Welding Companies and welding shops use different methods to repair wear on their equipment. Some welding companies opt to remove the worn areas of there equipment and use AR- Plate, and weld in new sections using Low -hydrogen electrodes. This method can produce faster results than using Electrodes or the MIG welding process to hard surface the worn areas. Using Hard surface instead of replacing the worn sections can add a tougher more wear resistant section. Because you have a choice of different types of hard surface available. Depending on your wear application this can be a much better choice to repair your worn equipment.
Let&#;s talk about the types of welding processes available to repair worn equipment.
If you refer to our welding rod chart you will discover many different types of hard surface electrodes and mig wires to correct the wear on your equipment.
Wear is a result of many different applications. It is very important to use the proper Hard surface. Wear on equipment is caused by different applications, severe abrasion, moderate to heavy impact or chemical reaction.

also, it is important to use either the right electrodes or Mig welding process to repair your application. Depending on your welding ability and welding equipment you have available, there are many different types of electrodes and mig wires to solve your wear issues.
To repair wear on most heavy equipment both the mig welding process and electrodes are commonly used. when you hard surface you need to know what the depth of the wear is before you start the repair. This is very important to determine. When you purchase hard surface electrodes or mig wire there are two types in general terms build-up or hard surface. If you determine your wear would need multiple passes, then you would purchase build-up electrodes or mig wire. Build-up electrodes and mig wire have an Rc of 25-35 which is soft but work hardens and can be machined or ground with little effort. This build-up is used for multiple passes to repair the wear back to normal size. It is also a good practice to cap the built-up area with two passes hard surface electrodes or hard surface mig wire. Hard surface electrodes and mig wires have an Rc of 52-65 as deposited. This means you would never build-up with a hard surface. This is a very important point you risk cracking and breaking off of the hard surface if used to build-up risking damage to your equipment.
It is very important to make sure you are purchasing the proper hard surface for your application. Most Industrial gas companies stock the basic welding electrodes and mig wires. If you visit your local industrial gas supplier for hard surface and they do not ask what your application is, then ask what type of hard surface they are given you. As we talked about in the previous paragraphs that there are many different types of wear. So it&#;s important to get the proper product for your application.
Let&#;s discuss stick welding amperage. This is very important when you are using a hard surface. You need to be aware of how much heat you want to apply to the base metal. How much distortion from the heat can you allow?
Do you need to weld out of position? Is your hard surface electrode made to weld out of position? There are products on our welding rod chart that will solve these hard surface issues.
When you look at our welding rod chart you may not recognize the welding rod numbers. They are proprietary to our company. On our website, you can see the description and MSDS specification of all our products.
We hope this article has helped you with your hard surface applications. If you have any questions about your application, please call our Technical helpline @ 1-888-935- or [ protected]

1. What is flexible welding rob/wire&#;
Cemented carbide flexible welding wire is a kind of soft welding wire, which uses cast tungsten carbide powder, spherical cast tungsten carbide powder or a mixture of the two as the hard phase, and uses nickel-based alloy powder as the bonding phase, which is mixed and bonded in a certain proportion. It&#;s extruded, dried and manufactured soft welding wire with a hard metal core in the center.&#;which is suitable for oxyacetylene welding, with excellent flow and form control at low deposition temperatures around °C. The nickel-based alloy in the product gives the cladding layer excellent corrosion resistance. They are excellent flow and wetting properties. Flexible welding ropes normally refer to Cast Tungsten Carbide Welding Rope and SCTC Welding Rope (Spherical Tungsten Carbide Welding Rope). GSN-1 is a 5mm diameter cast tungsten carbide welding rope, manufactured by mixture of CTC( Cast Tungsten carbide) and Nickel wire covered by self-fluxing Nickel alloy. The cast tungsten carbide is with good wear resistance. The performance of this kind of welding rope possesses makes it suitable for welding on petroleum drilling tools, concrete mixing blade, mud pump, coal sluice, coal drill pipe, tunnel drilling machinery to stand severe working environment or conditions and extend service life accordingly. Recommended application method is Oxy-Acetylene Welding with weak carburizing flame.
2. What are the applications&#;
Welding wire can be used in all steels except manganese steel surfacing on all steel substrates, but not recommended on cast iron. These Products perform well in harsh environments, typical applications include:
Stabilizers and other oilfield equipment
Drilling machine
Thruster
Mixing plates for brick and clay making
Food and chemical processing decanters
3. What is a Welding Wire?
A welding wire or an electrode is the material used to weld and fuse different pieces together. Usually bought in a form of a spool, it&#;s what generates the heat. Therefore, it is what&#;s responsible for the fusion of 2 different parts and components.
4. What is a Hardfacing Wire?
Hardfacing wires are technically the same thing as welding wires; just different terms. It&#;s only referred to as hardfacing wires when they&#;re used for hardfacing, not welding. But, for you not are confused, they are the exact same thing.
5. Flexibility and Repair Versatility
The company is the world’s best Hardfacing for Cement Plant Equipment supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Because of its flexibility, you can use it in a wide range of applications.
In fact, it&#;s seen as the best solution for hardfacing because of its properties.
However, the most typical of all applications it can be used in involve the following processes:
Improvement of the Corrosion and Abrasion Resistance of Parts and Components.
Hardfacing of High Impact Parts like Fuel Mixer Blades, Conveyor Screws, and Pumps.
Increasing Hardness of Heavy-Impact Machineries and Equipment
6. Is Welding Wire and Welding Rod the Same?
No, welding wires and welding rods are two different materials.
They differ in size and in shape; welding wires are just thin pieces of wires. Furthermore, they&#;re sold in spools.
Welding rods, on the other hand, are thick pieces of metal you use for welding.
7. What are the Pros of Hardfacing Welding Wires?
Using welding wires for hardfacing gives you the following advantages:
Cost effective
Relatively cheaper than other methods
Gives the product the hardness and the toughness it needs
Higher and better rates of deposition
8. What are the Cons of Hardfacing Welding Wires?
There also are some disadvantages of hardfacing welding wires and they include:
Lower deposition rate
Weaker efficiency
Welder experience should be topnotch
To achieve the best results, automated systems should be taken into account.
