Exam 2025 Questions and Answers
The five basic types of joints are: - ANSWER✔✔-Edge, lap, butt, T, and corner.
T-joints are prone to distortion, though this can be minimized by - ANSWER✔✔-tack
welding at both ends and on both sides.
What is a surfacing weld? - ANSWER✔✔-A weld that is applied to a surface, not
making a joint.
Edge welds are neither groove welds nor fillet welds. - ANSWER✔✔-True
The term "Cladding" refers to - ANSWER✔✔-Creating a corrosion-resistant or heat-
resistant layer.
Fillet welds are used to make: - ANSWER✔✔-Lap, T, and corner joints.
The term "Buttering" refers to: - ANSWER✔✔-Creating buildup intended to provide a
buffer or transition for another surface weld.
, For equal leg convex fillet welds, the measured leg size is the fillet weld size. -
ANSWER✔✔-True
The inclination of axis for overhead groove welds is - ANSWER✔✔-0-80 degrees.
Vertical welding is considered the most difficult to master because gravity can cause the
weld puddle to drip and solidify as "grapes" or "icicles." - ANSWER✔✔-False
5G is a groove weld in a pipe with the axis of the pipe fixed in the overhead position. -
ANSWER✔✔-False
4G is a groove weld in the overhead position. - ANSWER✔✔-True
The _______ position is used to weld from the upper side of the joint, with the
workpiece positioned so that the weld joint and face are horizontal to the ground. -
ANSWER✔✔-flat
On a square butt joint, increasing the root opening increases the - ANSWER✔✔-Depth
of penetration.
One reason for following the rule of "minimum weld metal" is to: - ANSWER✔✔-reduce
stresses and distortion.
Advantages of laser cutting include: - ANSWER✔✔-Narrow kerf width, square edges,
clean and smooth cutting surface, minimum heat-affected zone, minimum distortion,
cutting of metals and non-metals.
