Oxy-fuel Welding: Rod Beads
	Unacceptable 0.5 pts	Needs Improvement 1 pts	Acceptable 1.5 pts	Very good 2 pts
Penetration	Unacceptable filler metal is on top of base metal, or burn through an bottom of base metal. Hole(s) in base metal	Needs Improvement shows evidence of fair penetration in some of the weld.	Acceptable shows evidence of good penetration in most of the weld.	Very good Weld bead has sufficient buildup, and no burn-trough
Width of Bead	Unacceptable Width of weld is very inconsistent	Needs Improvement Width of bead weld varies in 2-3 spots, creating a fairly inconsistent weld.	Acceptable Width of weld bead varies in 1-2 spots.	Very good Width of weld bead hardly varies. It is a very uniform weld.
Height of bead	Unacceptable Not consistent and very uneven.	Needs Improvement 2 - 3 sections of weld bead too high or too low.	Acceptable 1 section or of weld bead too high or too low.	Very good weld bead is higher than the original height of the metal. Height of the weld is consistent throughout the weld.
Apperance	Unacceptable ripples uneven and rough.	Needs Improvement Most of the weld is rough and has uneven ripples.	Acceptable Some of the weld is rough and has uneven ripples.	Very good Weld is smooth and ripples are evenly spaced. "Stacking of dimes" is evident
Metal Preparation	Unacceptable The metal was not prepped nor cleaned before or after welding. There are various signs of impurities throughout the weld.	Needs Improvement Evidence of some metal preparation is visible, but more care should have been taken. There are visible impurities on the edges of the weld.	Acceptable The metal has been prepped before and after the weld, but is still dirty. There may be some signs of impurities, but is clear of impurities for the most part.	Very good Metal has been properly cleaned and prepped before the weld as well as after the weld has been completed. There is no evidence of impurities within the weld.
