CRA Weld Overlay Cladding – The Ultimate FAQ Guide
Corrosion is one, if not the biggest enemy of steel and metal. It is a big problem for machines and equipment, especially those that are chemically exposed.
Being in the industry, what are the specific things you need to fight it? What processes and should you do to avoid corrosion?
This post will be all about learning what CRA weld overlay cladding is. What is it, how it can help, and what benefits and advantages it can give.
What Does CRA Stand For?
CRA is an abbreviation for Corrosion Resistant Alloy. It’s a material that has high resistance power in blocking corrosion.
It’s an adjective to describe workpieces or surfaces that have undergone CRA processes.
What is CRA Material and Where Is it Usually Used?
They are reinforced materials that have properties, excellent in resisting corrosion.
Normally, they’re used in industries where corrosion is most common. The most common industry susceptible to it would be the Oil & Gas Industry.
What is a Cladding Material?
Clad material is also known to be the CRA layer. This is the layer added to the surface, improving its resistance against corrosion.
At the same time, it improves the base metal’s desirable properties promoting strength and durability.
What is CRA Weld Overlay?
It’s a welding process that extends the lives of parts or components that are prone to corrosion.
Furthermore, you could also use them in situations where procedures can corrode materials.
What is CRA Cladding?
Cladding is the process of depositing materials to strengthen the exterior of a surface.
CRA cladding would involve deposition of CRA material to a part or component. The goal of CRA cladding is to make parts and components resistant to corrosion.
Is Chromium the Most Corrosion Resistant Element?
No, Chromium isn’t the most corrosion resistant element. Iridium is the most corrosion-resistant element of all.
For metals, though, you can find that both Tungsten and Iridium are the most resistant to it.
What Causes Corrosion in Metal?
Corrosion happens when metal reacts with a different substance like Hydrogen or Oxygen.
When it reacts, the atoms on the metal surface oxidize, which then forms corrosion. This does not only damage the exterior or the surface, but also reduce its capacities.
What are the Effects of Corrosion to Your Parts or Components?
There are numerous effects corrosion can have to your metal or steel.
Some of the most common ones include:
Loss of Strength
Corrosion isn’t only ugly-looking; it can also have adverse effects on the strength of parts, too.
In fact, they can make metallic surfaces structurally weaker due to:
- The reduction of flexural strength
- Relevant decrease in axial strength
Significantly Decreased Bond Strength
When a certain steel or metal corrodes, corrosion products widen and expand.
This can reduce the capacity of the corroded section, reducing its overall bond strength.
Reduction of Ductility
Due to some properties, metals are known to be ductile and malleable materials.
When corrosion consumes a part or a component, it greatly reduces ductility altogether.
Loss of Value
The structural degradation that it has could downgrade the value of machines.
Because of its undesirable physical effects, it can translate to being invaluable in the long run.
These are just some of the most common effects that corrosion can do to metallic parts and structures.
What is a CRA Clad Pipe?
A CRA clad pipe is a material that is comprised of CRA-rich properties and steel pipes. You can make them through welding or other mechanical processes.
You can use CRA clad pipes in the Oil & Gas Industry because those are the most prone to corrosion.
The CRA Material List
CRA alloys that are the least prone to corrosion include, but are not limited to:
- Chrome and Chromium
- Stainless Steel
If you use and combine them to other metals, you can promote corrosion resistance.
The resistance would be even greater than corrosion-resistant components such as carbon steel, and the like.
How Can CRA Weld Overlay Help You?
By performing a CRA weld overlay, you can stress less about your parts being corroded.
You’d want to use this process to achieve the following things:
- To improve the service life of metallic parts and components
- Protection even in the most corrosion-prone situations and processes
- More efficient and productive processes from your metallic parts and components
Those aren’t just the benefits you can get from the CRA weld overlay cladding process. There are a lot more!
What is the CRA Overlay Process?
The CRA overlay process is the deposition of corrosion-resistant alloys through welding.
You can accomplish it by using or utilizing different welding processes, which may include:
- Submerged Arc Welding (SAW)
- Flux-Cored Wire Process
- Plasma Transferred Arc Welding (PTA) Welding
- Shielded Metal Arc Welding (SMAW)
- Metal Inert Gas Welding (MIG)
Which Industries Need the CRA Weld Overlay Process?
The industries that would benefit the most from CRA weld overlay would be those that perform operations and utilize chemicals and fluids.
Moreover, high temperature and high stress situations can also benefit a lot from it. The most common industries prone to corrosion are, but not limited to:
- Chemical Processing Industry
- Paper and Pulp Industry
- Offshore and Marine Industry
- Oil & Gas Industry
- Nuclear Industry
- And Many More
