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.
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.
