PowerWeld MG-11 Stainless Steel Fillet Weld Gauge

The PowerWeld MG-11 Stainless Steel Fillet Weld Gauge Set is designed for welders, inspectors, and quality control staff who need a fast, dependable way to check fillet weld size. This weld fillet gauge covers eleven of the most common imperial sizes—1/8″, 3/16″, 1/4″, 5/16″, 3/8″, 7/16″, 1/2″, 5/8″, 3/4″, 7/8″, and 1″—along with their metric equivalents from 3.2–25.4 mm. Each blade is manufactured from 1-1/4″ x 4″ 304 stainless steel, giving good resistance to rust and bending in fabrication shops, structural steel yards, and field work. The MG-11 checks both fillet leg size and throat size on concave or convex welds, helping you confirm that your welds meet drawing or code requirements before the job moves on.

All edges are carefully deburred and all graduations are engraved into the metal for clear, long-lasting markings that remain easy to read after years of use. The compact, folding design keeps the blades protected when not in use and fits easily into a pocket, tool pouch, or inspection kit. Whether you work on boilers, bridges, ships, pressure vessels, or general fabrication, this stainless steel fillet weld gauge set gives you quick, repeatable measurements that support good weld quality and documentation.

• Eleven Fillet Weld Sizes: Checks 1/8″ through 1″ fillet welds (3.2–25.4 mm) for both concave and convex profiles.
• Stainless Steel Blades: 1-1/4″ x 4″ 304 stainless blades resist rust, warping, and everyday shop abuse.
• Leg and Throat Measurement: Designed to verify both fillet leg length and throat size on welded joints.
• Engraved Markings: Imperial increments and metric equivalents are etched into each blade for clarity and durability.
• Deburred for Comfort: Smoothed edges reduce snagging and make the gauge safer and more comfortable to handle.
• Compact Gauge Set: Folding weld gauge set with multiple blades that stores easily in pockets or tool pouches.
• Visual and Dimensional Check: Gives welders a straightforward way to compare the weld to the required size at the joint.

Markets

• Boiler and Pressure Vessel Fabrication Used to verify fillet weld size on critical joints and attachments.
• Bridge and Structural Steel Construction Handy for checking welds on beams, columns, trusses, and stiffeners.
• Shipbuilding and Marine Fabrication Supports weld inspection on hulls, decks, frames, and internal structures.
• Oil, Gas, and Pipeline Work Suitable for assessing fillet welds on supports, brackets, and piping components.
• General Metal Fabrication Shops Everyday weld fillet gauge for checking weld size on frames, brackets, and assemblies.
• Maintenance and Repair Facilities Helps confirm weld size on equipment repairs, modifications, and retrofits.
• Trade Schools and Welding Programs Teaching tool for students learning how to measure fillet weld size correctly.

For welders and inspectors in these markets, the PowerWeld MG-11 fillet weld gauge provides a simple, repeatable way to confirm that weld size matches drawings or code requirements. Structural steel and pressure vessel work often specify fillet leg length and throat thickness, and this welding gauge lets crews check those dimensions directly at the joint instead of guessing by eye. In fabrication and maintenance shops, the MG-11 helps prevent under-sized welds that may fail in service and over-sized welds that waste time and filler metal. Training programs use the same gauge to show students how weld sizes on paper translate to real-world welds, improving understanding of weld symbols and inspection practices. Because it is compact and corrosion resistant, the MG-11 can stay in a pocket or inspection kit every day, ready whenever a fillet weld needs a quick size check.
