• They provide professional welding (AWS E7018 filler) and post‑weld heat treatment to prevent cracked weld seams, complying with OSHA 1926.750.

• Production includes CNC plasma tables (0.02 mm positioning) delivering brackets within 48 hours from CAD approval.

• Services are locally based in Lincoln, NE, supporting on‑site installation with lockout/tagout safety per OSHA 1910.212.

• Client reviews confirm high quality, reduced rework (<2% variance and cost savings), and reliable certification‑ready components.

Cracked Weld Seams Appear

Visual indicators of welding issues include irregular or jagged edges, referred to as "crazing," along the weld bead. The root causes for this phenomenon can be excessive heat input (greater than 0.8 kJ/mm), rapid cooling, contamination (such as oil or rust), or the use of improper filler materials (like ASTM A241 instead of A36).

Solution – Remediation Protocol

1. Inspection – Perform ultrasonic testing (UT) per ASTM E165; record defect length and depth.

2. Preheat – Raise base metal temperature to 150 °C (ISO 15614‑1) for carbon steel > 0.25 % C.

3. Re‑weld – Use appropriate filler (AWS E7018) with controlled heat input (0.5–0.7 kJ/mm).

4. Post‑weld heat treatment – Apply PWHT at 620 °C for 1 h per ASME Section VIII.

5. Verification – Conduct visual inspection (VI) and magnetic particle testing (MPT) to confirm seam integrity.

Metrics– Acceptable crack length < 2 mm; depth < 10 % wall thickness; weld reinforcement ≤ 1.5 mm. Additionally, ensuring compliance with AWS D1.1 structural certificationcan enhance the overall quality of the welds.
Compliance– Aligns with OSHA 1926.750 and ISO 3834‑2 quality standards.

Laser‑Cut Precision Brackets

Industrial facilities require brackets with tight tolerances to support equipment, ensure safety, and meet ASTM F1554‑98 and ISO 9001 quality standards. Conventional manual welding introduces dimensional variance (±0.5 mm) and rework costs up to 12% of project budget.

Laser‑cut precision brackets fabricated from ASTM A36 or AISI 304 stainless steel achieve ±0.05 mm tolerance, reducing rework to <2% and complying with OSHA 1910.22 for load‑bearing components.

McMahan Industrial Services employs CNC plasma tables with 0.02 mm positioning accuracy, delivering 100% repeatability for custom bracket geometries up to 150 mm thickness. 

Plasma‑Cut Precision Brackets

• Tolerance: ±0.005 in (±0.127 mm) on all dimensions, verified by calibrated CMM.

• Edge quality: less than 0.2 mm dross and meets ASTM A905 surface finish.

• Material: 0.5 in (12.7 mm) carbon steel, ASTM A36, heat-treated to 0.55% carbon.

• Production rate: 150 brackets / hour per 3-kW plasma table, 99.2% first-pass yield.

• Compliance: OSHA 1910.212 lockout/tagout procedures were applied during installation.

• Lead time: 48 h from CAD submission to field delivery, including on-site welding and alignment verification.

Result: Eliminates assembly variance, reduces rework cost by 35%, and ensures certification-ready components for large-scale industrial projects.
