CWB Plate Test

  • 45 minutes per plate – 5/16 maximum leg length
  • 1/8” maximum build up – 1/32” maximum undercut
  • Use run off tabs – wire wheel on grinder allowed
  • No defacing of stamped area – stops and starts must be observed
  • Electrode sizes 3/32”, 1/8”, 5/32” usage – no using any grinders or files for metal removal

Guidelines for passing CWB Welder Test

  • No chipping hammer marks or stray arcs on plate.
  • Fill in the craters at the end of the grove weld.
  • Do not build weld up more than 3mm (1/8”) above the surface of the plate.
  • No grinder, saw blades, files or tools for metal removal are allowed.
  • Ensure that you do not weave up against the square cut plate, always point to the square cut plate when welding to it.
  • You are required to make stop/starts as directed by the CWB representative. Ensue that stop/starts are welded correctly.

Stop/start technique

Using SMAW, restart the arc ahead of the crater, move back to the crater, fill it and continue to weld.

  • Using FCAW, restart in the centre of the weld crater.
  • The second pass must touch the beveled plate.
  • Technique for the fill passes is up to the welder, but it is generally considered easier with less chance of leaving a defect in the weld if stringer passes are used. The vertical position may be an exception.
  • The legs of the fillet weld must not vary in size by more than 1.5mm (1/16”).
  • Fillets size weld is 8mm (5/16”) maximum (this means that you can put on a 5mm (3/16”), 6mm (1/4”) or 8mm (5/16”) fillet weld).
  • If attempting three passes in the root area, make sure enough room is left to fuse the third pass to the backup strip.
