Welding Guage HJC-30
. It is a specialized, multi-purpose stainless steel tool used by weld inspectors and fabricators to verify structural dimensions and joint quality against technical specifications.
 
. Key Inspection Functions
   - Weld Seam Width & Reinforcement : Measures the overall face width of the weld bead (0 to 30 mm) and the reinforcement height or crown profile (0 to 12 mm) using the integrated center pointer slide.
   - Bevel & Groove Angles : Features multiple fixed angular templates (45°, 55°, 60°, 65°) and a movable bevel arm to quickly verify preparation angles from 20° up to 80°.
   - Fit-Up Gap Width : The graduated stepped gauge on the secondary piece (shown on the bottom right) checks fit-up clearance gap widths between joint components ranging from 0.5 mm to 3.5 mm.
   - Fillet Weld Size: Assists in checking fillet weld throat thickness and leg length tolerances.
