Cored Wire Welding
The flux-cored electrode is a continuous,
tubular electrode wire, with a sheath of low carbon, mild steel and
core containing deoxidizers, slag formers
and arc stabilizers in powder form. Both strip and core materials
are carefully monitored to conform with
rigorous specifications. Automatic controls during production pro-
vide a uniform, high quality product.
Flux-cored wires are specifically designed to weld mild steel using
either CO2 gas
or Argon-Co2 gas mixtures.
Flux-cored
arc welding offers many inherent advantages over stick electrode welding. Higher
deposition rates
(typically double) and increased duty cycles (no electrode changing) mean savings
in labor costs. The deeper
penetration achieved with cored wire also permits less joint preparation, yet
provides quality welds free
from lack of fusion and slag entrapment. Also flux-cored wire welding is easy
to learn.
