The Paprsky Hi-Lo Single Purpose Welding Gauge (Retract) is a stainless-steel inspection tool designed for pre-weld fit-up checks. It is used to measure internal misalignment and root gap between components before welding, helping users confirm proper alignment and joint dimensions. With metric scales and a retractable design, the gauge provides a practical method for checking weld-joint preparation in fabrication and field environments. Accurate alignment and root-gap verification can help support weld strength, penetration, and overall weld integrity.
Paprsky provides practical welding inspection tools designed to support reliable dimensional checking in fabrication and field environments. The Hi-Lo Single Purpose Welding Gauge (Retract) offers a straightforward solution for measuring root gap and internal misalignment before welding, helping users evaluate joint fit-up and preparation.

Key Features
- Internal Misalignment Measurement: Helps check alignment differences between joint components before welding.
- Root-Gap Measurement: Supports verification of the gap between components during fit-up.
- Metric Scale: Provides measurements in millimetres for convenient inspection.
- Locking Screw: Allows the gauge position to be secured once the measurement is taken.
- Stainless-Steel Construction: Suitable for regular use in welding, fabrication, and quality-control environments.
Usage Instructions
- Loosen the locking screw to enable gauge movement.
- Position the fixed legs within the root gap of the components.
- Observe the root-gap and internal-misalignment readings on the metric scales.
- Tighten the locking screw to secure the measurement position.
- Remove the gauge and note the readings shown on the scales.
- Compare the measured values with the applicable weld-fit-up requirement or specification.
Applications
- Pipeline Welding: Checking alignment and root-gap dimensions for oil and gas pipeline joints.
- Structural Fabrication: Verifying the fit-up of beams, plates, and other structural components before assembly.
- Pressure Vessel Manufacturing: Checking alignment and gaps in shells and heads before welding.
- Boiler and Heat Exchanger Assembly: Verifying alignment and root gaps for tube-to-tube-sheet joints.
- Welding Inspection: Supporting pre-weld inspection and dimensional quality-control checks.
