Application of laser welding machine on metal fire extinguisher tank

Fire extinguishers are one of the most common fire protection facilities. They are stored in public places or where fires may occur. Different types of fire extinguishers contain different ingredients and they are designed for different fires.

Fire extinguisher is a kind of fire fighting essential which is often neglected by others, but it needs to be displayed when needed. Especially in high buildings, indoors there are a lot of wood, plastic, fabric decoration, once there is a fire, without proper fire-fighting equipment, it will cause a major disaster. Therefore, fire extinguisher is a very important tool for us, its welding quality is also crucial.

Among the technologies available, the well-known technique is that the fire extinguisher tank is mostly made of steel plate. First, the steel plate is rolled into a cylindrical shape, and then the upper and lower heads are installed at both ends, and then the can body is welded to make the upper head and the lower head are tightly jointed to the can body.

The traditional welding method to weld fire extinguisher cylinder has large weld seam, which is easy to deform, and there are welding residual stresses after welding, which will generate pores and slag inclusions, which are not suitable for using on fire extinguishers. While the laser welded steel cylinders are beautifully welded. It is widely used in the welding of fire extinguisher cylinders because of its fast speed, large depth and little deformation.

The Laser welding machine uses a high-energy laser pulse to locally heat the material in a small area. The energy of the laser spreads to the inside of the material through heat conduction, and the material is melted to form a specific molten pool to complete the welding.

Shenzhen Sunlaser's metal laser welding machine welding fire extinguisher tank has a high degree of automation, simple welding process, and the non-contact operation method, which can meet the requirements of clean and environmental protection. Process workpieces with laser welding machine can improve work efficiency. The finished workpiece has beautiful appearance, small weld seam, large welding depth, high welding quality. And it can weld the hard-to-reach parts by using non-contact long-distance welding with great flexibility.
