What is Flash Butt welding?
It is a special type of welding technique where the small parts are welded by high voltage resistance that uses the sectors of the components to combine them together. In this technique, the parts are positioned from end-to-end and get combined with the help of high current density. This can be done by various types of components, such as a bicycle or railway tracks. As an instance, we can talk about Mobile Flash Butt Welding, which is used for railway lines.
How does it work?
The process is done by following the steps mentioned below.
- First, a minor contact between the components is made.
- Then, a high voltage current is flashed to melt the specific regions of the components.
- It is then cooled.
This is how the components are melted and get combined. This is a technique to combine two components together permanently. In most cases, it is done manually, and for doing this, semi-automatic and automatic welding machines are used.
Application Of Flash Butt Welding 
This can be used for joining any type of component, small or large.
On a large scale, this technique is widely used in the railway industry. It is used to create continuous welded rail. As a result, railway lines become much smoother as this welding technique doesn’t allow any gap in between. At the same time, it becomes easy for high-speed rails to run on the lines without being a reason for frequent rail line maintenance.
Except that, it is also used for different other components.
- Used for welding metal sheets, bars, rods, fittings, etc.
- Welding equipment of automotive and aircraft products.
- It is also used to weld household appliances such as refrigerators, chimneys, etc.
- It is used to weld farm implements.
What are the advantages of Flash butt welding?
You may think what the advantages of this welding technique are. Let’s discuss this here. Some key advantages of flash butt welding are written below.
- This process is faster than other welding processes.
- For this, preparation of weld surface is not necessarily required.
- This process requires less power.
- By using the flash welding process, one can weld many dissimilar metals with different melting temperatures.
- This is a comparatively cheap process.
- The strength factor is up to 100%.
- It can weld a whole range of areas or a pointed small section.
- It requires less effort and welding equipment.
- This process allows for fewer contaminants.
- It offers an improved quality of welding work.
- It can be used to weld a large variety of metals, including stainless steel, nickel alloys, Aluminium alloys, iron alloys, and even Titanium.
- Components of different shapes and sizes can be joined.
