Abstract:

Twelve austenitic electrodes were evaluated for use as wet welding electrodes. The type electrodes investigated were Inco-Weld A and two modifications, INCONEL Welding Electrodes 112 and 182 and a semi-commercial stainless electrode designated R-142 and five modifications. E6013 was used as a standard. The welds were bead-on-plate and three bead multipass deposits. Most welds were made automatically in 3-12 NaCl solution with gravity fed electrodes and controlled travel speed. Direct current, straight polarity and the drag technique were used. The evaluation was based on operability, porosity, crack resistance and undercut. The factors considered for operability were bead appearance, slag removal, arc stability and ease of operation. The effect of travel speed, current and coating thickness on bead appearance and porosity were determined. The coating thickness was also related to depth of cup.
