What is the Definition of Hardfacing?
It’s a welding procedure that you can apply to parts that are already damaged or worn-out.
You can use it for restoration, rebuilding, enhancement, and even rehabilitation.
What are Hardfacing Machine?
Hardfacing machine is equipment that you can use to accomplish hard surfacing treatment.
You can find many different types of hardfacing equipment – we’ll discuss those below.
Different Hardfacing Patterns
You can set various hardfacing machines to perform different hardfacing patterns.
The primary patterns for hard surfacing are:
Choosing the pattern would depend on the type of abrasion, material causing the abrasion, and the wear location.
Can Hardfacing be Done With Hardalloy Stick Electrode?
Yes, in fact, hardalloy sticks electrodes are considered as the best base for hardfacing.
Due to its properties of it being safe; adding the fact that it offers excellent durability, it’ll be perfect for the integration of a new protective layer.
Can I Use Hardfacing MIG Wires For Hardfacing?
Absolutely! However, there are certain hard surfacing machines and equipment that don’t feed off of wires.
So, you have to make sure that you’ll use a hardfacing machine that allows it.
Different Hardfacing Welding Methods
For hardfacing, you can utilize and employ almost all welding methods. You can choose to use:
- Gas Metal Arc Welding (GMAW)
- Shielded Metal Arc Welding (SMAW)
- Submerged Arc Welding (SAW)
- Plasma Transferred Arc Welding (PTAW)
- Oxyfuel Welding
- And So On!
Similar to the welding wires, you need to look for equipment that are capable of these methods!
Factors to Know Before Purchasing Hardfacing Equipment
Before you decide which hard surfacing machine you need, it’s imperative that you know a couple of factors and characteristics of them first.
- Control System (Is it hard or easy-to-understand?)
- Maintenance requirement
- Flexibility and versatility
- Water cooling effect (Coes it have one?)
- Flux Feeding (Does it have one?)
Are There Different Hardfacing Techniques?
While there could be more, the two primary techinques of hardfacing are: overlay (welding) or build-up.
Build-up is a technique you use to rehabilitate or restore old parts and components. It’s like to restore the dimensions of it.
Overlay is the procedure you do to protect the part or component from all the types of wear it can undergo.
Types of Hardfacing Machines or Equipment
You can choose from a wide range of hardfacing equipment. There are:
These are machines you can use to hardface from within and outside the wall.
One-head hard surfacing machines have operational ability for humans, but have processes in automation; it’s the same with two heads.
The only difference would be with the number of welding heads for hardfacing.
These are hard surfacing machines that utilize plasma transferred arc (PTA) as the welding process to complete the procedure.
Aside from these, there are many more machines you can use for hard surfacing.
Different Hardfacing Welding Rods
Various hardfacing welding electrodes can be categorized into three (3) groups: Cobalt base, Nickel base, and Iron base.
Depending on the hardfacing machine you’ll be using would dictate the type of electrode it’s compatible with.
Can Hardfacing be Done for Longevity and Strength?
Yes! In fact, those are two (2) of the primary uses of hardfacing.
Since the process is used to deposit material to the surface, you can use it to enhance the durability and the strength of your part or component.
This allows it to absorb more impact.
Furthermore, it can also add to the lifespan of a part, making it resist more actions.
Excavator Bucket Rebuilding and Hardfacing
Because of their nature, excavator and loader buckets undergo the wear-and-tear process faster.
Performing hardfacing can allow them to be more durable and longer-lasting! You can apply it on both the interior and the exterior of the buckets for rebuilding, restoring, or enhancing.
Hardfacing Electrode Number
The numbers on the electrode have meanings – they’re not just a bunch of random numbers.
Comprised of a letter and a 4 or a 5-digit number, here are their meanings:
- Letter (Prefix E means that it’s an arc welding electrode)
- First two (2) digits (of a 4-digit number) and first three (3) digits (of a 5-digit number) determines the tensile strength (at the minimum).
- Third (3rd) digit (of a 4-digit number) and the fourth (4th) digit of a (5-digit number) is a sign of the welding position.
- The last number is what describes the type of coating that you can use with the electrode.
Before purchasing an electrode, make sure that you know your hardfacing machine well. Using a different or an incompatible electrode can mess up the workpiece.
