of the surface on the side to be welded is formed flat by a ring-shaped part of a certain width, and a round conical recess is provided, formed in a round conical shape from the ring-shaped part toward the center, whereupon only the ring-shaped part is welded to the above-described member being welded to.
  • the inclination angle in the conical recess should preferably be 12 to 13 degrees. It is further preferable that the weld flange be formed in a round plate shape with an outer diameter of 13 mm and a thickness of 2mm; that the diameter of the portion adjacent to the ring-shaped part of the conical recess be 10 mm; and that the apex of the conical recess be at a height of 1.2 mm from the weld surface of the ring-shaped part.
  • the portion formed integrally with the weld flange can be made a bolt that rises from the center of the weld flange. That bolt can have M6 (6mm) treads, for example.
  • the weld stud 10 has a weld flange 11 that provides a weld surface that is to be welded to a panel or other member being welded to, and a bolt 13 that is to be attached to another attaching member and constituting a portion formed integrally with the weld flange.
  • the bolt 13 may be formed in some other shape.
  • the bolt 13 portion for example, may be formed as an l-shaped stud, shaped as an l-shaped rod-like part comprising a shaft of a certain height and a head at its end.
  • At least the weld flange 11 portion of the weld stud 10 is to be formed of a metallic material wherewith stud welding is possible.
  • the weld flange 11 is formed overall in a round plate shape that is not thick, of a certain thickness T and diameter D1.
  • the outer edge of the surface of the weld flange 11 on the weld side is formed as a ring-shaped part 14 of a certain width, the surface of which ring-shaped part 14 is formed flat so as to be weldable.
  • the portion inside from the ring-shaped part 14 is formed as a conical recess 15 that is conical toward the center. For that reason, of the surface on the weld side of the weld flange 11 , only the ring-shaped part 14 will be welded to the member being welded to.
  • the bolt 13 is formed so as to rise from the center of the weld flange 11 , that is, from the portion where the conical recess 15 is formed.
  • the inclination angle ⁇ of the conical recess 15 is 12 to 13 degrees.
  • the diameter D1 of the weld flange is 13 mm, while the thickness T thereof is 2 mm.
  • the diameter D2 of the portion adjacent the ring-shaped part 14 is 10 mm, while the apex of the conical recess 15, that is the center thereof, is at a height of 1.2 mm from the weld surface of the ring- shaped part 14.
  • the known weld stud 1 diagrammed in Fig. 1 was welded to a member being welded to 5 that is a thin panel.
  • the diameter of the weld surface of the member being welded to 5 became 9 mm from the center, the weld portion became even thinner with members being welded to having a thickness of 0.7 mm or less, and when another member was combined with the bolt, the weld stud 1 pulled away from the member being welded to 5.
  • the bolt 13 that rises from the center of the weld flange 11 can be made one having M6 (6mm) threads, for example.

Abstract

Un goujon de soudure 10 comprend une bride de soudure 11 adaptée pour être soudée à une pièce à usiner et une partie 13 solidairement formée avec la bride de soudure 11. La bride 11 comporte une surface à souder. La surface comprend une partie annulaire aplatie 14 d'une largeur radiale prédéterminée au niveau d'une des ses périphéries externes et un évidement conique 15 formé de manière conique à partir de la partie annulaire 14 vers son centre, de sorte que seule la partie annulaire est soudée à la pièce à usiner.
