Using 3⁄32" or 1⁄8" (2.4 or 3.2 mm) E6010 electrodes for the root pass and 3⁄32" or 1⁄8" (2.4 or 3.2 mm) E7018 electrodes for the fill and cover passes, make an open-root V-groove weld oncarbon steel plate in the flat position as indicated.

Criteria for Acceptance:• No arc strikes outside the weld area ____________• Uniform rippled appearance on the bead face ____________• Craters and restarts filled to the full cross section of the weld ____________• Uniform weld size ____________• Acceptable weld profile in accordance with the ASME Boiler and

Pressure Vessel Code ____________• Smooth transition with complete fusion at the toes of the weld ____________• Complete uniform root penetration at least flush with the base

metal to a maximum buildup of 1⁄8" (3.2 mm) ____________• No porosity ____________• No excessive undercut ____________• No inclusions ____________• No cracks ____________ • Acceptable guided bend test results (instructor option) ____________
