A simple welding sequence used to reduce or eliminate distortion is to make short welds
on alternating sides of a joint
on the ends of a joint
on one side and long welds on the other side of a joint
in the middle and long welds on the ends of a joint
Open-root joints should have a root opening of
1/32" to 1/16"
1/16" to 1/8"
1/8" to 1/4"
1/4" to 1/2"
An abundant amount of face reinforcement
stabilizes the weld
is mandated by welding codes
reduces the strength of a weld
is encouraged by codes but wastes weld material
Tools such as chain clamps, rim clamps, and strongbacks are used to properly align and fit weldments and
must be removed immediately after welding ceases
help prevent distortion
ensure that no residual stress can develop
can be used with any base metal, regardless of their composition
Which type of fit-up tool is often used to fit flanges and where heavy-duty reforming of the pipe is required?
rim clamp
cage clamp
strongback
jewel clamp
When using a chain clamp to fit pipe, the required gap between the root faces can be maintained using a
length of iron angle
come-along
cage clamp
spacer
The American Society of Mechanical Engineers (ASME) updates their entire code every
year
2 years
3 years
5 years
On a WPS, when a DC welding process is specified,
tack welding is not allowed
the precise model of the welding machine is also provided
only E6010 electrodes can be used
the polarity required must also be given
The degree of distortion that happens during welding is directly related to the
surrounding air
moisture in the air
position of the weld
stresses generated during welding
