Module 9

Module Nine (29109-15) introduces the methods and procedures related to SMAW beads and fillet welding. Trainees will learn safety procedures, equipment setup, how to strike an arc, and how to produce weave beads and stringer beads. Hands-on practice and the completion of welding-related Performance Tasks complete the learning process.

Objectives:

Learning Objective 1 • Explain how to prepare for SMAW welding and how to strike an arc.

a. Identify safety practices related to SMAW.

b. Explain how to prepare the area and equipment for welding.

c. Explain how to strike an arc and respond to arc blow.

Learning Objective 2 • Explain how to successfully complete various types of beads and welds.

a. Explain how to properly restart and terminate a weld pass.

b. Describe the technique required to produce stringer beads.

c. Describe the technique required to produce weave and overlapping beads.

d. Describe the techniques required to produce fillet welds in various positions.
