complete solution
The V-shaped head attachment of a combination square can be used to
locate the center of shafts or other round objects
The tool uses a bubble in a glass vial to check level and plumb is a
level
Internal misalignment between two sections of pipe to be welded end-to-end is checked
using a
Hi-Lo gauge
When using a chain to lift or lower weldment parts, always secure the chain fall to an
overhead structural member with an approved
sling
The gap plate of a plate alignment tool can be changed to match the specified
root opening
Although some fit-up tools are often field-fabricated, which of these tools should never
be field-fabricate?
Jack stands
When using a chain clamp to fit pipe, the required gap between the root faces can e
maintained using a
spacer
Which type of fit-up tool is often used to fit flanges and where heavy-duty reforming of
the pipe is required?
Rim clamp
The degree of distortion that happens during welding is directly related to the
stresses generated during welding
Tools such as chain clamps, rim clamps, and strongbacks are used to properly align
and fit weldments and
help prevent distortion
An abundant amount of face reinforcement
reduces the strength of the weld
Open-root joints should have a root opening of
1/16" to 1/8"
A simple welding sequence used to reduce or eliminate distortion is to make short welds
on alternating sides of a joint
The American society of Mechanical Engineers (ASME) updates their entire code every
3 years
On a WPS, when Dc welding process is specified,
the polarity required must also be given
The point at which steel begins to develop brittle properties is when the carbon content
is just below
1.4%
The letter prefix for the AISI classification system for carbon steels indicates the
Manufacturing process
The principal difference between plain-carbon steels and HSLA steels is
