Alloy A Welding Electrode is used for shielded-metal-arc welding of INCOLOY® alloys 800 and 800HT, INCONEL® alloys 600 and 601, and nickel steels.
The weld metal has excellent strength and oxidation resistance at high temperatures and retains impact resistance at cryogenic temperatures.
The electrode is an exceptionally versatile product for dissimilar welding. It can be used on a variety of austenitic and ferritic steels and nickel alloys. Examples are combinations of stainless steels, carbon steels, INCONEL® alloys, INCOLOY® alloys, MONEL® alloys, and copper-nickel alloys.
Because of its versatility, Alloy A Welding Electrode is especially useful for general maintenance welding of equipment exposed to strenuous service conditions.
The electrodes provide excellent operability for groove and fillet welding in the downhand position and the electrodes through 3.2 size diameter are suitable for all position welding.
Power supply: direct current, electrode positive.
