Assignments and Methods of Evaluating Student Progress:
1. Typical Assignment
Properly set up and adjust the SMAW machine, select the appropriate settings (1/8 in.
diameter electrodes), select two pieces of mild steel sheet (5/8 thick) and perform a butt joint,
wave beats welds in the vertical up position
a. Obtain 5/8 in. plate and oxyacetylene cut and bevel along the longest side at 30 degree
angle two 7 in. by 4 in. plates
b. Obtain 6010 and 7018 electrodes of the necessary quantity and size (1/8 in.)
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 and in the vertical position (make sure that it is
connected to the work connection)
e. Perform a root pass followed by a hot pass using 6010 electrodes
f.
Chip the slag from the weld brush and inspect
g. Perform the rest of the passes as many as necessary with 7018 electrodes
h. Chip the slag from the weld brush and inspect
i.
Submit the welds for instructor inspection
j.
Practice until will produce consistently sound welds
k. Cut two11/2 in. testing specimens across the practiced welds and perform two bending
tests one face up and the second face down
l.
Inspect and discuss the results with your instructor
m. Prepare the test to be sent to the inspection lab for further analysis
2. Methods of Evaluating Student Progress
a. Class participation
b. Laboratory assignments and projects.
c. Student laboratory written reports
d. Final exam: performance test
