Welding Fabrication Exam Preparation Guide
Course Introduction
Welding Fabrication is a course designed to introduce students to the fundamental principles and techniques of joining metals through welding processes. The course covers the theory and practical application of various welding methods, including MIG, TIG, and stick welding, as well as cutting, shaping, and assembling metal components. Students will gain hands-on experience with industry-standard tools and safety protocols, interpret technical drawings, and develop the skills needed to fabricate projects to precise specifications. Emphasis is placed on understanding material properties, weld quality inspection, and proper use of equipment to prepare learners for entry-level positions in the welding and metal fabrication industries.
