Question

1/4 inch fillet weld, 2 inches long. In engineering, what is the purpose of a fillet weld?

a) To add weight
b) To join two pieces of metal at a right angle
c) To increase friction
d) To reduce corrosion

Answer 1

The purpose of a fillet weld is to join two pieces of metal, usually at a right angle, to create a strong connection. It plays a significant role in various engineering structures, not intended for weight addition, friction increase, or corrosion reduction.

Step-by-step explanation:

The purpose of a 1/4 inch fillet weld, 2 inches long, in engineering is to join two pieces of metal typically at a right angle. Fillet welds are commonly used in various constructions to create strong, non-load bearing connections. Contrary to the other options, the primary intention of a fillet weld is not to add weight, increase friction, or reduce corrosion.

Welding itself is a fabrication process that joins metal materials using heat, and may employ various fuel sources like gas, electricity, or laser. The process has evolved from the forge welding traditionally done by blacksmiths to more modern methods that ensure stronger and more reliable joints in metal work.
