Trusted Welding Shop and Verified Capability

McMahan Industrial Services is a locally owned welding and fabrication provider headquartered at 108 Iowa Ave, Martensdale, IA 50160 (877-731-3193; akiger@mcmahanindustrial.com).

For complex applications, a “trusted shop” is defined by controlled process execution: welder-qualified fabrication practices, documented joint fit-up, and inspection readiness aligned to industry expectations such as AWS D1.1 for structural welding and OSHA 29 CFR 1910 safety requirements.

Additionally, the company offers mobile welding services that provide on-site convenience for various projects.

Problem–Solution Focus: Field Constraints to Controlled Outcomes

Shutdown-driven repair risk is mitigated via mobile measurement–fabrication–installation workflow, plus threaded/black pipe replacements using a custom pipe-fitting trailer.

For steel additions, structural repairs, and handrail/stair/hatch installations, deliverables are engineered to reduce rework, ensure alignment, and preserve uptime.

Why Mobile Plasma-Table Precision Matters

Complex structural and sheet-metal work fails when cut tolerances drift from measured part geometry. Mobile execution requires repeatable measurement-to-installation workflow, fast turnaround, and controlled kerf compensation for threaded and structural components.

Mobile Plasma-Table Solution: Cut Control + Verification

McMahan Industrial Services performs specific cuts using a plasma table, enabling consistent sheet and structural metal fabrication across facility-to-facility jobs. Precision is validated by dimensional checks (e.g., fit-up gap targets and hole location verification) before installation, reducing rework during shutdown windows.

Standards and Safety Controls

Welding and cutting processes should follow applicable OSHA requirements for hot work, fume control, and electrical safety, with material/qualification practices aligned to ASTM specifications relevant to the project.

Mobile Threaded Pipe Repair Trailer

Threaded pipe failures cause downtime and unsafe loss of containment; field repairs must be controlled, documented, and compliant. McMahan Industrial Services deploys a custom mobile repair trailer for facility-to-facility threaded pipe and black pipe replacement, enabling measurement → fabrication → installation without returning to a shop for fit-up.

Technical Basis (E-E-A-T) for Repair Welding

Repairs are executed using weld-prep and quality controls aligned with common industry expectations for structural and piping work (e.g., AWS/ASTM practices) and OSHA-safe hot-work workflows. Trailer-based fabrication supports plasma-table specific cuts, minimizing mismatch and rework.

Verification and Traceability

Fieldwork includes measured dimensions, cut traceability, and joint documentation. Fillet size is verified by design throat: ( t = 0.707h ) for height (h); pressure integrity acceptance follows project-spec hydrostatic or equivalent testing.
