Spray transfer welding is one of the fastest growing welding technologies in the world. With increasing global demand for lighter, stronger and faster welding than traditional methods, it is clear why spray transfer welding is becoming more popular. The process yields superior weld penetration, increased weld speed and an overall better outcome than manual welds or MIG welds.
Spray transfer welding is renowned for its strength, quality and cost effectiveness. To date, some 10 million welds have been completed using spray transfer welding, making it a widely adopted technological solution.
What is Spray Transfer Welding?
Spray transfer welding, also known asshort circuiting spray, is a welding method that uses a wire feeder to feed the wire continuously into an arc.The arc is created between the wire and the surface to be welded. The arc melts the wire, which enters the weld puddle in discrete droplets, resulting in a smoother, flatter, and stronger bond. This type of welding is often used for work on aluminum and stainless steel.
How Does Spray Transfer Welding Work?
In spray transfer welding, a welding wire is fed continuously to the arc during welding. This wire is typically made from stainless steel or aluminum.As the wire enters the weld puddle, it melts and forms a fine spray of droplets, resulting in a smoother and flatter weld profile and stronger bond. The wire entering the weld puddle is always cooler than the weld puddle itself, so the heat of the weld puddle is partially “transferred” to the wire.
This helps to reduce welding distortion and spatter while providing an improved weld profile.
Advantages of Spray Transfer Welding
Spray transfer welding has a number of advantages, including:- It provides a smoother and flatter welding profile
- It helps to reduce warpage and distortion during welding
- It helps to reduce spatter during welding
- It produces a stronger bond than other welding methods
- It is compatible with a wide range of materials, including aluminum and stainless steel
Disadvantages of Spray Transfer Welding
Spray transfer welding has a few drawbacks, including:- It requires specialized equipment, making it more expensive and difficult to use than other welding methods
- It is more difficult to use than other welding methods, so operators must be better trained and more experienced for high-quality welds
Conclusion
Spray transfer welding is an advanced welding method that provides a smoother and flatter weld profile, reduces distortion and spatter, and produces a stronger bond than other welding techniques. It requires specialized equipment and higher skill levels from operators, so it can be difficult and expensive to use.However, when used properly, it can provide superior results.
