Flux-Cored Wire Selection - Lincoln Electric

For many welding appliions like vertical-up welding, flat welding, welding over galvanized, or welding hard-to-weld steels, a flux-cored wire can do it better and faster. Although gas metal arc welding (GMAW) with a solid mild steel wire is popular, easy-to-use, and effective for many appliions, it does have limitations and drawbacks.

4140?

Apr 23, 2010· Welding direct hardening materials with traditional short circuit mig and hard wire is not a low hydrogen process. It can be done at 600-900F to slow the "weld quench" with a controlled cool down to prevent "secondary hardening", but if it fails in service all you need to find out if it was a "quick and dirty MIG" weld is a brush and some water.
