Course name: Basic Gas Metal Arc Welding | Credit(s) or Grade Level: 10-12 | ||||
Academic Standards: https://dpi.wi.gov/sites/default/files/imce/cte/pdf/te_standards.pdf | Prerequisite(s): Welding I&II | ||||
Course Description: Students in this course work to develop manipulative skills on all types of joints in the flat, horizontal and vertical up and down position using short circuiting transfer. Students will perform gas metal arc welding techniques using 1/8” – ½” structural fabricated parts, as per AWS code standards. Emphasis is placed on operating gas metal arc welding equipment in a safe manner and determine machine set-up for metal thickness, wire size and speed. | |||||
