Every service runs under a 4-hour industrial minimum of $600, which covers a full crew and a properly equipped rig on every dispatch. 1. Heavy Equipment Welding 2. Stainless Steel Pipe Welding 3. Maritime and Municipal Structural Welding 4. Welding Repair 5. Structural Steel Fabrication 6. Custom Metal Fabrication Materials across all six: carbon steel, structural steel, stainless steel, and aluminum. --- ### Heavy Equipment Welding **What it is:** Bucket repair, hard-facing, pin and sleeve machining, line boring, crack and structural repair, and wear plate welding on construction and rental fleet machinery, performed at the jobsite. Heavy equipment rarely travels well, so two fully equipped rigs bring the welding and machining capability to the machine instead. Service page: https://hrtmobilewelding.com/heavy-equipment-welding/ **Best for:** Rental yards, construction fleets, and facility operators with an excavator, wheel loader, bulldozer, skid steer, trailer, or dump body that is down or wearing out, where trailering it to a shop would cost more in downtime than the repair. **Our process:** 1. You tell us the machine, the failure, and where it sits; a photo lets us arrive with the right process, filler, and machining setup. 2. We dispatch a rig to the machine with the power, gas, consumables, and machining capability the job needs. 3. Worn bores are line bored back to true on the machine, then pins and sleeves are fitted to return the joint to original clearance. 4. Cutting edges, side plates, and wear surfaces are rebuilt, then hard-faced with a wear-resistant alloy. 5. Cracks in booms, sticks, frames, and load-bearing members are prepped, welded, and reinforced so the crack does not reappear beside the bead. 6. Smaller attachments and components that travel easily go to the shop bench when that gives a better result. **What's included:** - Bucket repair and hard-facing of cutting edges, side plates, and wear surfaces - Pin and sleeve machining to restore worn pin bores to original clearance - Line boring in place, without teardown - Crack and structural repair on booms, sticks, frames, and load-bearing members - Wear plate and liner replacement on beds, chutes, blades, and buckets - Attachment brackets, quick couplers, guarding, and mounting points - Replacement parts fabricated from the failed original or from measurements when a part is beyond repair **Outcomes:** The machine returns to service where it sits, with substantially longer service life between rebuilds. Straightening and rewelding bent components on site for construction and excavation companies is an example of this work. --- ### Stainless Steel Pipe Welding **What it is:** Stainless steel pipe welding for large-scale plumbing, mechanical systems, process piping, and data center cooling loops, welded to a zero-defect standard on site by American Welding Society certified welders. Service page: https://hrtmobilewelding.com/pipe-welding/ **Best for:** Data center and infrastructure contractors, mechanical contractors, large-scale plumbing contractors whose job has outgrown standard trade work, and facility engineers needing in-service pipe repair without a full shutdown. **Our process:** 1. Send the diameter, material, spec, and site conditions; we confirm all four before quoting. 2. Spool work that can be prefabricated is welded on the bench in Livermore, where tolerances are easiest to hold. 3. Two fully equipped rigs carry the power, gas, and consumables to weld pipe on site where the run has to go. 4. Welds are made to a zero-defect standard for systems that get pressure tested before service. 5. Pipe supports, hangers, and mounting brackets are fabricated to fit the actual run rather than a catalog part. **What's included:** - Stainless steel pipe welding, plus carbon steel and aluminum - Mechanical system installation and process piping for industrial and commercial facilities - Cooling loop and chilled water piping for pressurized data center systems - Support for large-scale plumbing contractors on oversized or specialty-spec jobs - Pipe repair and in-service modification of existing runs - Hangers, supports, and brackets fabricated to the run **Outcomes:** Welds that pass pressure test and stay in service. Stainless pipe was welded for a mechanical contractor's cooling system at a Bay Area data center. --- ### Maritime and Municipal Structural Welding **What it is:** Structural repair, reinforcement, and modification inside operating port facilities, on municipal and government projects, and for signal arm manufacturers, completed under strict maritime safety protocols in environments that cannot shut down. Service page: https://hrtmobilewelding.com/maritime-structural-welding/ **Best for:** Port facilities, municipal and government agencies that require a licensed California contractor, signal arm manufacturers, and infrastructure contractors working in access-constrained or safety-governed environments. **Our process:** 1. Send the scope with the site's safety and access requirements; on port and municipal work those decide the schedule, not the welding. 2. We sequence the work around operations so nothing has to pause. 3. Structural repair, reinforcement, and modification are performed in place by AWS certified welding specialists. 4. Replacement components are fabricated in the Livermore shop and installed on site by the same crew. 5. Insurance certificates and license documentation are provided before mobilization. **What's included:** - Port facility structural repair and reinforcement - On-site structural modification of standing structure - Structural welding and fabrication support for signal arm manufacturers - Structural welding for municipal and government projects - Emergency structural repair in operating environments - Fabrication of replacement components **Outcomes:** Structural work completed with zero disruption to operations. Structural repairs and modifications at the Port of Oakland, one of the West Coast's busiest port facilities, were completed on site under strict maritime safety protocols with full compliance and zero operational downtime for the port. --- ### Welding Repair **What it is:** On-site repair of cracked frames, split seams, leaking tanks and housings, load-bearing steel, trailer frames and hitches, gates, railings, and fences, dispatched to the site by two fully equipped mobile rigs. Emergency calls are welcome. Service page: https://hrtmobilewelding.com/welding-repair/ **Best for:** Fleet and equipment operators with a machine down, general contractors who found a crack mid-build, facility and plant managers with failed structure, racking, guarding, or process equipment, and property owners with a broken gate, railing, or fence that is now a safety or security problem. **Our process:** 1. Call (925) 518-6694 or send the form; describe what failed and send a photo so we arrive with the right process, filler, and gas. 2. We tell you our honest availability and a realistic cost range before dispatch. 