Precision Welding
MIG and TIG welding support structural welds, cosmetic welds, sealed welds, enclosures, weldments, chassis systems, and fabricated assemblies built to customer drawings.
From precision MIG and TIG welding to full-service metal fabrication, Ron Nunes Enterprises helps manufacturers turn drawings into durable, production-ready components. With over 55 years of experience, in-house fabrication capabilities, and support from prototype through production, our team delivers cost-effective solutions for demanding commercial, industrial, transportation, defense, and technology applications.

Complete welding and fabrication support for precision parts, chassis systems, assemblies, prototypes, and production runs.
MIG and TIG welding support structural welds, cosmetic welds, sealed welds, enclosures, weldments, chassis systems, and fabricated assemblies built to customer drawings.
Custom sheet and plate components are fabricated from prototypes to production runs, helping customers move from early concepts to repeatable manufactured parts.
Precision laser cutting produces intricate profiles, tight tolerances, and clean edges across steel, stainless steel, and aluminum sheet or plate materials.
Press brake forming creates angles, channels, boxes, enclosures, chassis parts, and complex sheet metal geometries for durable fabricated components.
Mechanical assembly combines fabricated parts into finished units with hardware insertion, riveting, multi-part weldments, chassis systems, and production-ready assemblies.
Finishing support prepares parts for shipment through deburring, graining, and coordination of coated or plated finishes when needed for the application.

Established in 1969 by Ron Nunes, Ron Nunes Enterprises was founded to meet the growing need for manufacturing services across a broad range of applications. From its Livermore, California headquarters, the company has evolved into a full-service precision metal fabrication manufacturer serving commercial, industrial, public, and private sector customers. Over more than 55 years, the team has expanded capabilities across laser cutting, shearing, N/C punching, forming, welding, assembly, and finishing. Today, Ron Nunes Enterprises supports communications, telecommunications, transportation, nuclear and physics research, national defense, medical, and semiconductor customers with cost-effective manufacturing applications, product development support, scheduling integration, and a continued commitment to manufacturing excellence.
Metal fabricator pricing is usually based on shop time, material type, material thickness, weld requirements, tolerances, setup, finishing, and order quantity. Ron Nunes Enterprises does not publish standard hourly rates because custom metal work is quoted from drawings and specifications. A detailed quote typically provides a clearer cost picture than an hourly estimate alone.
