OP 132

OP 132 is an aluminate-basic type flux designed for welding pipes from both sides in one pass. OP 132 is characterised by its excellent current carrying capacity of more than 1500A on the lead wire in multi-wire welding processes. Even at very high local currents the welding process remains stable. The weld seam shows very good wetting, a regular flow and a very broad, flat profile. OP 132 contains specific components which decompose during welding and create protective gases. This gas protection prohibits the access of atmospheric nitrogen to the weld pool and thus guarantees optimum toughness particularly with OE-TIBOR 25 and OE-TIBOR 33 wires when welding from both sides in one pass. OP 132 can also be used in multi-run applications with OE-S2 and NiMo alloyed wires. OP 132 is suitable for applications in sour gas service.
