Final answer:
The specific skills that a welder like Jon must use at a Chevron storage facility involve the ability to use various welding techniques, interpret complex blueprints, and operate modern engineering tools.
Step-by-step explanation:
The question refers to the specific skills that Jon, a welder at a Chevron storage facility, must use to accomplish his job. These skills are defined as the ability to use the techniques, skills, and modern engineering tools necessary for engineering practice. Welding involves the application of heat or pressure to join pieces of metal or thermoplastics through coalescence, which is a sophisticated process requiring a comprehensive understanding of materials science, chemistry, and physics. It also requires proficiency in various welding techniques such as MIG, TIG, and stick welding, and skills in reading and interpreting complex blueprints and diagrams. Furthermore, due to technological advancements, welders must be adept at using modern engineering tools like computer-aided design (CAD) software, welding robots, and new materials.
