1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 10 NPH FLUX COATED MMA ELECTRODE FOR PRE-HEATING AWKWARD WELD JOINT CONFIGURATIONS DATA SHEET NO. 155 SPECIFICATION CLASSIFICATION NO NATIONAL SPECIFICATIONS PRODUCT DESCRIPTION The extruded flux coating is a blend of thermally stable metal oxides combined with metals which have a relatively low free energy of oxide formation that results in pre-heating arc that does not melt the base material. WELDING FEATURES OF THE ELECTRODE Opposed to normal electrodes, a large length arc is established which is stable both AC and DC. The energy dissipated into the base material causes it to gradually warm without causing it to melt. Electrode consumption per time unit of usage compared to welding electrodes is very low. APPLICATIONS Used solely for the purpose of applying moderate pre-heat to stresses welding praparations when circumstances or location provent conventional methods being used. For maximum benefit, pre-heat not only the weld preparation but also adjacent areas. WELD METAL ANALYSIS COMPOSITION % BY Wt.
