Document Type and Number:

WIPO Patent Application WO/2018/066136

Kind Code:

A1

Abstract:

This welding device welds together the outer circumferential edges of two overlapping atypically-shaped plates and comprises: a rotating table upon which the two atypically-shaped plates are fixed in an overlapping state; a torch unit having a welding torch arranged at a position facing an outer circumferential edge of the two atypically-shaped plates fixed to the rotating table; a first torch drive unit whereby the welding torch inclination and spacing relative to the outer circumferential edge can be changed; and a first control unit that controls the first torch drive unit such that the inclination of the torch and the spacing between the outer circumferential edge and the welding torch are constant along the circumferential direction of the atypically-shaped plates, said welding torch inclination being relative to the tangent of the outer circumferential edge of the two rotating atypically-shaped plates.
