Manufactured by G.A.L. Gage Co., the Decimal Fillet Weld Set (8-Piece) (~ With Markings on ONE Side ~) is a specialized precision inspection tool engineered for accurate measurement of small fillet weld leg and throat sizes in decimal inches. Ranging from .050" to .200", this fan-style multi-blade stainless steel set allows quality control inspectors, welders, and fabricators to quickly and precisely verify small weld dimensions in aerospace, precision sheet metal, and critical industrial applications.
Precision welding requires exact dimensional verification, especially for smaller fillet sizes where standard fractional gauges may lack sufficient granularity. The Decimal Fillet Weld Set features 8 distinct stainless steel blades with clear decimal inch markings on one side. Secured by a heavy-duty pivoting thumb nut, the blades fan out smoothly for rapid comparison against the weld leg and throat. Each blade is precision-machined to ensure reliable, repeatable inspection results in tight spaces and demanding shop environments.

Features
- Decimal Inch Precision: Specifically calibrated for precise decimal measurements starting from .050" up to .200"
- Dual Measurement Capabilities: Accurately checks both fillet leg size and fillet throat size
- Single-Side Markings: Features clear, high-contrast size markings on one side for rapid visual identification during inspection
- Compact Fan-Style Design: Blades fan out effortlessly for quick selection and fold compactly into a pocket-sized toolset
- Heavy-Duty Stainless Steel Construction: Fabricated from corrosion-resistant premium stainless steel to resist wear and harsh shop conditions
- Secure Locking Thumb Nut: Allows blades to be held firmly in position during measurement or folded neatly for storage
Applications
- Aerospace and Defense Manufacturing: Inspecting precision small-scale fillet welds on structural components, brackets, and sheet assemblies
- Precision Sheet Metal and Fabrication: Verifying weld leg and throat dimensions on thin-gauge metals and specialized enclosures.
- Petrochemical and Piping Maintenance: Checking small auxiliary connection welds and socket weld fittings where fine decimal tolerances are required.
- Quality Control (QC) and Inspection: Essential precision toolkit component for Certified Welding Inspectors (CWIs) handling fine-tolerance fabrication projects

How to Use
- Select the Appropriate Blade: Fan out the gauge set and select the blade corresponding to the required decimal size specified on the engineering blueprint.
- 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 weld to ensure theoretical throat thickness conforms to specifications.
- Evaluate Fit: A smooth, flush fit confirms correct weld sizing; gaps or interference indicate undersized or oversized welds requiring corrective action
