The Paprsky Hi-Lo Weld Check (Metric/Standard) Gauge is a multipurpose pre-weld alignment and inspection tool designed for internal pipe fit-up and wall-thickness measurement. Its sliding body and specialised interior alignment stops allow users to verify pipe alignment and spacing before welding. The gauge helps support correct fit-up and reduce conditions that can contribute to socket-weld cracking. It provides both metric and standard scale readings and includes precision-milled gap stops along with a standard bevel-check function.
Paprsky provides precision welding inspection instruments designed to support accurate fit-up, alignment, and weld-quality checks. The Hi-Lo Weld Check (Metric/Standard) Gauge helps welding professionals verify pipe positioning and gap spacing before welding, supporting improved joint preparation and helping prevent socket-weld cracking.

Key Features
- Metric and Standard Readings: Supports measurements using both millimetre and inch-based scales.
- Internal Alignment Stops: Specialised stops assist with evaluating internal pipe alignment and fit-up.
- Sliding Body Design: Enables the gauge body to be positioned accurately against the outside of the pipe.
- Pipe Wall-Thickness Measurement: Supports inspection of wall thickness during fit-up verification.
- Precision-Milled Gap Stops: Includes 1/16 in. and 3/32 in. stops for checking pre-set gap spacing.
Usage Instructions
- Loosen the screw and insert the gauge feet into the pipe gap.
- Rotate the gauge 90° so that it spans both pipe walls.
- Pull the gauge back until the interior alignment stops contact the inside of the pipe.
- Slide the gauge body against the exterior pipe surface and tighten the screw.
- Remove the gauge and read the measurement from the graduated scales.
Applications
- Oil & Gas: Pre-weld pipe fit-up inspection for high-pressure piping and leak-prevention work.
- Power Plants: Inspection of critical steam-line and nuclear piping alignment.
- Shipbuilding: Pipe and hull-plate alignment checks for marine fabrication work.
- Structural Steel: Weld-quality and alignment inspection for building and bridge fabrication.
