Welding Wire China  scrapped:
Structural Carbon Steel Welding Electrode , low hydrogen electrodes and heat-resistant steel, low temperature steel electrodes, cored wires rust serious (drug skin core welding with curved electrode method revealed), drug skin serious damp surface "white flowers" serious occurrence of drug the skin adhesion the knot cake, or drug skin chalking off (such as cast iron electrode) transition alloying elements rely on drug skin electrodes found to the drug skin peeling off, that such electrodes can not be used, precious core welding, such as stainless steel core wire, nickel base metal core, can still get rid of drug skin, re-extrusion coating.
