JPS57193282A - Portable welding device for belt-like metallic plate - Google Patents

Abstract

PURPOSE:To weld belt-like metallic plates safely and accurately with simple installations in a welding machine for said plates by separating a shearing device and a welding device for the metallic plates. CONSTITUTION:A welding device for belt-like metallic plates is constituted of an end part shearing device 2 and a welding device 3 for metallic plates. The trailing end part of the preceding metallic plate to be welded and the leading end part of the succeeding metallic plate are inserted respecrively into the clearances of the clamping devices 8, 8 of the device 2, and after a suitable projection size is provided, handles 12, 12 are turned to clamp these with clamping plates 11, 11. The end parts of both metallic plates are cut straightforward by moving a cutting blade 4 downward by the rotation of a handle 5. Both metallic plates are removed from the devices 8, 8, and are transferred to the welding device 3 of next stage. Here, too, the end parts of both metallic plates are inserted into the clearances of clamping devices 9, 9 to fix these with clamping plates 11, 11. While a welding torch 17 is moved on the weld line of both metallic plates, these plates are welded by the arc.
