Welding application of precision laser welding machine on fire extinguisher tank

In the prior art, the well-known technology is that most of the fire extinguisher tanks are made of steel plates. First, the steel plates are rolled into a cylindrical shape, then upper and lower heads are installed at both ends, and then the tank is welded to make the upper The head and the lower head are tightly combined with the tank body.

The traditional welding method of welding fire extinguisher cylinders has a large weld seam, which is easy to deform the surrounding of the welded product, and there is welding residual stress after welding, which will produce pores and slag inclusion, which is not suitable for use on fire extinguishers. Laser welding topsunlaser.com cylinder welding The seam is exquisite, the speed is fast, the depth is large, and the deformation is small, so it is widely used in the welding of fire extinguisher cylinders.

The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool to complete the welding.

Fire extinguishing equipment is a must-have item for firefighting that is often neglected by others and can be used when it is urgently needed. Especially in today's high-rise buildings, with a lot of wood, plastic, and fabric decoration, once there is a fire, if there is no proper fire extinguishing equipment, it may cause a catastrophe. Therefore, fire extinguishers are very important for us. It is a kind of tool, so its welding quality is also crucial.

Laser welding is to irradiate a laser beam with a high energy density on two parts of the material, so that the parts are heated and melted, and then cooled and solidified to form a whole. Compared with the traditional welding process, laser welding has the following advantages:

1. Non-contact processing, no external force on welded parts.

2. The laser energy is highly concentrated, the thermal influence is small, and the thermal deformation is small.

3. It can weld metals with high melting point, refractory and difficult to weld, such as titanium alloy, aluminum alloy, etc. Welding between certain dissimilar materials can be achieved.

4. The welding process does not pollute the environment, it can be directly welded in the air, and the process is simple.

5. The welding spot is small, the welding seam is narrow, neat and beautiful, no need to deal with or only a simple treatment process after welding. The weld structure is uniform, the pores are less, and the defects are less, which can reduce and optimize the miscellaneous parent material. The mechanical strength of the weld is often higher than that of the base metal. The mechanical properties, corrosion resistance and electromagnetic properties of laser welding are superior to conventional welding methods.

6. The laser can be precisely controlled, the focusing spot is small, and it can be positioned with high precision to achieve precision machining.

7. It is easy to cooperate with computer numerical control system or manipulator and robot to realize automatic welding and improve production efficiency.
