Evaluation should include

• performing a visual inspection of tacks and welds for defects and discontinuities (e.g., undercut, slag inclusion, overlap)
• planning necessary steps to correct defects, if possible, or prevent similar outcomes.

Process/Skill Questions:

• Why is tack size important?
• What is crater crack and how is it prevented?
• What causes an overlap in welds?
• What are the side effects of slag inclusions, and how are they prevented?
• How are slag inclusions removed from a weld?
