Question

the process of creating metal structures by cutting, bending, and welding
a. arc tracking
b. hardfacing
c. fabrication
d. duty cycle
a method of overlay welding used to protect surfaces from wear
a robotic welding feature that follows the path of a weld joint

Explanation:

1. For "the process of creating metal structures by cutting, bending, and welding", the term is fabrication (c) as fabrication involves creating metal structures through these processes.
2. For "a method of overlay welding used to protect surfaces from wear", the term is hardfacing (b) as hardfacing is an overlay welding technique for wear protection.
3. For "a robotic welding feature that follows the path of a weld joint", the term is arc tracking (a) as arc tracking is a robotic welding feature for following weld joint paths.

Answer:

1. "the process of creating metal structures by cutting, bending, and welding" - c. fabrication
2. "a method of overlay welding used to protect surfaces from wear" - b. hardfacing
3. "a robotic welding feature that follows the path of a weld joint" - a. arc tracking
