Course Description
Introduces gas metal arc welding pulse (GMAW-P) and plasma arc cutting (PAC) theory and techniques. Covers basic blueprint reading skills. Explores the essential variables of the gas metal arc welding process. Provides opportunities for welding in all positions. Continues the development of welding techniques for multiple welding positions and joint assemblies. Covers shipyard terminology.
Intended Outcomes for the course
Upon successful completion of the course students should be able to:
- Function safely in a welding shop and a shipyard environment.
- Interpret blueprints to lay out, prepare, and assemble weld joints.
- Use plasma arc cutting and shears according to industry-standard codes.
- Weld advanced joint assemblies using GMAW-P in all positions according to industry-standard codes.
- Assess weld quality through the application of visual examination principles and practices in accordance with industry-standard codes.
- Demonstrate an understanding of shipyard terminology used in maritime welding.
Course Activities and Design
Each concept will be delivered via a combination of lectures and videos followed by practical demonstrations and hands-on application in the welding lab.
Outcome Assessment Strategies
Oral or written examinations, quizzes, written assignments, visual inspection, welding tests and task performance.