3. A rig comes to the site for anything that cannot easily be moved; parts that can travel go to the shop bench for better access and positioning. 4. The damage is prepped properly and welded so the crack does not simply walk past the repair. 5. If the component is past saving, we fabricate the replacement from the failed original or from measurements. **What's included:** - Crack and leak repair on frames, seams, tanks, and housings - Structural welding repair and reinforcement of load-bearing steel in place - Heavy equipment repair on buckets, booms, blades, and frames - Trailer frame, hitch, landing gear, gate, and deck repair - Gate, fence, railing, and post repair in place - Replacement fabrication when repair is not the right answer - Carbon steel, structural steel, stainless steel, and aluminum **Outcomes:** The broken item is back in service without being transported, or replaced with a part built to the real dimensions. Customers have described a bent trailer jack and mount repaired rather than replaced, and a baler floor rebuild that got the machine running again quickly. --- ### Structural Steel Fabrication **What it is:** Beams, columns, base plates, frames, welded assemblies, heavy plate, and structural-grade gates and railings fabricated to your drawings in our Livermore shop and installed on site by a C-60 licensed California contractor, plus reinforcement, member replacement, and modification welded on structures already standing. Service page: https://hrtmobilewelding.com/steel-fabrication/ **Best for:** General contractors sourcing a licensed fabricator for structural packages, project managers and engineers who need steel fabricated to drawing and certified installed, facility engineering needing structural modification in an operating building, and infrastructure or maritime clients working under access and safety constraints. **Our process:** 1. Send the drawing set, material spec, and site conditions; we confirm what we can hold and flag any detail that will cause a problem in the field before fabrication starts. 2. Layout, cutting, forming, and fit-up happen in the Livermore shop, where fit is easiest to verify before anything ships. 3. The special inspection agency and submittal path are confirmed with the building department before fabrication, since Chapter 17 of the California Building Code requires special inspection of structural steel welding for shop and field work alike. 4. Two fully equipped rigs handle connection welding, in-place modification, and reinforcement on site. 5. Material is supplied by us or by you; tell us which when you request the quote, because it changes the number and the lead time. **What's included:** - Steel frame and assembly fabrication: beams, columns, base plates, welded assemblies - Custom structural-grade gates, guardrail, handrail, and stair rail - Heavy plate cutting, forming, and welding for bases, wear surfaces, and load-bearing plate - Structural repair and modification on standing structure - Equipment structural work on booms, frames, and load-bearing members - Carbon and structural steel, stainless steel, and aluminum **Outcomes:** Steel fabricated to drawing and certified installed by one contractor under one license, with no gap between fabricator and installer. --- ### Custom Metal Fabrication **What it is:** Custom gates and fencing, equipment guards and brackets, skid frames, heavy plate, and one-off parts built to a drawing, a measurement, or a failed original we reverse engineer, in a working fabrication shop with two mobile rigs for field fit-up and installation. Service page: https://hrtmobilewelding.com/metal-fabrication/ **Best for:** General contractors needing structural components fabricated and installed, equipment operators and rental fleets needing custom guards, brackets, and attachment points, facility managers with one-off fabrication and machine guarding work, and property owners needing gates, railings, and security fencing built to a real opening. **Our process:** 1. Bring a drawing, a sketch, a measurement, or the failed part; we tell you what it takes. 2. For fabrication we usually want dimensions, material, and quantity, plus a photo if you have one. 3. Layout, cutting, forming, fit-up, and finish work happen on the bench in Livermore, where tolerances are easiest to hold and the weather never matters. 4. When the work cannot move, the rigs handle field fit-up, in-place modification, and welding on structures already standing. 5. If the part can be saved instead, we say so and route it to welding repair as the cheaper path. **What's included:** - Custom steel gates, security gates, railings, and fencing built to the actual opening - Equipment guards, mounting brackets, skid frames, and custom attachment points - Heavy plate cutting, forming, and welding for wear surfaces, bases, and load-bearing components - Custom parts and components, including obsolete and discontinued replacements - Structural steel fabrication to drawings (code-driven structural packages run through our structural steel fabrication service) - Carbon steel, structural steel, stainless steel, and aluminum **Outcomes:** A part built to the opening or mount you actually have, fabricated and installed by one contractor with one point of accountability. --- ## About HRT Mobile Welding HRT Mobile Welding is a C-60 licensed mobile welding and metal fabrication contractor based at 3555c First St, Livermore, CA 94551.
