ISO 9001 certification demonstrates organizational commitment to quality management across all fabrication activities. Many customers require third-party certification as a prerequisite for supplier qualification.
Field Services and On-Site Capabilities
While shop-based all fabrication offers controlled environments and full equipment access, many projects require on-site services that bring capabilities directly to operating facilities.
Mobile Welding Applications
Field welding addresses repair needs and installation requirements that cannot be accommodated in fabrication shops:
Emergency repairs minimize downtime by dispatching qualified welders with portable equipment to failed components. Conveyor systems, structural supports, and process equipment often require immediate attention to restore production.
New installations integrate fabricated components into existing infrastructure. Large assemblies may be pre-fabricated in sections, then welded together on-site to eliminate transportation limitations.
Modification projects adapt facilities to changing operational requirements. Custom welding solutions enable quick turnaround on upgrades without extended shutdowns.
Portable Machining Equipment
Line boring, flange facing, and in-situ machining restore dimensional accuracy without removing equipment from service locations:
- Bearing journals machined to precise diameters and surface finishes
- Mounting flanges faced flat within 0.002 inches
- Bolt holes re-drilled to correct alignment issues
- Gear teeth repaired through specialized machining techniques
Access limitations often determine whether portable machining represents the most practical solution. Equipment that would require weeks to disassemble and transport might be machined in place within days.
Hydraulic Systems Integration
All fabrication frequently incorporates hydraulic components that enable motion control, force application, and power transmission across industrial equipment.
Hydraulic Fabrication Requirements
Hydraulic systems demand exceptional cleanliness and precision during all fabrication operations:
