GMAW 4G Assessment
	Poor 5 pts	Fair 10 pts	Good 15 pts	Excellent 20 pts
Penetration	Poor weld/filler metal is on top of base metal, or burn through at bottom of base metal.	Fair shows evidence of lack of penetration.	Good shows evidence of good penetration in most of the root weld.	Excellent Weld bead has sufficient buildup, and no burn trough with consistent weld penetration.
Width of Bead	Poor Width of weld bead varies 1/2	Fair Width of bead weld over 3/8	Good Width of weld bead varies betweeen 1/4 and more	Excellent Width of weld bead is conistant to the 1/4th requierment.
Height of bead	Poor Not consistent and very uneven. Lots of Highs and lows.	Fair 2 - 3 sections of weld bead too high or too low.	Good 1 section or of weld bead too high or too low.	Excellent weld bead is with in the standard 1/8th hight or less
Apperance	Poor Ripples uneven and rough. Abundance of porosity, undercut, under fill, cold roll, or other.	Fair Most of the weld is rough and has uneven ripples. Most of the weld has one or all of these items present: Valleys porosity, undercut, under fill, cold roll, present.	Good Some of the weld is rough and has uneven ripples. But is consistent and has little to none of the following: Valleys porosity, undercut, under fill, cold roll, present	Excellent Weld is smooth and ripples are evenly spaced. None of the following are present: Valleys porosity, undercut, under fill, cold roll, present
Instructions/Dimention	Poor Name, Date, Fit up, and plate dimensions are None existent or are not with in provided instructions. or used the wrong size plate, or welded in wrong position, poor fit up. Stagger is incorect, bead sequence incorect	Fair Name, Date, Fit up, and plate dimensions are Name and date are not in the proper location and plate dimentions are not within 1/16th of the parameters Fit up needs work not level and has a gap. Stagger has some variance over run.	Good Name, Date, Fit up, and plate dimensions: Fit up is with in a 1/16 of the parameters provided, level but minimal gap. Name and date are not on proper location Stagger is correct	Excellent Name, Date, Fit up, and plate dimensions: Are all exact to the instructions and dimensions provided Stagger is correct
