Module 6

Module Six (29106-15) introduces trainees to the methods and procedures to produce high-quality welds. Trainees will become familiar with welding codes and provisions, discontinuities, examination practices, and weld procedure testing. Trainees will then complete a visual inspection on a fillet and/or groove weld and complete an inspection report to document the results.

Objectives

Learning Objective 1 • Identify and describe the various code organizations that apply to welding and their basic elements.

a. Identify the various welding code organizations and their sponsoring organizations.

b. Identify and describe the basic provisions of welding codes. Learning Objective

Learning Objective 2 • Identify and describe weld discontinuities and their causes.

a. Identify and describe discontinuities related to porosity and inclusions.

b. Identify and describe discontinuities that result in cracking.

c. Identify and describe discontinuities related to joint penetration, fusion, and undercutting.

d. Identify and describe acceptable and unacceptable weld profiles.

Learning Objective 3 • Describe various non-destructive and destructive weld examination practices.

a. Describe basic visual inspection methods including measuring devices and liquid penetrants.

b. Describe magnetic particle and electromagnetic inspection processes.

c. Describe the radio-graphic and ultrasonic inspection processes.

d. Describe destructive testing processes.

Learning Objective 4 • Describe the welder performance testing process.

a. Describe the qualification of welders by position.

b. Describe welder qualification testing to meet American Welding Society (AWS) and American Society of

Mechanical Engineers (ASME) requirements.

c. Describe the process for completing a weld test.
