SPRAY FUSION WELDING
Johnson Enterprises uses a specially designed Oxy Acetylene torch for powder welding. The work piece is heated with the torch. The powder is introduced into the gas stream from the integral powder hopper and then transferred to the work piece through a flame.
EXTREME CARBIDE
This Carbide system is applied by the use of a mig welder hooked up to a carbide canister vibrator. This allows us to rebuild worn parts and at the same time overlay with carbide particles, at desired thickness. These particles come in different sizes from fine to extra coarse, which allow us to apply the size that is needed for the application. This system is applied where there is a lot of abrasive wear. It can be applied on hog hammers, auger blades, etc.
HVOF (HIGH VELOCITY OXYGEN FUEL)
HVOF is today’s standard for applying carbide and metals coatings. High velocity coatings process produces the highest quality carbide and metals coatings available in the industry today!
JET KOTE SYSTEM (COLD PROCESS)
Our experience with this process has proven to have a superior bond compared to chrome (25 thousands of an inch of thickness compared to 10 thousands). The process for Jet Kote is to apply special powders for hard surfacing and build up application. Due to the extreme pressure, it impregnates the powder into the material. It is a cold process, allowing no distortion whatsoever. Some typical applications are hard surfacing pumps, pump castings, chipper parts, planner rolls, built up stainless steel shafting, bearing journals, and many more.

ROBOTIC PTA WELDING (HOT PROCESS)
This specialized Plasma Transfer Arc welding unit is used in the application of a hard surfacing with a variety of different powders. The ID torch enables us to weld inside bushings of all types to increase endurance and acid resistance. Some typical applications are spiral rollers, anvils, pump castings, pump covers, hardface inside housings, piping, valve stem, valve seats, and many more.

HOG HAMMER SCREEN
Hog hammer screens are the main factor in determining the consistency of the finished particle size. The screen is positioned over the discharge opening, ensuring no material evacuates the grinding chamber until it meets the target finished particle size.
Johnson can refurbish or manufacture a hog hammer screen with a special wear plate to enhance the duration and life span.
HOG HAMMERS
Hog hammers are a critical component of a hog mill or grinder, a machine used in the wood processing industry to reduce wood waste into smaller pieces or particles. The hog hammers are typically mounted on a rotating shaft and impact and shred the wood material as it passes through the machine.
Johnson Enterprises manufacture high-quality hog hammers designed to withstand hog mill operations’ high impact and abrasion. We fabricate our hog hammers from high-grade steel alloys with a specialized tungsten carbide coating.
Johnson Enterprises offer a variety of hog hammer configurations to suit different applications and wood types. We design our hammers to be easily replaceable, which helps minimize downtime and maintenance costs.
Johnson manufactures and refurbishes various types and styles of hog hammers by applying our extreme carbide process. It drastically improves their performance and endurance. Customers can rely on Johnson Enterprises for quality hog hammers that will help optimize their hog mill’s performance and ensure efficient and effective wood waste reduction.
Johnson Enterprise provides solutions for the saw milling industry.
