Agglomerated, alloyed flux used for hardfacing purposes in combination with low alloy OE-S1 wire electrodes. It finds application in hard facing of couplings, piston rod ends, earth moving equipment, rolls, mills, etc. The alloying effect of the flux depends, to a large degree, on the weld parameters chosen. For instance, optimum welding parameters for 4 mm wire electrode are about 600 A, 32 V, 50 cm/min. welding speed.
