Struggling With Delayed Repairs or Hard-to-Reach Welding Projects?

Mobile welding offers a flexible solution when traditional shop work just won’t cut it. At Alfonso's Welding, we bring professional-grade welding directly to your location to keep your projects on track and minimize downtime. Based in Napa, CA, our team understands the unique challenges that come with remote repairs and site-specific needs. Many clients face long wait times or transport issues when trying to fix equipment offsite. Others worry about inconsistent service quality from unfamiliar providers. With over 25 years of industry experience and a presence in the community since 2016, we’ve built our reputation by delivering consistent results through licensed, onsite support. Our approach blends technical skill with responsiveness, helping you avoid unnecessary delays and get back to work quickly. Whether you’re repairing structural steel or fine-tuning aluminum parts, we provide mobile solutions tailored to your job site conditions and timeline expectations.

We Specialize in the Following Services

Metal Welding

Metal Welding

Structural components made of metal often suffer wear, corrosion, or impact damage, posing risks to safety and function. Metal welding provides a versatile repair method for these situations, allowing us to restore strength and continuity without removing the part from its environment. By mobilizing advanced tools and proven techniques, our team addresses everything from minor stress cracks to full joint separations right where the problem exists. The result is a fast-turnaround solution that keeps your equipment operating safely while avoiding disassembly or costly replacements.
Pipe Welding

Pipe Welding

Leaking or damaged piping can disrupt operations, lead to environmental hazards, or inflate utility costs if left unresolved. Pipe welding delivers precise remediation by sealing fractures and reinforcing joints under demanding conditions. We handle both pressure-rated and non-pressurized systems across various diameters and materials. Our crew adapts to indoor or outdoor settings, whether you're dealing with process lines or structural piping. This focused service ensures restored integrity with minimal interruption, helping you maintain compliance and prevent further complications down the line.
Aluminum Welding

Aluminum Welding

Aluminum requires special handling due to its lower melting point and unique oxide layer that resists bonding. Aluminum welding solves this challenge by using appropriate filler metals, shielding gases, and temperature controls specific to non-ferrous applications. Our mobile setup allows us to perform highly controlled welds on trailers, machinery frames, housings, or architectural features wherever they are located. Customers benefit from reliable aluminum restoration that preserves appearance and performance without needing transportation to a specialty shop.
Steel Welding

Steel Welding

Damaged steel beams, supports, or frames can jeopardize load-bearing capacity in both commercial and industrial environments. Steel welding reinforces these structures by adding new material or rejoining fractured sections using high-strength techniques tailored for carbon-based alloys. We evaluate each situation onsite to determine heat input requirements and necessary pre-cleaning procedures. Mobile access means faster response times and less disruption to surrounding activity. In most cases, clients regain structural confidence immediately after completion—without waiting for extended fabrication timelines.
