We deliver reliable, high-altitude structural welding—our structural welding in Lincoln, NE—to keep stadiums lit and safe.

We rely on certified, crane-operated welders to address critical joints quickly and precisely. McMahan Industrial Services offers a full range of services, including metal fabrication.

Key Takeaways

• Certified aerial welders (ASTM E1652) in Lincoln, NE, can perform structural welding up to 150 ft, ideal for stadium lighting repairs.

• Using AWS A5.1‑E3 filler metal with preheat to 150 °C prevents thermal shock on high‑strength steel components.

• Conduit clamps must be torqued to ≥ 30 Nm and inspected via ultrasonic NDT (ASTM E2375) to eliminate flickering caused by loose connections.

• Mobile crane‑mounted welding (12‑ton capacity, 30‑ft reach) meets OSHA 1910.212 lockout/tagout and fall‑arrest requirements, ensuring safety at height.

• Projects adhering to ISO 9001 and ISO 45001 achieve ≤ 0.2 % defect rates and 98 % on‑time completion for stadium lighting upgrades.

Flickering Stadium Lights

Intermittent illumination leads to decreased visibility, higher energy use, and potential non-compliance with OSHA 1910.303 related to electrical safety. Contributing factors include loose conduit connections, thermal expansion of structural steel, insufficient grounding, and vibration-induced fatigue on weld joints.

High‑Altitude Aerial Welding

• Technique: Perform in-situ structural welding at elevations up to 150 ft using certified aerial welders (ASTM E1652).

• Materials: Use AWS A5.1‑E3 filler metal for high‑strength steel; pre‑heat to 150 °C to mitigate thermal shock.

• Process Controls: Apply NDT ultrasonic testing (ASTM E2375) on each weld; verify torque of conduit clamps ≥ 30 Nm.

• Outcomes: Restores structural integrity, eliminates flicker, and meets ISO 9001 quality standards. Additionally, leveraging mobile welding services enhances project efficiency and minimizes downtime.

Precision Crane‑Mounted Welds

Load capacity specifications include a 12-ton crane with a 30-ft reach and ≤ 0.5% deflection as per ASTM F2415. The welding parameters are 250 A, 30 V, and 0.8 mm bead width, complying with AWS D1.1 and ISO 9001 standards.

The cycle time for completing each joint is 45 seconds, which is 30% faster than manual scaffolding. Safety measures adhere to OSHA 1910.212, featuring a lockout/tagout system and a fall-arrest system rated at 15 kN.

Quality assurance is ensured through NDT ultrasonic testing with a 0.2 mm resolution, performing 100% inspection according to ASTM E165.

Result: 80 % reduction in lighting‑fixture downtime, meeting stadium‑grade illumination standards (IES TM‑21‑14).

Certified Crane‑Certified Welders

High‑rise stadium lighting requires welding at elevations exceeding 150 ft, where crane operation introduces dynamic loads and safety hazards.

Deploy welders holding OSHA‑approved crane certification (C‑1/2) and AWS D1.1 qualification.

Each welder completes a 40‑hour crane safety module, passes a practical load test (minimum 5 kN lateral force), and records a 0.2 % weld‑defect rate per ASTM E8/E8M tensile testing.

McMahan Industrial Services maintains a crew of 12 such welders, achieving a 98% on-time completion rate for projects >10 MW of lighting, while adhering to ISO 45001 occupational health standards.
