Welcome to Extreme Couponing: Welder Edition with Kevin Roy. In the welding trade, your qualification must match the material, position, and process you’ll perform on the job. In this video, Kevin walks through the most common test coupons, how they’re processed (bend tests, X-ray, macro-etch, wedges), and where each qualification applies—from structural steel to sheet metal, pressure/pipe and handrails.

What you’ll learn

• Why qualifying to the right position/process matters for employability and site access
• S-Class (Structural) plate with backing: root openings, positions, materials & processes
• Marine Annex (CJP): weld face, back-gouge, tie-in; for steel & stainless
• Fillet Weld Test: any position, any process; T-, lap-, and corner joints; fracture checks
• T-Class (Open Root) Plate & Pipe: already in W47.1; 6G as an “all positions” qualifier*
• Sheet Metal Test: ≤3 mm / 10-gauge and under; autobody & ducting applications
• Handrail Qualification (butt & coped T): safety-critical, position & procedure are key
• How CWB testing helps uphold quality and safety standards across industries

*Note: 6G typically qualifies for all pipe positions—always confirm exact scope with your code/standard and employer requirements.
