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.

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.
