ONE INCH VEE GROOVE 3G

Technique: The Instructor will provide you with 2 test coupons and 1 backing strip follow directions to assemble the test joint and place in the test position for welding.

Weld the first pass and wait until the Welding Inspector checks the weld before continuing.

Continue welding until the joint is filled with weld and the cover pass is completed. The Welding Inspector will cut two bend test specimens from the completed weld test coupon. Grind the cover pass and backing bar flush and break all sharp corners. The Inspector will supervise the bend and interpret the results.

Remember:

You may use hand tools or power tools to clean each pass.

You should check your heat setting by running a practice bead if you are not familiar with the welding machine.

There is no time limit on the test.

Be careful not to grind to much of the test specimens, have the inspector check if you are unsure.

The cover pass should not be over 1/8 high (size of rod without flux) or 1/8 over the side of the original bevel
