II. DESCRIPTION:

Stainless steel Shielded Metal Arc Welding electrode with coating for welding 18/8/Mo stainless steels, AISI 316, 316L and 317 austenitic stainless steel. Austenitic and corrosion-resistant weld deposit of low carbon 19% Cr-12% Ni-2.8% Mo insures against intergranular carbide precipitation, good resistance to pitting corrosion and crevice corrosion by non-oxidizing acids intended applications where service temperatures do not exceed 400ºC. Deposition rate and efficiency (112%) are far better that most other brands in the same class. Slag is practically self-peeling. Handles easily in DC+ or AC current with minimum open-circuit voltage of 70 volts. The finished welds exhibit a slightly concave shape with a good cosmetic appearance which requires little or no post weld dressing. The electrode is ideal for both fillet and butt welding applications.

III. NOTES ON WELDING:

     Prepare all fit the work carefully, cleaning the joints of all foreign material. Use Ac (minimum OCV of 70V) or DC+ current. Proceed with the lowest current possible and a short arc without allowing coating to touch molten pool. Short and intermittent welding is to be preferred to avoid overheating and distortion. Avoid excessive weaving. Electrodes should be coated. Discard exposed core wire by striking or scratch welding in scrap plate until exposed core wire is consumed. Use dry electrodes to prevent blowholes in deposit. If necessary re-dry at 200ºC for two (2) hours before use..
