G.A.L. Gage Co. Weld Measuring Fillets

Explore our precision collection of G.A.L. Gage Co. Fillet Weld Measuring Gauges, engineered for fast, accurate inspection and quality control of fillet welds, socket welds, and joint profiles across structural, piping, shipbuilding, and heavy industrial applications.

Designed for professional welding inspectors, quality assurance engineers, and fabricators, these robust stainless steel instruments provide exact measurements of leg length, throat thickness, contour profiles, and internal alignments. Ensuring proper weld dimensions prevents structural failures, reduces costly rework, and guarantees strict compliance with international AWS, ASME, and structural welding codes.

Key Applications & Measurement Capabilities

• Internal Pipe Alignment & Joint Fit-Up Verification: Accurately measure internal pipe misalignment (High-Low), wall thickness, and joint fit-up gaps before and after welding using the G.A.L. Gage Co. Cat # 1 HI-LO Welding Gauge (GAL-1).
• Adjustable & Complex Geometry Measurement: Verify leg dimensions and throat thicknesses on skewed members, T-joints, and custom joint angles with high operational flexibility using the G.A.L. Gage Co. Cat # 3 Adjustable Fillet Weld Gauge (GAL-3).
• Comprehensive Multi-Parameter & Cam-Style Inspection: Verify preparation angles (up to 37-1/2°), excess weld metal (capping size), undercut depth, pitting depth, and fillet dimensions using versatile cam instruments such as the G.A.L. Gage Co. Cat # 4 Bridge Cam Gauge (GAL-4) and the G.A.L. Gage Co. Cat # 4a Pocket Bridge Cam Gauge (GAL-4a).
• Automatic Butt & Fillet Weld Sizing: Quickly calibrate and determine fillet and butt weld dimensions on-site without complex calculations using the G.A.L. Gage Co. Cat # 6 Automatic Weld Size AWS Type Gauge (GAL-6).
• Standard Fillet Leg Length & Throat Verification: Measure standard equal and unequal fillet weld leg lengths and throat dimensions using robust multi-blade sets covering fractional inch and metric ranges with the G.A.L. Gage Co. Cat # 8 Fillet Weld Gauge 7-Piece Set (GAL-8).
• High-Resolution & Fine Increment Inspection: Inspect small-scale fillet welds and micro-tolerances required in high-precision manufacturing sectors such as aerospace and medical equipment using the G.A.L. Gage Co. Cat # 8d 12-Piece Fillet Weld Set (GAL-d) and the G.A.L. Gage Co. Cat # Decimal Fillet Weld Set 8-Piece (GAL-Decimal).
