1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 11 FC-30 SELF GAS SHIELDING FLUX AND METAL FILLED CORED WIRE FOR HARD FACING APPLICATIONS INVOLVING ABRASION AND IMPACT DATA SHEET NO. 159 SPECIFICATION DIN 8555 CLASSIFICATION MF1-300-G PRODUCT DESCRIPTION A tight seamed roll-drawn tubular wire containing an evenly distributed mixture of alloying elements, deoxidants and chemically basic minerals. The minerals dissociate during welding to provide a full protective self-shielding gas which eliminates the need for an external separate shielding gas. WELDING FEATURES OF THE ELECTRODE Suitable for use on DC+ only, the strong forcefull arc is readily controllable and the high silicon content of the alloy lowers the surface tension of the molten weld pool, thus allowing ease of weaving and thus minimal dilution. The deposit contains small percentages of carbon, chromium, silicon and manganese which a crack-free wear resistance deposit with a hardness about 30 HRC, dependent upon parent material dilutions and number of layer. It is particularly suitable for conditions of moderate abrasion and friction, coupled with resistance to heavy impact. APPLICATIONS AND MATERIALS TO BE WELDED Designed for the repair and rebuilding of mild steel and low-alloy ferritic steel components in either the cast or wrought condition, and it is not recommended for manganese steel or cast iron and does not work harden. Specific applications include clutch plates, tractor rollers, steelrope winches, steel shovel pads, gear teeth, sprocket and shafts, rails, couplings, caterpillar tracks, and similar.
