Method of retouching metal parts

A welding tool for TIG arc welding, plasma welding or laser welding, including a welding head carrying a refractory electrode and surrounded by a skirt. The skirt is releasably fastened on the welding head and has a front portion which extends forwards and is shaped to surround a weld head with clearance over a predetermined length. The skirt is made by molding or thermoforming a composite material made of at least two layers of ceramic fibers which are bonded together by an elastomer that withstands high temperatures.
