Manufactured by G.A.L. Gage Co., the Cat # 82 8-Piece Fillet Weld Set is a professional-grade precision inspection kit engineered for accurate measurement of large fillet weld leg and throat sizes ranging from 2-1/8" to 3" in 1/8" increments. Featuring a robust fan-style multi-blade assembly secured by a heavy-duty retaining thumb nut, this tool enables welding inspectors, quality control (QC) personnel, and heavy fabricators to verify critical weld dimensions quickly and reliably in shop or field environments.
Ensuring structural integrity in large-scale fabrication requires precise dimensional verification. The Cat # 82 Fillet Weld Set provides a comprehensive range of stainless steel gauge blades that swing smoothly into position for rapid comparison against large welds. Each individual blade is permanently laser-etched with its exact size designation, ensuring long-lasting legibility under severe industrial conditions. The set covers larger structural welding requirements beyond standard gauges, making it indispensable for heavy infrastructure, bridge building, and industrial plant construction.

Features
- Large-Scale Weld Inspection: Specifically designed for measuring heavy fillet weld leg and throat sizes from 2-1/8" to 3"
- Precision 1/8" Increments: 8 distinct blades provide fine-grained step measurements for precise conformance checks
- Dual Measurement Capabilities: Accurately checks both fillet leg size and fillet throat size (theoretical and actual)
- Heavy-Duty Stainless Steel Construction: Fabricated from premium-grade stainless steel to resist rust, wear, and corrosion in harsh environments
- Fan-Style Portable Design: Blades fan out effortlessly for quick selection and fold compactly into a pocket-sized toolset
- Permanent Laser-Etched Markings: High-contrast size designations withstand heavy industrial handling and cleaning solvents
Applications
- Heavy Structural Steel Fabrication: Verifying large fillet weld dimensions on massive beams, columns, crane runways, and heavy structural connections
- Bridge & Infrastructure Construction: Ensuring strict compliance with American Welding Society (AWS) and civil engineering codes for large-scale steel structures
- Petrochemical & Power Plant Construction: Inspecting critical heavy-duty welds on pressure vessel supports, large storage tanks, and structural skids
- Shipbuilding & Marine Engineering: Inspecting heavy hull framing, structural bulkheads, and offshore platform assemblies
- Quality Control (QC) & Independent Inspection: Essential high-capacity toolkit component for Certified Welding Inspectors (CWIs) handling heavy industrial projects

How to Use
- Select the Appropriate Blade: Fan out the gauge set and select the blade matching the engineering blueprint specification for the large fillet weld
- Check Fillet Leg Size: Place the straight edge of the blade flush against one member of the joint and the curved edge against the weld toe/face to verify leg dimensions
- Check Fillet Throat Size: Position the designated throat-checking edge against the joint to ensure the throat thickness meets required design standards
- Evaluate Fit: A smooth, flush fit confirms proper weld sizing; gaps or interference indicate under-sizing or excessive convexity/concavity requiring rework
