Architecture and Construction, Grade 9 - 12, Gas Metal Arc Welding, 2009

1.) Explain safety precautions for the gas metal arc welding (GMAW) process.

2.) Demonstrate techniques for setting up GMAW equipment.

•  Explaining types of metal transfer specific to the GMAW process
•  Selecting filler wire and gas combinations for the GMAW process
•  Adjusting the GMAW machine with various controls and settings
Examples: spray arc, short arc

3.) Demonstrate fillet welds with the GMAW process for carbon steel.

4.) Utilize the GMAW process to demonstrate proper T-joint fillet weld techniques for single and multiple passes, including flat fillet welds in the 1-F position, horizontal fillet welds in the 2-F position, vertical up-and-down fillet welds in the 3-F position, and overhead fillet welds in the 4-F position.

5.) Utilize the GMAW process to demonstrate proper lap-joint fillet weld techniques for single and multiple passes, including flat fillet welds in the 1-F position, horizontal fillet welds in the 2-F position, vertical up-and-down fillet welds in the 3-F position, and overhead fillet welds in the 4-F position.

6.) Utilize the GMAW process to demonstrate proper corner-joint fillet weld techniques for single and multiple passes, including flat fillet welds in the 1-F position, horizontal fillet welds in the 2-F position, vertical up-and-down fillet welds in the 3-F position, and overhead fillet welds in the 4-F position.
