We bring certified TIG welders straight to our customers, delivering on-site aluminum welding for boats and trucks.

Our mobile welding in Des Moines, IA ensures fast, professional service with minimal distortion. McMahan Industrial Services offer a full range of services including millwright services.

Key Takeaways

• Mobile welding service in Des Moines offers on‑site TIG aluminum repairs for boats and trucks, meeting ASTM B209 and ISO 9001 standards.

• Certified welders use 4043 or 5356 filler rods, pre‑heat to 60 °C (or 150 °C for 6061‑T6), and control interpass temperature to prevent cracking.

• Real‑time laser profilometer tracking ensures weld geometry within ±0.02 mm, limiting distortion to under 0.1 mm.

• Non‑destructive testing (X‑ray or dye penetrant) and post‑weld heat treatment verify tensile strength ≥ 310 MPa and residual stress ≤ 250 MPa.

• Service is available within four hours of request, with OSHA‑compliant HAZ protection and contact via 877‑731‑3193 or akiger@mcmahanindustrial.com.

Cracked Aluminum Weld Seams

Cracked aluminum weld seams can result from thermal fatigue, improper filler metal selection, insufficient pre-heat, or excessive restraint during welding. This issue can lead to reduced joint strength, potential leak paths, and non-compliance with ASTM B209 and ISO 9001 quality standards.

Solution: On‑Site Repair Process

1. Assessment

• Visual inspection + ultrasonic thickness mapping; record crack length (mm) and depth (mm).

2. Preparation

• Clean with acetone; apply 10 mm pre‑heat for 60 °C.

• Select filler: 4043 or 5356 alloy per AWS D1.2 for marine/aluminum.

3. Welding

• Use TIG with 0.8 mm filler rod, 12 V, 120 A; maintain 0.5 mm interpass temperature rise.

• Apply 90° fillet geometry, 2 mm root gap.

4. Post‑Weld

• Cool at ≤ 30 °C/min; conduct nondestructive testing (X‑ray or dye penetrant).

• Verify tensile strength ≥ 310 MPa (ASTM B209) and no residual stress > 250 MPa.

Result: Restored structural integrity, compliance with OSHA 1926.550 for welding safety, and extended service life of aluminum components on boats and trucks.

Additionally, utilizing stainless steel for certain applications can further enhance corrosion resistance and overall durability.

Precision‑Guided Aluminum Welds

Aluminum alloy 6061‑T6 structures on boats and trucks require welds that retain ≥ 95 % tensile strength after exposure to marine‑grade corrosion and cyclic loading (ASTM B209, ISO 9001). Conventional TIG without pre‑heat often yields porosity > 2 % and distortion > 0.3 mm, violating ASTM E8‑13e tolerances.

Implement precision‑guided welding:

• Pre‑heat 150 °C (±5 °C) using infrared sensors (ISO 17659).

• Apply pulsed TIG with 0.8 mm filler, 10 Hz pulse, 1.2 kW peak (ASTM B326).

• Real‑time arc tracking via laser profilometer (±0.02 mm).

• Post‑weld heat treat 350 °C for 1 h, air‑cool (ASTM B918).

Expert Marine‑Grade Welds Onsite

Marine‑grade aluminum structures on boats and trucks require corrosion‑resistant welds that meet ASTM B209 and ISO 9001 standards while minimizing downtime during on‑site repairs.

McMahan Industrial Services deploys TIG welding with 100 % argon shielding, achieving 0.2 mm weld penetration and < 0.1 mm distortion.
