<p>A method and an arrangement for such underwater arc welding in which the welding electrode (32) is placed onto the zone (22) to be welded in lying position, the said electrode being covered with a shield structure (33) and ignited so that, when the burning goes on, it produces the desired weld at the zone (22) to be welded. According to the invention, a mantel (23) is used as the shield structure, which mantle comprises an inner burning layer (33) made of a readily burning, preferably resilient material, by means of which the electrode (32) is covered, and an outer protective layer (23), preferably made of a flexible material, by means of which the burning layer (33) is covered, and fastening means (34), by which the mantel (23) is fixed firmly and tightly in position. The fire gases produced during the burning of the electrode (32) and of the burning layer (33) prevent penetration of water to the electrode (32).</p> |
