Claims

[Claims for Utility Model Registration] 1. In an apparatus for automatically manufacturing a beam with a welded structure: A pair of workpiece holders arranged symmetrically along the center line in the movement direction of the workpiece at the inner lower part of the main body frame. Torch holder support arms are provided on the guide roller supports, each of which is pivoted at its rear position along the movement direction of the workpiece so that its base end can be rotated in the vertical direction. teeth,
A pair of plate cams detect the starting ends of the flange material to be processed and the web material and set the welding torch in a standby position, and a copying roller is installed on the surface of both workpieces with their axes aligned on the same vertical plane. and a welding torch holder is attached so as to be movable relative to the welding position so that the tip of the welding torch faces the intersection of the extension lines passing through the contact points of both release rollers with each workpiece. A welding position setting guide device for a welding torch in an automatic welded structure beam manufacturing device, characterized in that the device has a certain configuration. 2. The plate cam and release roller for detecting the welding start position attached to the tip of the welding torch holder support arm, and the position of the welding torch operated by these, are aligned with the web material and flange material of the workpiece. A claim in which the web material is welded to the flange material is not simultaneously welded on both sides, but is welded at shifted positions on both sides with respect to the welding location. 1. A welding position setting guide device for a welding torch in the automatic welded structure beam manufacturing device according to item 1. 3 The plate cam is boat-shaped, and the distance between the lower end of its slanted side and the contact point of the copying roller against the workpiece is
3. The welding position setting guide device for a welding torch in an automatic welding structure beam manufacturing apparatus according to claim 1 or 2, wherein the length required for the welding torch to be in a welding starting position is at least 20 mm.
