Question

Two ¼" fillet welds, two inches long. In engineering, what is the purpose of a fillet weld?

a) To increase weight
b) To enhance aesthetics
c) To join two pieces of metal at an angle
d) To join two pieces of metal at a right angle

Answer 1

A fillet weld is used in engineering to join two pieces of metal at a right angle, not to increase weight or enhance aesthetics. This type of weld creates a strong and permanent bond, which is essential in construction and manufacturing.

Step-by-step explanation:

A fillet weld is a common type of weld used in engineering and fabrication. It serves the purpose of joining two pieces of metal together, typically at a right angle. The question presents options and identifies that the welds are quarter-inch fillet welds, two inches long. One of the key functions of a fillet weld is to create a strong bond between two sheets or parts of metal that are perpendicular to each other.

Therefore, the correct answer is d) To join two pieces of metal at a right angle. This type of weld is not designed to increase weight or enhance aesthetics, which are options a) and b), respectively. The general application of weld such as the fillet weld involves the utilization of heat to melt the materials along with soldering them, fostering a permanent bond that is crucial in many construction and manufacturing processes.
