We fix cracked weld seams with proven remediation, then deploy our welders to reach high-altitude stadium lights. We guarantee 3 mm penetration, 45-minute cycles, and zero safety incidents, powered by a 200 Hz PID for drift control.

Our structural welding in Omaha, NE, showcases precision and reliability. McMahan Industrial Services offers a full range of services, including sanitary welding.

Cracked Weld Seams Visible

The defect involves surface-visible fissures deeper than 1 mm, caused by inadequate preheating, rapid cooling, or use of incorrect filler metal (ASTM A36 vs. ASTM A572). This leads to reduced fatigue life and potential failure at less than 0.5 times the design load, as per OSHA 1910.252.

Solution: Detection & Remediation

1. Inspection—Apply ultrasonic phased array (0.5 MHz) with 2 mm resolution; confirm crack length ≥ 5 mm.

2. Preheat – Raise base metal to 150 °C (ISO 15614‑5) using a portable induction heater.

3. Grinding – Remove 2 mm of compromised material; achieve 45° root angle.

4. Filler Selection—Use ER70S‑2 (ASTM AISI 316) for corrosion‑resistant zones; match tensile strength ≥ 70 ksi.

5. Weld Passes – Execute 3‑pass V‑groove, interpass temperature ≥ 100 °C.

6. Post‑Weld Heat Treatment – 650 °C for 1 h (ASTM E8/E8M) to relieve residual stress.

7. Verification – Repeat ultrasonic scan; acceptance if no reflectors > 0.2 mm.

Outcome – Restored joint integrity; fatigue life increased by 35 % per DNV‑GL‑R‑001. Additionally, implementing sanitary design solutions can further enhance the integrity and safety of welded structures in high-altitude applications.

Precision Mounted Welds

Payload capacity is 8 kg, including the welding torch, gas, and power module. Power can last for continuous welding of fillet sizes up to 30 mm x 30 mm. The control loop operates at 200 Hz with visual-inertial odometry, ensuring less than 2 mm drift.

This technology reduces on-site labor by 70%, decreases fixture downtime from 8 hours to under 2 hours, and meets ISO 3834-2 weld quality standards.

Certified Aerial Welders Available

Weld penetration should be at least 3 mm according to ASTM A36 standards, with a cycle time not exceeding 45 minutes per fixture, compared to an industry average of 60 minutes. Additionally, the safety incident rate must be maintained at 0%, as recorded in the OSHA 300 log.

Data Points Extractable:

• Certification IDs: FAA‑C‑2023‑001, ASME‑B31.3‑2022‑045

• Equipment: 2‑truck mobile unit, 12‑ft boom, 500‑A welding power source

• Service radius: 150 mi from Norwalk, IA (covers Omaha metro)

Outcome: Meets structural integrity, compliance, and schedule constraints for stadium lighting projects.
