Welding company in London Ontario – projects on construction site

The beginning of JW Portable Welding & Repairs, welding company in London Ontario, commercial operation, originated in providing auxiliary welding services in construction of apartment buildings, industrial buildings and other high-rise constructions. While working for builders, we have realized that we need to focus on the top floor operation. Specifically, this is where the action is. Unfortunately, most mobile welders reach maximum of first 3 or 4 floors and they face difficulties going higher due to limited length of their cables.

In order to increase our efficiency and flexibility, we have purchased and then modified a relatively lights and self-propelled welding machine. In fact, this welding machine suites W47.1 ticketed welder on construction sites very well. It follows the welder like a vacuum cleaner. So now, welding company in London Ontario can weld on higher elevations without any problems. In fact, JW Portable Welding & Repairs specializes now in these challenging projects.

Moreover, our welding machine crosses easily debris and scaffold located on the top floor. And, our welder can weld all designated spots without stretching long cables on the top floor eliminating significant tripping hazards.

Our machine does not take precious top floor space. Most importantly, it does not preoccupy your crane as it is necessary if you need to relocate the bulky rental welding machine. Furthermore, with additional set of welding cables, we can hit 2-3 floors below the top floor and we can relocate even lower traveling on the stairs. We travel up to Toronto with welding projects on construction sites.

Welding projects in property maintenance, on-site and in welding shop service by welding company in London Ontario

In addition to welding on construction sites we have expended to welding projects within property maintenance and preventative maintenance area. JW Portable Welding & Repairs, a welding company in London Ontario has started to explore this market since 2014. Especially, we have developed expertise to weld cracks, exchange bents and rusted sections of handrails and railing in order to extend their utilization time. More precisely, we focus this service rather on aluminum railing and stainless-steel railing since they are more technologically demanding.  However, we also extend the utilization time of rusted mild steel railings by replacing rusted bottom parts of the railing posts.

Now, we can weld aluminum in windy conditions. Welding repairs of aluminum railing in repair shop environment is done with 5xxx filler rod using Tig. And, for stainless-steel railing we use 308 stainless filler for Tig or Mig. Generally speaking, our railing services, we cover radius of about 150 km from London regarding aluminum railing and stainless-steel railing.

OWSJ reinforcement

Welding of OWSJ reinforcement has come to us an extension of construction industry. Frequently, these projects focus on bottom and top chord reinforcement and web reinforcement. In fact, we have participated in many OWSJ reinforcement projects that included variety of reinforcement elements, reinforcement concepts, and weld types and sizes. Moreover, we have also participated in few inspections prompting some welding repairs after other welders rather rushed approach. In particular, the OWSJ reinforcement welding is rather local operation for us since many mobile welders provide this service.

The welding repairs for heavy equipment operator, machinery trader, heavy equipment trader or heavy machine operator have lifted JW Portable Welding & Repairs from a local welding company in London Ontario to a regional welding company. Specifically, mastering of precision welding cracks combined with advanced high tensile rods has gained us many clients. Moreover, these sophisticated alloy rods have increased our geographical reach. More importantly, impact resistance welding rods and advanced abrasion materials has increased our comparative advantage. Finally, we have become a preferred welding service supplier for number of large size equipment companies and equipment rental business.

In order to improve our welding of heavy equipment services, we have innovated in “fish plate” custom shape and “fish plate” welding technique on top of a welded crack. Also, we have perfected our welding technique and post welding heat distribution to correct misalignment of cracked components. Just this technique alone has caused our name to spread in Sothern Ontario. JW Portable Welding & Repairs, welding company in London Ontario, has started to visit other cities with this specialization. Furthermore, the symmetrical or asymmetrical weld distribution along with concentrated heat distribution technique have allowed us to align sophisticated equipment and machinery. As a designated equipment and machinery welding company, we cover area up to Toronto working for operators, traders and owners. Some dedicated clients drive to our shop 150-200 km with their equipment. Others though, prefer to call as and we will gladly help them on-site.  

Welding repairs of flatbed trailers on Motor Vehicle Inspection Station

The welding repair projects of flatbed trailers on motor vehicle inspection stations have developed as an extension of welding on heavy equipment. Fortunately, our welding techniques and procedures for welding different types of cracks and the ability to weld repair them on steel or aluminum has given us an upper hand in 3 motor vehicle inspection stations closed to the border with Michigan. Since we are a welding company in London Ontario we provide welding services to MVIS in Putnam, Sarnia, and Windsor.

Cool welding projects of damaged cast

JW Portable Welding & Repairs, welding company in London Ontario, repairs damaged casts: cast iron, cast aluminum and cast steel. To clarify, most difficult welds on small damaged cast, we do in our repair shop. However, we also repair large and difficult to move iron casts and steel casts in place and on customer’s site. Moreover, we specialize in repair of aluminum molds. These are very cool welding projects.

