What is Flame Spraying (FLSP) in Welding?

Flame spraying is a thermal spraying process in which an oxy/fuel gas flame is the source of heat for melting the surfacing material. Compressed gas may or may not be used for atomizing and propelling the surfacing material to the substrate.

The flame spray process can be used to apply a wide variety of materials, including:

metals,
ceramics,
and polymers.

What is spray welding used for?

Flame spraying is commonly used to apply coatings for wear resistance, corrosion protection, and electrical insulation. Flame spraying can be used to apply coatings to both flat and contoured surfaces. The flame spray process is versatile and can be adapted to a wide range of production requirements.

Advantages of Flame Spraying (FLSP)

The main advantages of flame spraying are:

It is a rapid process with a high deposition rate.
A wide range of materials can be applied using this process.
Flame spraying can be used to coat both flat and contoured surfaces.

Disadvantages of Flame Spraying (FLSP)

The main disadvantages of flame spraying are:

It is a difficult process to control and replicate.
There is a high risk of defects and imperfections in the coatings.
The process can be dangerous if proper safety precautions are not taken. Flame spraying is a thermal spraying process in which an oxy/fuel gas flame is the source of heat for melting the surfacing material.
