Steel Fabricator


JW is a Steel Fabricator with mechanical expertise for quick turnover of Steel Fabrication in maintenance projects in London, Ontario. In fact, we are an expert in mechanical maintenance where steel fabrication plays a major role. Therefore, we differ significantly from other steel fabricators that specialize in structural steel fabrication.

More importantly, due to our mechanical specialization the mild steel fabrication relates rather to fabricating specific one piece or multiple pieces that performs designated functions. And, the fabricated element or its portion must be able to exercise certain movements. And it has to be able to resist certain vibrations. With this in mind, we are ready to build prototypes for clients willing to test their ideas.

If you are looking for a steel fabricator for your precision steel fabrication project, you are welcome to initiate our quoting process by attaching the drawings of your planned steel fabrication to your email. Although, we gladly respond to all quoting inquiries, we are most capable in area of precision steel fabrication.  In case, you are looking for precision steel fabrication and you do not have engineering drawings but you know exactly what you want than please attach you sketch of your idea to your email. And we will accomplish the rest.

Presently, we do not accept projects in area of structural steel fabrication unless they should be completed on client’s construction site.

Steel fabrication & re-fabrication using GTAW (Tig) and GMAW (Mig) welding mild steel

In general, we usually over weld our steel fabrication projects. It is important to realize that, the nature of steel fabrication in maintenance projects directly influence our fabrication’s over – welding pattern. On the positive side, as much as we would like to change this pattern and reduce our labor and welding consumables cost, so far, we have failed  in this attempt.

In reality, our steel fabrication projects do not start with drawings or sketches but it starts with the mild steel element that used to be part of the machine. Another key point is that we are steel fabricator that fabricates the new steel fabrication based on the old steel fabrication. And this is a major difference between us and other steel fabricators.

The steel fabrication starts in our shop with the piece on the welder’s table that has metal cracks and weld cracks in multiple places. Most often, its bushing seats are completely warn out and the whole piece is usually bent. So, in reality, we get a scrap metal that initiates the project.

In particular, the project lands on our fabrication table because

  1. equipment manufacturer does not manufacture this replacement element any more,
  2. new elements manufactured by the equipment manufacturer can not sustain mechanical abuse and end up as scrap relatively quickly,
  3. element is rusted and lost its structural integrity,
  4. old element must be modified since its functionality has changed (ex – has to accommodate new attachment.

More we know about your steel fabrication project that is part of your machine than is better

When you are faced with any of scenarios described above please do not remove this damaged element from your machine. Since we would like to see this damaged element prior its removal and we would like to talk to the machinery or equipment operator. To clarify, we value your operator’s comments tremendously. These comments, as our experience tells us, will have a significant impact on your project too.

Cutting the scrap to know more about your steel fabrication project

Our steel fabrication projects are not over-engineered simply because our clients do not have funds to over-engineer their project either. Generally speaking, our clients want simple solutions to rather complicated problems. Therefore, we cut the scrapped element to understand what kind of damages it sustained. It could surprise you how much we learn about scrapped element by skillfully cutting it in few places. It would also surprise you how valuable is this technique for the success of your steel fabrication project.

Once, we know why we are dealing with such damages than we make decision to remedy the problems. In remedy to the problem we consider following:

  1. thicker elements,
  2. bigger and stronger welds made from high tensile consumables,
  3. strange looking gusset plates that protect and strengthen the main element,
  4. bearing seats made from hardened material,
  5. better quality mechanical parts,
    • superior bearings,
    • better gears and pulleys,
  6. convenient for operator lubrication system that actually works,
  7. anti – vibration pads and surfaces,
  8. epoxy rust inhibitor inside the elements,
  9. friction and/or impact resistance surface welded with surfacing welding consumables and so on.

Your steel fabrication project involves more than one visitation on site in order to make sure that we are going in the right direction. And, then the installation visit that always involves final welding on site with our main mobile welding unit.

Machine guarding fabrication and custom safety guards

It is worth mentioning that we fabricate custom safety guards for machinery and heavy equipment. Variety of equipment and machinery requires new safety guards or requires modified machine guarding. Indeed, our fabricated guards meet owner, operator and/or maintenance crew requests. And fulfill safety requirements of your safety representative.

Most often, the new machinery and new heavy equipment lands in Ontario and usually is already equipped with some kind of machine guarding. But, in many instances, these safety guards do not meet the requirements of the new owner or operator due to following reasons:

  1. insufficient protection of sensitive components against the operator’s abuse,
  2. lack of inspection windows for systematic visual inspection,
  3. difficult access to grease lines’s fittings,
  4. operator access to moving parts,

We understand that we must bring flexible designs to fulfill requirements of owner, operator and safety rep.

In most instances, we built the model of a new safety guard prior fabrication. Then we fabricate the new safety guard in the shop. And then we install the new safety guard to your equipment or machinery. During the guard’s final installation, we do final modification that involves some on site welding.

Steel Fabricator for overhaul and maintenance

Again, we are perfect steel fabricator for overhaul and maintenance projects since we can accomplish steel fabrication projects quickly with minimum supervision. Our industrial millwright experience guide us in the process. As millwrights, we can install them too. So, at the end of the day we minimize headaches for young engineers running maintenance departments.

The ability to fabricate structures based on maintenance manager’s sketches and then install them in place makes us a fabricator to go in London area for:

  1. repair and maintenance,
  2. preventative maintenance, and
  3. machinery overhaul.

Majority of steel fabrication takes place in the shop however; our mobile unit is useful for installation and minor modification of the fabricated structures. The extensive millwrighting background helps us  to predict the fabricated structure behavior even though the details are not mentioned on the maintenance manager’s sketch.
