WeldGauge
Weld Inspection & EN5817 Eval
$4.99
Measure weld dimensions with your iPhone camera. Supports fillet weld leg/throat sizing, butt weld reinforcement, and pipe fitting lookup per AWS D1.1, ASME & EN ISO 5817
WeldGauge turns your iPhone into a portable weld inspection station. Capture a photo of any weld, calibrate it against a known reference, and measure imperfections directly on-screen — with instant pass/fail evaluation against EN ISO 5817.
WHAT MAKES WELDGAUGE UNIQUE
Unlike generic measurement or photo annotation apps, WeldGauge is purpose-built for welding quality control. It combines calibrated dimensional measurement with built-in welding standards evaluation in a single workflow — something previously only possible with dedicated lab equipment or desktop software.
CAPTURE & IMPORT
• Built-in camera with up to 20× zoom for close-up weld detail
• Import existing photos from your library
• Automatic background removal to isolate the weld profile
• 45° rotation for angled weld orientations
CALIBRATE
• Place any known reference (ruler, gauge block, coin) in the photo
• Draw a calibration line and enter the real-world dimension
• The app calculates a precise pixel-to-millimeter ratio
• Re-calibrate anytime without losing measurements
MEASURE
• Tap to measure linear distances on the calibrated image
• Measure reinforcement height, undercut depth, misalignment, throat thickness, and more
• Pan, zoom, and rotate freely while measuring
• Edge detection overlay highlights weld boundaries automatically
EVALUATE AGAINST EN ISO 5817
• Select the imperfection type (502, 504, 507, 508, 5011, 5213, 512)
• Enter wall thickness and weld width
• Instant evaluation against quality levels B, C, and D
• Clear pass/fail result for each level
• Built-in reference guide with illustrations for every imperfection type
PIPE FITTINGS LIBRARY
• Searchable database of standard pipe fittings (elbows, tees, reducers, caps)
• Dimensions and specifications for quick field reference
• Filter by type and nominal size
PROJECT MANAGEMENT
• Organize inspections into projects with metadata
• Store weld number, location, welder ID, and notes
• Multiple measurements per project
• All data persists locally — nothing is uploaded
EXPORT & REPORTING
• Export measurement results as structured reports
• Share annotated photos with measurement overlays
• PDF and CSV output for documentation
FULLY OFFLINE & PRIVATE
• Every feature works without an internet connection
• Zero data collection — no analytics, no tracking, no accounts
• All photos and data stay on your device
• Perfect for field inspections in remote locations
WHO IS IT FOR
• Welding inspectors (CWI, IWI, CSWIP)
• Quality control engineers
• Fabrication shop supervisors
• Welding students and trainees
• Anyone who needs quick, standards-based weld evaluation on site
WeldGauge replaces the workflow of "take a photo → transfer to PC → open CAD software → measure → look up the standard → calculate." Now it's one app, one device, one minute.
