Description

Welding structure of rail components

The present invention relates to a welded construction of a rail component, and more particularly to a method of joining a rail component using spot welding technology, and the welding structure is more stable and convenient to construct.

The "Embosses and method of using same for attachment of members" of the U.S. Patent No. 6,244,679, the disclosure of which is incorporated herein by reference. An attachment surface for attaching the member to another member such that each attachment surface of the attached member is substantially adjacent; and an embossment from the plurality One of the members of the member is attached to a surface protrusion for attaching the member to another of the plurality of members, the embossing contacting the attachment surface of the other member and providing a gap therebetween And a plurality of members, wherein the plurality of members comprise a first member and a second member attached to each other, and the first member has at least one embossment protruding from the attachment surface thereof, the embossing being adjacent to the first An attachment surface of the two members, the embossment being adjacent to the attachment surface of the second member and providing a gap between the first and second members; and wherein the second member has at least one attached thereto Elevation of the surface protrusion . The technique disclosed in the prior art patent is mainly a spot welding welding method, which is suitable for welding joints between the same similar plate shapes, for the combination of different shapes, such as the combination of round bars and flat plates. , there is no disclosure.

In general, this type of spot welding mainly uses a large enough current to generate resistive heat at the contact of the metal material to heat the contact center to a molten state to form a molten pool. Solder joints are formed after cooling. When a non-planar small metal member such as a round rod is welded directly to a planar metal member such as a sheet by spot welding, the non-planar small metal member and the planar metal member are The surface contact is only in tangential contact, resulting in a very small pool of molten pools and solder joints at the center of the soldering, and the robustness after soldering is not excellent.

Therefore, it is necessary to provide a welded construction of the rail member to improve the aforementioned drawbacks.
