Welding  Rubric

  Master Advanced Proficient Basic Does not meet expectations
Weld Height & Width Weld height, width
100% Uniform width and thickness throughout the entire length of each weld.
Bead is uniform width all along the length of each weld. Has a smooth appearance  Bead maintains width and length. Shows some small blemishes along the weld Not a uniform thickness through out the weld. Thickness goes to extremes Weld is cut off in places, not uniform along the weld. Shows bare spots
Appearance 100% Smooth with uniform dense ripples, doesn’t show the bead traveling to fast or slow  Weld shows a constant speed and uniformity the entire length Weld shows a constant speed with some blemishes that are minimal Weld shows definite areas of speeding up and slowing down. Ripples tend to be coarse Weld has been done to fast or to slow. Weld is not complete
Face of Bead 100% Convex, free of voids and high spots, shows uniformity throughout the bead  Has a nice rounded look. Is not overly high, or low. Bead covers a wide area of each weld. Bead is well rounded, mostly uniform over the length of the weld. Shows some high spots / low spots Bead shows many high/ low area's. Total lack of uniformity throughout the weld Weld does not blend into one single bead.
Edge of Bead 100% Good fusion, no overlapping or undercutting  Toes and edges are smooth complete fusion into each weld. Undercutting is kept to a minimum, Weld does not float on surface Moderately smooth fusion. Undercutting /overlap are present. Strength of the weld is still strong Overlap and undercut are very apparent. Weld lacks strength and flow Metal is burned through/ Weld has no connection to metal,
Beginning & Ending of Bead 100% Crater well filled  End of each weld is complete, the line doesn't taper off  Weld ending is full but shows some tapering and a crater present Crater distinctly present at the end of the bead. Metal is burned through at the end
Surrounding Plate 100% Welding surface free of spatter  Spatter is kept to a minimum.  Some spatter is present but not displeasing Spatter is in large amounts Spatter takes away from the integrity of the weld.
Penetration 100% Complete without burn through Weld penetrates deep into the metal and adds strength and fusion to the edges and depth. Weld penetrates but does not re surface through the bottom of a full penetration joint welds/weld penetrates when it should not Weld is uneven in depth, lacks uniformity along weld length. Weld floats on top of the metal. Has no strength
