Problem:

Perform a vertical "T" weld keeping distortion to a minimum.

Materials:
  2 -  1/4" x  2" x 4"  metal plates.
  Appropriate electrode(s) selected from those in the welding booth.
  1 – Fire Brick to rest metal against.

Directions:
  • Prepare the metal, grinding, cleaning, etc.
  • Secure the metal.
  • Select electrode from those in welding booth and set welder amperage.
  • Have the Contest official record the type of rod and welder amperage
  • Position metal as shown.
  •  Tack as needed.
  • Perform weld, welding on one side only.
  • Using your pliers, hand your weld to a contest official.  They will cool your metal.
  •  Put contestant number on the back side of the welded plates and on this sheet.
  • Turn in work and this sheet.
