Operating heavy equipment in the steep challenging terrain and weather of British Columbia comes with its share of accidents and breakdowns. In the construction, forestry, and mining industry, nothing cripples a site like a broken machine. When it comes to fixing broken steel in the field, we have the tools and expertise to get you back up and running quickly and efficiently.
Our welders work hard and fast to:
1. Cut and remove the failed components. This can be done with oxy-fuel, plasma cutting or carbon arc gouging. Our skilled tradesman will assess this on a case by case basis.
2. Prepare the new joint/part. Choosing the correct replacement/filler material is crucial. All components should be replaced with a material that meets or exceeds the strength of the original material. Each application varies in mechanical properties such as required strength, wear resistance, impact strength and tensile strength. An exact match ensures weld quality and longevity, and avoids future failure and unwanted downtime.
This current downtime also provides an excellent opportunity to reinforce trouble/weak spots. A part breaking in the same place more than once might mean it needs to be reinforced with additional steel.
3. Weld, repair and cleanup. The two most common processes for field welding repair are Shielded Metal Arc Welding (SMAW or Stick); and Flux Cored Arc Welding (FCAW). Stick electrodes are self-shielded, as are many Flux Cored wires for this application. Self-shielded processes cut down on the amount of time and equipment needed; there is no need to haul in a gas cylinder, hose and regulator.
WITS mobile welders get you back in the game when you need it the most. We also offer emergency call out services.
Some of the most common repairs and call outs requested are:
Metal equipment parts can go through significant stresses, abrasion, and wear that can impact the integrity and lifespan of the structure. Hardfacing or hardsurfacing is the technique of welding a wear-resistant portion of material onto the part’s surface, which extends the life of the piece. With this in mind, hard-surfacing not only extends the service life of used parts, but can be applied to new parts to give them added protection. In harsh environments and demanding projects, this relatively simple application can push the service life of your equipment and bring a net benefit to your operations.
