Flux-cored wire for joint welding

Process

In a shielding gas atmosphere a wire of tubular cross section filled with metallic and non-metallic components is melted off. A rectifier with constant voltage characteristics is the most commonly used source of welding power. Wire feed is effected either with conventional-type integrated or separate wire feed mechanisms. Where bigger wire diameters are to be welded, the use of multi-wheel wire feed driving rolls with toothed wheels has been found highly expedient. In the interest of problem-free welding we recommend the use of water cooled torches at amperages from 200 A upwards.

Advantages
COST REDUCTION
High deposition efficiency

By virtue of higher current densities, faster melt-off times,and a higher current-carrying capacity it is possible to increase efficiency very considerably over that of manual arc welding or solid wire welding. A further particularly important feature of flux-cored wires is that they alloy vertical-up welding at elevated amperage (200 A) in the spray arc range.

Lower filler metal consumption

Because of the good penetration conditions, the general reduction of the weld preparation angle to 40 and the welding of square edged butt joints is possible without risking a lack of fusion.

Shorter welding downtimes

Lower spatter and slag formation eliminates the need for time-consuming weld seam cleaning operations.

RELIABILITY

Flux-cored wires yield a high-grade deposit which is highly resistant to porosity and cracking.