Our mobile welding method for damaged steel casts includes constant temperature technique combined with very advanced welding rods or fillers. As of aluminum casts and molds repair, these cool welding projects, depend on aluminum alloy. Particularly, we reduce cost of damaged cast repair by elimination of excessive shutdown costs associated with removal, transportation, and installation of large cast. And we definitely achieve extra-ordinary results.

In order to achieve these extraordinary results for steel casts’ repair, we have innovated with:

  1. temperature monitoring devices,
  2. cast temperature corrections techniques,
  3. cast thermal expansion corrections in ribbing areas, and
  4. multiple specialized welding rods manufactured in North America.

Explicitly, it has quickly become obvious to us, that testing of welding rods suitable for cast iron or cast steel welding is paramount in development of our services. Consequently, only few welding rods has passed our welding company’s criteria.

Specialization of aluminum cast and aluminum mold repair

JW Portable Welding & Repairs, welding company in London Ontario, repairs aluminum casts and aluminum molds according to following factors:

  1. multiple temperature monitoring devices focused on relatively small area for thin aluminum casts
  2. Tig and Mig coordination for large damages, always cool welding projects
  3. heat deflection for significant cracks welding
  4. fabrication of steel support for aluminum mold that diminishes stress in damaged areas. This fabrication of steel support follows in depth analysis of damages and solution scheme recommendations.

Moreover, for cast aluminum welding, we had to add another welding machine with multiple Tig guns to accommodate different aluminum alloys in variety of cast thicknesses. Furthermore, we also had to improve on quality tungsten selection specific to welded alloys in sizes suitable to these casts’ thicknesses.

In addition, the on-site service for damaged large casts allows us to travel with this highly advanced welding service through the whole Ontario including northern Ontario. Clients deliberating to replace the large cast iron, cast aluminum or cast steel are welcomed to inquire about the welding repairs of damaged casts. Although, we are welding company in London Ontario, we will come to your facilities and do this project in place.

Welding repair projects on cracked engine block of luxury cars or semi-trucks

The welding repair projects on cracked engine block of luxury cars or semi-trucks have developed from welding of damaged cast iron, cast aluminum and cast steel sector. Now, this area stands alone with different portable equipment serving this sector. However, the development of multi-layer or extremely thin  cast extensions complicates welding repair projects on cracked engine blocks. Therefore many cracked engine blocks have become the epoxy projects, with extensive epoxy glue applications.

Within this service, we do repairs of damaged cast extensions and damaged threaded holes. But for cracks that have penetrated through the engine block we recommend metal glue seal. With welding repair of cracked engine block, our welding company in London Ontario provides service up to Toronto area. However, noticeably more semi-trucks engine blocks are being repaired by sealing cracks.

Epoxy glue projects that involves corrosion repair, pitting repair and cracks sealing

The epoxy glue projects that involves corrosion repair, pitting repair and cracks sealing on water tanks has developed into a new service area. In fact, these epoxy projects have become more popular due to their lower costs and fairly quick application. Generally speaking, we now offer these epoxy services in situations when we can not use our welding services. As usual, our actions are focused on increase of utilization time of old water tanks damaged by corrosion. First, we use methods to deactivate corrosion at its source and then we repair the damaged spots using epoxy glue. It is important to realize that both types, steel and aluminum, of water tanks are suitable for customized epoxy glue repairs. Most importantly, these epoxy projects save cost of replacing the container or tank and provide additional time for proper planning of the replacement.

Presently, we handle 24 different custom-made epoxy glues with different parameters suitable for different applications. The customization of epoxy glue takes place on-site according to best trade practices. And, handling of shortened live pot epoxy glue is timed for safety. We also offer 16 different additives to the epoxy that enhance the glue’s:

  1. chemical resistance,
  2. impact resistance, and/ or
  3. temperature resistance.

Again, I would like to emphasize that these epoxy projects are very complex and some of them require advance notice. I would like to also emphasize that some of these complex epoxy projects require significant preparation and planning. Welding company in London Ontario covers the area up to Toronto with the corrosion repairs, pitting repairs and cracks sealing on water tanks. Moreover, our clients have used corrosion service on structural elements exposed to chemical corrosion.

More about epoxy projects’ utilization

Epoxy resin application provide attractive solution when project managers faces long term backlog on ordered parts. Custom built machinery and equipment usually requires custom built parts. And, unfortunately, project managers must wait months for such custom parts. When waiting is not a luxury you can afford, then epoxy resin application is your choice.

The portable stainless steel welding in kitchens challenge welder in its welding difficulties and uncomfortable position. Definitely, the grease and steam does not simplify our work. That is why, we have invested in a new modified Mig welding machine for stainless steel. Now, we can weld stainless steel sheet metal up to 22 gauge and make long sealing welds. We have also equipped ourselves with additional custom-made extensions and adapters, as well as custom made tooling.

Using our technological advantage, we can weld leaking stainless-steel sinks, stainless steel tables, stainless-steel brackets in stoves or fridges and some stainless-steel pots on-site. However, more complicated welding such as food steamer crack welding, mixing pot welding that require water seal testing prior welding and after welding must go to our repair shop.
