Duct Connection Welding Rack

Features of Duct Connection Welding Rack

• Precision Alignment System: Secures Ø80-1500mm ducts with ±0.3mm radial tolerance (AWS D3.7 compliant) and ±0.5° angular accuracy via adjustable clamping arms.

• Ovality Control Technology: Patented HYRUN contour rollers maintain circularity during welding, eliminating SMACNA non-compliant joints.

• Rapid Tool-Free Setup: Reduces fit-up time by 50% with self-centering mechanism, verified per EN 1090-2 Class B standards.

• TIG/MIG Process Optimization: All-position compatible design ensures full argon shielding for 0.5-1.2mm GI/SGCC/aluminum duct girth welds.

• Industrial Safety & Durability: Hard-anodized frame ISO 9001 dual-hand controls and spatter-resistant clamps for 24/7 shop-floor operation.

Steps to Use and Points to Note of Duct Connection Welding Rack

• Fixture Setup: Mount rack on level floor; verify laser alignment emitter calibration per HYRUN manual (EN ISO 9013:2017).

• Duct Positioning: Secure Ø80-1500mm ducts with contour rollers, ensuring ≤0.3mm gap and ±0.5° angular alignment (AWS D3.7).

• Welding Execution: Initiate TIG/MIG welding; maintain argon shielding. Never bypass fume extraction or touch live clamps.

• Real-Time Monitoring: Check ovality (≤1mm/m per SMACNA) using integrated laser micrometer during welding.

• Post-Weld Maintenance: Clean rollers after use; inspect clamp jaws monthly for wear (HYRUN Part No. RCJ-2024).
