Assignments and Methods of Evaluating Student Progress:
1. Typical Assignments
Properly set up and adjust the SMAW machine, select the appropriate settings (1/8 inch
diameter electrodes), select two pieces of mild steel sheet (5/16 in. thick) and perform an
overlap, stringer beats welds in the flat position:
a. Obtain 5/16 in. plate and oxyacetylene cut two 12 in. by 4 in. plates
b. Obtain 6010 and 7018 electrodes of the necessary quantity
c. Set the power supply on DC reverse polarity (90 to 105 amperes for 6010 and 110 to 130
amperes for 7018)
d. Set up and tack plates at each end
e. Make welds using a trailing angle of 70 degree in 1G position
f. Chip the slag from the weld brush and inspect
g. Submit the welds for instructor inspection
h. Practice until will produce consistently sound welds with both type of electrodes
2. Methods of Evaluating Student Progress
