WLD 201 - Gas Metal Arc II
This course covers the application of gas metal arc welding theory to non-ferrous materials and their alloys. Different modes of metal transfer are addressed.
Upon successful completion of this course, students should be able to:
Show proper GMAW equipment set-up.
Demonstrate threading GMAW wire.
State how to set appropriate gas flow rate and current.
Describe the various methods of metal transfer.
Explain the effect of slope and inductance in gas metal arc welding.
Perform welds in all positions using the short-circuiting metal transfer method.
Weld in the IF, 2F and IG positions using the globular metal transfer method.
Perform welds in the IF and IG positions using the axial spray metal transfer method.
