WELDING EQUIPMENT AND WELDING METHOD

Title:

WELDING EQUIPMENT AND WELDING METHOD

Document Type and Number:

WIPO Patent Application WO/2009/005174

Kind Code:

A1

Abstract:

Welding equipment includes a torch for irradiating a laser beam (B), wire feeding means (2) for feeding a filler wire (F), and a tracking means (3) for controlling the moving tracks of the torch (1) and the wire feeding means (2) to make a welding line (Y) copy them. The tracking means (3) has a contactor (30A) provided to freely advance/retract for making contact with a joint object (W) resiliently. The joint objects (W) are jointed mutually by touching the contactor (30A) of the tracking means (3) resiliently to the joint object (W) while feeding the filler wire (F) to a welding portion and irradiating that portion with a laser beam (B), thereby moving the torch and the wire feeding means (2) to copy the welding line (Y).
