Assignments and Methods of Evaluating Student Progress:
1. Typical Assignment
Properly set up and adjust the machine for the FCAW dual shield process, select the
appropriate settings (0.045 inch diameter ER 211 wire), select two pieces of mild steel sheet
(5/8 in. thick) and perform beveled butt weld, waved beats welds in the horizontal position.
a. Obtain 5/8 in. plate, oxyacetylene cut and bevel along the longest side at 30 degree angle
two 7 in. by 4 in. plates
b. Set up the wire feeder with ER211 Lincoln flux core wire (0.045 diameter) at the 110
inch/minute speed, and a constant voltage of 20 volts
c. Set up the proper CO2 gas flow according to the appropriate chart
d. Set the power supply on DC straight polarity
e. Set up and tack plates at each end
f. Make welds in vertical up 3G position
g. Chip the slag from the weld brush and inspect for each pass
h. Submit the welds for instructor inspection for each welding pass
i. Practice until will produce consistently sound welds with both type of electrodes
2. Methods of Evaluating Student Progress
a. Class participation
b. Laboratory assignments and projects.
c. Student finding laboratory written reports
d. Final examination: performance test
