Flash Welding
Flash welding is a welding technique that is quick and effective and used in numerous industries when joining two metals together. The strong bond is created by carefully heating and fusing the ends of two metal parts. The heat causes the end of the metal pieces to melt and produce a pool of molten metal and extra material, which is known as “flash,” is forced out of the joint. The other name for the same is flash butt welding. In this, the workpieces are subjected to electrical current before being brought together, which causes an arc to form.
Key Features of Flash Welding
- Process: The process involves the usage of the ends of the workpieces to melt to form the joint instead of melting the entire workpiece.
- Mechanical Pressure: Workpieces are subjected to mechanical pressure so that a strong bond is formed, which causes extra material to be expelled and a clean joint to form.
- Flash Formation: High temperatures are produced as an electric current passes over the contact area, melting the metal and the extra substance is discharged as a molten flash.
- Flash removal: After the connection has been produced, the extra material of the flash is usually removed mechanically, such as by shearing or cutting, leaving a neat and strong bond in its place.
What is Flash Welding ?
Flash welding, sometimes referred to as flash butt welding, is a type of welding in which two pieces of metal are joined by first melting their ends together and then hammering them together. Its benefits include high joint strength, little stretching, and the absence of consumables, which are frequently needed in traditional welding techniques. In this article, we’ll learn about flash welding, its features, parts, working, applications, advantages, disadvantages, and the difference between flash welding and butt welding with frequently asked questions. Hence we will say that is it a type of resistance welding that is done without the help of the filler metals.
