Document Type and Number:
WIPO Patent Application WO2004028738
Kind Code:
A3
Abstract:
The invention relates to a burner (10) comprising a non-melting electrode, such as a plasma burner, a TIG burner, or a burner for a laser welding process, said burner comprising a body (27), a handle (28), and an associated set of tubes (23), at least two wire supplying devices (30, 31) respectively supplying one welding wire (13, 32) or an additional material. The invention also relates to a welding method using one such burner (10). In order to provide one such burner (10) with a very simple and compact structure comprising two wire supplying devices (30, 31), said wire supplying devices (30, 31) are laterally fixed in relation to the burner body (27) or the handle (28) or the set of tubes (23), or beneath the same, and one autonomous receiving element (43) for the welding wires (13, 32) or the additional materials is connected to the burner body (27) in such a way that the supply of the welding wires (13, 32) or additional materials extends beneath the burner body (27) into the centre of the welding process.
