Fabrication Tools - Angles Lengths Gaps & Fixturing
Tools and short usage notes for precise metal fabrication layout and setup
Layout & Measuring
Tape Measure & Steel Rule
Quick linear measurement and marking; use steel rule for short, accurate runs.
- Tip: Lock tape and double-check zero at ends.
Combination Square
Set/verify 90° and measure/mark offsets, depth, and centerlines.
Steel Straightedge / Flat Bar
Reference edge for scribing, checking flatness, and butting pieces together.
Center Punch & Transfer Punch
Mark holes and transfer bolt/hole centers after layout.
Scribe & Soapstone
Durable, visible marks on metal; soapstone wipes off when needed.
Feeler Gauge Set
Measure and set precise gaps (e.g., root gap for weld joints).
- Range: common 0.05–1.00 mm (or imperial).
Angle Tools
Digital Angle Finder / Protractor
Fast, accurate measurement and transfer of angles; useful for bevels and miter cuts.
Bevel Gauge / Sliding T-bevel
Set and copy angles between workpieces; lock in place for marking or cutting.
Magnetic Angle Clamps
Hold pieces at common angles (30°, 45°, 60°, 90°) quickly during tack welding.
- Note: Use multiple magnets for heavier sections.
Protractor Head / Combination Protractor
Heavy-duty protractor for layout on large plates or fabrications.
Weld Gaps & Fit-up
Feeler Gauges
Set root gaps precisely for groove welds and fillets.
Gap Blocks / Gauge Blocks
Hardened blocks in set thicknesses for repeatable gap/stand-off settings.
Weld Gauge (Fillet & Weld Size Gauge)
Measure throat size, leg length, convexity, and undercut to confirm weld specs.
Shim Stock / Copper Shims
Thin shims to fine-tune spacing; copper is weld-friendly for tack spacing near joints.
Spacer Pins / Rods
Temporary spacers placed between butted tubes/plates during tacking to hold uniform gap.
Clamps & Fixturing
F-clamps, C-clamps & Vise Grips
Basic heavy clamping to hold pieces for tack and welds; use protectors to avoid marring.
Welding Magnets & Angle Brackets
Speedy alignment and hold for small to medium parts at common angles.
Welding Table with T-slots
Flat reference surface with fixture points for repeatable setups and squaring.
Fixture Blocks & Locating Pins
Custom blocks and pins for repeatable positioning in jigs and fixtures.
Turntables / Positioners
Rotate/position assemblies for continuous welding or easier access while maintaining alignment.
Final Checks & QA Tools
Digital Calipers
Measure thickness, gaps, and small dimensions accurately.
Weld Size & Fillet Gauge
Confirm fillet leg lengths and throat dimensions to spec.
Square & Straightedge Re-check
Ensure assemblies remain square after tack and final welds (heat can distort).
Contour / Profile Gauges
Check formed profiles and mating surfaces for correct fit-up.
