One Source Solutions in Metal Fatigue and Welding Defects Repairs, Epoxy Resin Service, Corrosion Protection using Rust Converter to keep the element Corrosion Free

JW Portable Welding & Repairs accommodates our own welding equipment, techniques, welding consumables such as welding rods, wires and abrasives, and more than 24 epoxy resin compounds in order to provide you with the

  1. highest quality service
  2. best quality weld suitable for your project that match your budget
  3. permanent epoxy resin seal of oil, gasoline or water using epoxy resin for metals
  4. rust removal and corrosion protection with second generation rust converter technology to keep the element corrosion free in industrial and commercial settings

The progress of welding technologies can be slightly overwhelming even for professional and certified welder with automated, semi-automated, and manual welding making shocking improvements on annual bases. The consumables, whether rods, wires or abrasives continue to lead the way of welding technology improvements. After visiting the welding show, the analysis of new products can take months. In many cases professional welder becomes surprised that what has been impossible to do only 3 years ago, it is possible now.

 

Metal Fatigue Repairs

The metal fatigue so often observed in heavy equipment repairs, warehousing industry on conveyors, steel ramps, structures of trailers causes metal cracks, splits and abrasion forces cause excessive material thinning. Most welders still use 7018 welding rods to fix metal fatigue’s symptoms such as metal cracks, and they perform this service for the same machines year after year costing owners quite a bit of money. Whereas the high tensile, high impact and surfacing rods and wires improve the metal fatigues much more effectively and efficiently. The combinations of mentioned above welding rods and wires, properly layered high tensile, high impact and surfacing rods, provide a much better protection in metal fatigue areas.

 

Welding Defects Repairs

The welding defects repairs unless referred to missing welds or unsuitable joint preparation should also be fixed with more advanced welding rods and wires. In situations when the welder faces cracked welds, the grinding off the crack and performing the weld with 7018 welding rod assumes the fact that the previous welder who did the original weld that has cracked was not competent in his welding technique. JW Portable Welding always fixed cracked welds with high tensile rods to provide a longer lasting repairs to our clients. The labour cost of a certified welder justifies the use of more advance welding consumables.

Epoxy resin service in Metal Fatigue and Welding Defects repairs

The epoxy resin types and additives change and improve the characteristics of the mass prior and after the solidification. The epoxy resin compounds improvement is surprising and the physical parameters of solidified epoxy is just unbelievable. Many professionals in mechanical maintenance, facilities maintenance, and production think of epoxy resin as a product that changes perspective, how we build machines and other product, how we repair them, and how we preserve components of machines and other products.
JW Portable Welding & Repairs uses variety of custom made by us epoxy resins to mitigate metal fatigues and welding defects in situations when welding is impossible, too costly or will not bring the satisfying effects. In such situations we can provide solutions to your problems even if the elements require vertical or overhead applications of epoxy resins. We can also enhance the abrasion and the impact resistance of variety of elements that are going through a material stress fatigue.
On the other hand if you are faced with conveyors damaging your products and you would like to use a more softer product than HDPE or Teflon, please let us know since we can apply compounds of polyurethane that are much softer than rubber.

Corrosion Protection: Rust Converter and Epoxy Resin to keep the element Corrosion Free for years.

The on-site and in place corrosion protection using second generation rust converter and custom-made epoxy resin always happen in situation when the management discovers corrosion on critical elements within their responsibility. When the element can not be moved to the proper shop for a corrosion treatment that could include metal spray then the corrosion protection service offered by JW Portable Welding & Repairs offers solution to the corrosion problem.
The second generation of our rust converter dis-activates rust and then the suitable layer or multiple layers of epoxy resin rebuilds the element and keeps the element corrosion free for years to come even if the element is steel in contact with the corrosive environment. We also effectively neutralize chemical corrosion and then effectively protect the element from the extreme corrosive chemical environment.
