Argon-arc welding universal mills for welding of tube billet from copper and copper alloys, steel, aluminum
These mills are intended for manufacturing of the tubes by method of continuous casting and argon-arc welding by tungsten electrode of thin-walled tube billet rolled up in coils with following drawing at drum type mills without intermediate annealing between passes. Diameter of finished tubes is from 2 up to 20 mm with wall thickness from 0.15 up to 0.8 mm.
