PCT No. PCT/EP92/01381 Sec. 371 Date Feb. 22, 1994 Sec. 102(e) Date Feb. 22, 1994 PCT Filed Jun. 18, 1992 PCT Pub. No. WO92/22399 PCT Pub. Date Dec. 23, 1992.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.
