About us
A Burlington family business since 1960
Daniel Nielsen opened Dan's Welding & Fabricating in 1960. Three generations later his granddaughter Allison runs the shop alongside a crew of 28, ten of whom have been here more than twenty years.
That continuity is why plants across Southern Ontario keep coming back, the same people and the same standards, job after job.

Service details
Custom Machining at Dan's Welding & Fabricating
Dan's Welding & Fabricating provides precise, reliable, cost-effective custom machining for clients in Burlington, Hamilton, Oakville and across the GTA. We work from detailed drawings, CAD files or samples to produce machined components and fabricated assemblies that meet your dimensional and functional requirements, with clear communication and measurement verification at every stage.
Machining capabilities
We run conventional milling and lathe equipment built for accurate, repeatable results.
| Capability | Specification |
|---|---|
| Milling | 17 in Z axis x 32.9 in X axis x 14.5 in Y axis, tolerances to +/- .001 |
| Lathe | 11 in OD x 46 in length, tolerances to +/- .001 |
| Materials | Steel, stainless steel, aluminum, tool steels |
Why machining matters
Accurate machining makes sure metal components fit correctly within equipment, assemblies and structural systems. We produce parts to specified dimensions and tolerances so installation is clean and operation is consistent. Key benefits include:
- Dimensional accuracy for proper alignment
- Material suitability, matched to the application
- System compatibility with your existing equipment
- Flexible production, from single parts to small batches
Machining for preventive maintenance
Machining is not only for new builds. Preventive maintenance often means replacing worn components before they fail. We can recreate parts to original specifications, strengthen components with modified designs, and extend the working life of critical equipment, reducing unexpected downtime.
Quality control and workflow
Every job follows a structured workflow: we review drawings and confirm measurements, select suitable materials and tooling, machine the components to specification, then inspect each part for dimensional accuracy and finish before it leaves the shop.
Why Dan's Welding
- Milling & lathe capacity
- Tolerances to +/- .001
- Steel, stainless, aluminum, tool steel
- Replacement parts made to spec
- Machining plus fabrication in one shop
