Carbide Welding Rod – The Ultimate FAQ Guide

Finding the best carbide welding rods in the market is not an easy thing to do. Because of the many different options, it became something that’s special and hard-to-find at the same time.

But what is a carbide welding rod really? How can you use it to gain an advantage? Today, we’ll discuss everything you need to know about carbide welding rods – what is it exactly, how you can use it, where you can find it, and so on.

Before we do so, let’s dissect it first. Let’s find out what both “carbide” and “welding rod” means.

What is Carbide?

Carbide is a compound that is made up of a kind of metal and carbon. However, there are some sources that say referring to “carbide” alone is incorrect.

What is Carbide

Because it’s carbon and another ingredient, ”carbide” alone is not the right way to say it. The most common metal associated to it is tungsten.

So, when you hear something like carbide welding rod, it can be any type of metal + carbon.

What is a Welding Rod?

Welding Rod

welding rod is a material you use to fuse two pieces of metal together through welding.

It’s one of the many different types of welding electrodes in the market.

What is Carbide Welding?

Carbide welding is the procedure of melting a carbide material to be fused to another material.

Carbide Welding

You can use it for any of the following processes:

  • Hardfacing;
  • Cladding;
  • Weld Overlay; or
  • Any other type of procedure that involves welding

Understanding What Carbide Welding Rods Are

Carbide welding rods can be any type of compound (carbon + metal) you can use for welding.

Tungsten Carbide Welding Rods

One of the most common examples of a carbide welding rod is Tungsten carbide. Others would include titanium carbide, vanadium carbide, etc.

You would use them as an electrode to assist the welding procedure; they’re what’s deposited and melted.

What is a Tungsten Carbide Electrode?

It’s an electrode, meaning, it can be a rod, a wire, etc.

Tungsten Carbide Electrode

tungsten carbide electrode is the material made out of tungsten that you can use to fuse metal pieces together.

How is Tungsten Carbide Made?

You can create tungsten carbide by using the Powder Metallurgy procedure.

Tungsten Carbide Made

It’s when you heat powdered tungsten and mix it with cobalt, while pressure is applied.

Creation of Carbide Welding Rods

The process on how you can create tungsten carbide welding rods is:

Ball Mill
  1. Preparation of raw materials
  2. Utilization of the ball mill (combination of raw materials)
  3. Finished product from ball mill enters suppression chambers
  4. Inspection of the product
  5. Machining after inspection
  6. Sintering or shaping of the product

What is the Process of Hardfacing?

Process Hardfacing

It’s the procedure where material is deposited to the base metal. You can perform hardfacing through any of the following processes:

  • Welding processes
  • Spray fusing
  • Thermal sprays

The Goal of Hardfacing

The purpose of performing hardfacing is to prolong the life of that part or material. Also, you can find it beneficial in multiple ways, including:

  • Creating a wear-resistant material
  • Restoring a worn-out surface
  • And many more

Tungsten Carbide Hardfacing

This is the process of hardfacing a part or component using tungsten carbide.

Tungsten Carbide Hardfacing

It is advantageous because the properties of tungsten carbide are embedded to the base metal. When you perform tungsten carbide hardfacing using carbide welding rods, you can expect:

  • Highest levels of abrasion resistance
  • Great resistance to wear
  • Moisture resistance
  • And so on

Composites Used in Tungsten Hardfacing

To be able to perform tungsten hardfacing, you would need machines and equipment. They can be anything from a tungsten feeder, SMAW welding machines, and so on.

Apart from that, you also need tungsten carbide welding rods or electrodes. This will be where you’ll get the properties from, to transfer to the part or component.

Applications For Tungsten Carbide Welding Rod

You can apply tungsten carbide welding rods to many different things. Some of which include:

Tungsten Carbide Welding Rod Applications
  • Engineering Equipment and Machinery
  • Mixer Blades
  • Coal Mine Chutes
  • Mining Machinery
  • Hardfacing Tools and Equipment
  • Coal Mine Drills
  • Oil Drilling Tools
  • And Many More

As you may have noticed, it’s common in applications where wear and abrasion is rampant. Its properties make tungsten carbide welding rods an effective addition to it.

Features and Properties of Carbide Welding Rods

High Hardness

Properties of Tungsten Carbide Hardfacing

Tungsten carbide welding rods are known for their high hardness.

It sits between 9 and 9.5 on the Mohs scale of hardness, making them one of the hardest materials you can use.

Corrosion and Abrasion Resistant

In addition to that, they’re also known to be attacked only by some mineral acids.

They’re perfect for all your abrasion and corrosion-resistance needs if you’ll use them in chemical or marine applications.

High Pressure and Temperature Resistance

You can use tungsten carbide welding rods even in high pressure and temperature areas. You’ll never have the fear of deformation and deterioration.

Those are just some of the most common properties and features of carbide welding rods. There are others and that would depend on your application.
