Welding Joints
	Advanced 4 pts	Proficient 3 pts	Basic 2 pts	Below Basic 1 pts	Total Points (N/A)
Weld width and height: 100 % Uniform width and thickness throughout the entire length of each weld.	Advanced Bead is uniform width all along the length of each welld. Has a smooth appearance	Proficient Bead maintains width and length. Shows some small blemishes along the weld	Basic Not a uniform thickness through out the weld. Thickness goes to extremes	Below Basic Weld is cut off in places, not uniform along the weld. Shows bare spots	Total Points
Appearance 100 % Smooth with uniform dense ripples, doesn’t show the bead traveling to fast or slow	Advanced Weld shows a constant speed and uniformity the entire length	Proficient Weld shows a constant speed with some blemishes that are minimal	Basic Weld shows definite areas of speeding up and slowing down. Ripples tend to be coarse	Below Basic Weld has been done to fast or to slow. Weld is not complete	Total Points
Edge of bead 100 % Good fusion, no overlapping or undercutting	Advanced Sides and edges are smooth blending into each weld. Undercutting is kept to a minimum, Weld does not float on surface	Proficient Moderately smooth blending. Undercutting and float are present. Stength of the weld is still strong	Basic Float and undercut are very apartent. Weld lacks strength and flow	Below Basic Metal is burned through. Weld has no connection to metal,	Total Points
Beginning and ending full size 100 % Crater well filled	Advanced End of each weld is complete, the line doesn't taper off	Proficient Weld ending is full but shows some tapering and a craterpresent	Basic Crater distinctly present at the end of the bead.	Below Basic Metal is burned through at the end	Total Points
Surrounding Plate 10 % Welding surface free of spatter	Advanced Spatter is kept to a minuimum.	Proficient Some spatter is present but not displeasing	Basic Spatter is in large amounts	Below Basic Spatter takes away from the integrity of the weld.	Total Points
