Chapter 12

Restricts flow within the pipe

Excessive root reinforcement should be avoided while welding pipe because

Increase the deposition rate

Feathering the ends of tack welds with a grinder helps to

Weave beads for stainless pipe

For the flux cored arc welding in the 1G rotated position, avoid using

Wear leather seats over your shoes

If the tongue and lace area of your footwear is exposed, you should

True

If you will be welding on zinc or cadmium material for only a few minutes , you may use a metal fume filter T/F ?

Entirely from the flux in the wire core

In FCAW -S , thenshielding gas is generated ___

Voltage that is too high

In the FCAW arc length is too long and causes the wire to melt and fuse to the contact tube

45 degrees to horizontal plane

Multiple inclined (6G) position open root V- groove pipe welds are made with the pipe axis inclined____

Fill the crater

Pay particular attention at the termination of the weld

1/8"

Pipe groove welds should be made with slight reinforcement not to exceed

Low carbon steels

The FCAW process is limited to welding

Methane

The gas that tends to concentrate in and along low areas

0 to 1/8" wide

The welding codes allow the root fave on FCAW open root welds on carbon steel pipe

Dropped slightly, but not more than 10 degrees

To prevent the weld puddle from sagging, the gun work angle can be

Primary disconnect

When preparing the welding machine, verify the location of the
