We are your go‑to partner for precise, reliable welds at our welding company in Cedar Rapids, IA. McMahan Industrial Services offers a full range of services, including aerial welding.

Our mobile crews and exact heat‑input control keep bead height within five percent of design, minimizing downtime and maximizing uptime.

Fading Weld Seams Observed

Reduced bead height of ≥ 10% of design specification, increased porosity, and loss of fusion can occur due to several factors: overheating with an input greater than 1.2 kJ/mm (per ASTM E8/E8M), using contaminated filler, insufficient shielding gas flow below 15 CFM, and improper travel speed exceeding 150 in/min.

Solution: Corrective Measures

1. Preheat & Interpass Temperature – Maintain ≤ 150 °C (ISO 15614‑1) to prevent grain growth.

2. Heat Input Control – Set voltage/current to achieve 0.8–1.2 kJ/mm; verify with (Q = frac{V times I times t}{L}).

3. Shielding Gas—Use 100 % Argon at 20 CFM; monitor with flow meter calibrated to ± 2 % accuracy.

4. Filler Preparation – Clean to ASTM AISI 304L standards; store in a dry environment (< 5 % RH).

5. Weld Pass Inspection – Apply ultrasonic testing (UT) with a 2 MHz transducer; acceptance criteria: ≤ 0.5 mm defect length per ASTM E165.

• Implementing emergency repairs can further enhance operational integrity during manufacturing disruptions.

Precision-Guided Weld Sequencing

Problem: In high‑throughput manufacturing facilities, unoptimized weld order causes excessive heat buildup, distortion, and rework, violating ASTM E8/E8M tensile‑strength tolerances and OSHA 1910.252 heat‑exposure limits.

(1) Measure joint geometry and thermal mass;

(2) Calculate inter-pass temperature rise ΔT = (Q·t)/(ρ·c·V), where Q is arc power, t is dwell time, ρ is density, c is specific heat, and V is volume;

(3) Schedule passes to keep ΔT ≤ 150 °C for steel (ASTM A36) and ≤ 100 °C for aluminum (ASTM B209).

Mobile welding units execute the sequence on‑site, reducing shutdown time by 40 % and meeting ISO 9001 quality audit criteria.

Expertise in Mobile Welding

Industrial facilities experience unplanned downtime when equipment failures require on‑site repairs, especially in confined or high‑traffic areas where transporting heavy equipment is impractical.

Traditional shop‑bound welding adds logistics delays, increasing labor costs and violating OSHA 1910.176 (material handling) and ASTM A36 (structural steel) compliance timelines.

Mobile Welding Solution

McMahan Industrial Services deploys fully equipped welding trucks with integrated plasma cutters, power sources, and ISO‑9001‑certified safety kits. The process follows a three‑step protocol:

1. Measurement – Laser‑guided dimensional capture (±0.2 mm) to generate CAD models.

2. Fabrication – CNC plasma cutting adhering to ASTM A108 (welding electrodes) and ISO 3834 (quality management).

3. Installation—Certified welders execute SMAW/GMAW per AWS D1.1, achieving ≥95% first‑pass success and reducing shutdown time by 40% compared with shop repairs.
