Some community and technical colleges offer individual continuing education courses in welding inspection, often designed to prepare students for professional welding inspector certification through the American Welding Society. Courses in welding inspection are often available through certificate or associate degree programs in welding technology. In addition to hands-on shop training, these programs may include a supervised work experience component.
Here are some common concepts taught in welding inspection courses:
- Types of welding
- Shielded metal
- Materials and equipment
- Industry/testing standards
List of Common Courses
Introduction to Welding Course
An introductory course in welding usually focuses on welding theory and standards of safety. It also allows students to become familiar with cutting and welding equipment, as well as basic welding procedures. Course topics include using shielded metal arc welding to create stringer beads, T-joints and butt welds. This course is recommended, and sometimes required, before students continue their welding technology training.
Arc Welding Course
Instruction in arc welding can be offered in an advanced welding course or as a separate course that concentrates on the different types of arc welding, such as shielded metal, gas tungsten, gas metal and flux cored. Topics include welding positions, such as flat, vertical, horizontal and overhead; welding materials, such as aluminum, carbon and stainless steel; and welding equipment considerations, such as appropriate heat levels and AC/DC currents.
Pipe Welding Course
Pipe welding can be taught on both basic and advanced levels. Basic level courses often provide students with practice opportunities to make welds on flat plate material before moving on to pipe welds. More advanced courses continue pipe welding training while preparing students for the American Society of Mechanical Engineers (ASME) and American Welding Society (AWS) pipe welding certification exams.
Blueprint Reading Course
Reading welding blueprint drawings is a required skill for all welders and welding inspectors. Blueprint courses usually begin with instruction in basic blueprint sketching techniques but also include detailed views, assembly sketches and projections. Additionally, lectures can address common welding symbols, vocabulary, dimensions and industry standards.
Welding Inspection Course
Welding inspection can be offered as a basic or advanced course. It includes instruction in various types of destructive and nondestructive testing, inspection methods and equipment. Lectures introduce testing methods involving liquid penetrants, x-rays, magnetic particles, ultrasonics and eddy currents, as well as the safety measures required for each. Students also become familiar with the testing standards of the American Society for Nondestructive Testing, the ASME and the AWS.
