<p>The invention provides a backing strip for welding technology which can be adapted to a large variety of welding methods and applications and is fully effective also in non-horizontal positions. This is obtained in that the more easily meltable forming layer (1) and the less easily meltable base layer (2) of a flexible thread structure of inorganic fibers are connected to form a flat band by binding the threads (10; 20) into a two-layered unitary fabric structure.</p> |
