The range of laser welding machines is very wide. All metal materials are suitable for welding by laser welding machine. Stainless steel is the best material for welding. Aluminum, copper, etc. have high metal reflectivity and alloy composition. For ordinary laser welding, explosions are most likely to occur with high zinc content. So can aluminum be welded with a laser welding machine? The following will be explained by the technicians for you:

The lattice pattern of the laser welding machine determines the material to be welded. A good spot weld pattern can weld a wider range of materials and achieve better results. Laser welding machines not only have the advantages of many traditional welding methods, but also can weld many special materials, with many advantages such as cost saving, high quality, fast speed, and smoother welding area.

It is an ideal laser welding tool that can completely replace the traditional spot welding machine.

Cost savings – no expensive fixtures required.

Fast – Welding is twice as fast as conventional spot welding.

High Quality – Higher weld strength and hardness can be achieved based on reliable weld quality at the wire.

Flatter – Compared with spot welding, it can effectively reduce the protrusion of the welding area; all-round – welding special materials is safer.

How much is a small hand-held laser welding machine

In manufacturing and other consumer markets, laser welding machines can replace traditional resistance spot welding machines. At the same time, the laser welding machine can realize aluminum materials that cannot be welded by traditional spot welding machines, ensuring perfect welding quality. Laser welding machines have many advantages and have broad application prospects.

What problems should be paid attention to in the use of laser welding machine?

Laser welding machine is also often referred to as laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc. The energy laser pulse locally heats the material in a small area. The energy of the laser radiation is diffused into the material by thermal conduction, causing the material to melt to form a specific molten pool.

Laser welding is mainly aimed at the welding of thin-walled materials and fine parts, and can complete spot welding, butt welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, small heat affected zone, large deformation, and fast welding speed. The welding seam is smooth and beautiful, and no treatment is required after welding. It can be precisely controlled, the focusing spot is small, the positioning accuracy is high, and it is easy to complete automation.

So, what problems should be paid attention to in the use of laser welding machines?

 

Lasers have the same biological effects (cooking effects, light effects, pressure effects, and electromagnetic field effects) as ordinary light. This biological effect, while beneficial to humans, can also cause damage to the eyes and skin if unprotected or poorly protected. As well as direct or indirect damage to human tissues such as the nervous system. In order to ensure the safety and protection of laser welding machines during operation, laser damage must be strictly controlled, and engineering control, personal protection and safety management must be done well.

Engineering control of matters needing attention in use of laser welding machine

The engineering control of laser welding machine precautions refers to the safety measures taken on the structure of the laser or laser welding machine, mainly including: protective cover – to prevent the operator from exceeding the maximum allowable exposure; safety interlock – finger and protective cover Attached automatic device to prevent radiation when the shield is removed; safety light path – light path that may cause burns or secondary radiation to shut down; key switch – generally refers to removing the key, laser turning; beam stop – to prevent laser light Beam beyond the controlled processing area, a beam stop or attenuator can be used.

Personal protection precautions in the use of laser welding machines

Personal protection in the use of laser welding machines mainly refers to wearing fire-resistant and heat-resistant laser protective clothing, laser protective glasses that can selectively attenuate specific laser wavelengths, laser protective masks and accessories for ultraviolet laser sources. Wear laser protective gloves to prevent damage from direct or scattered laser light.

Personal protection and safety management of matters needing attention in use of laser welding machine

The use of personal protection and safety management precautions for laser welding machines mainly includes the establishment of specialized agencies or personnel to clarify responsibilities and rights: including safety training and supervision.

The laser welding machine has a high degree of automation and a simple welding process. Non-contact operation can meet the requirements of cleanliness and environmental protection. Using laser welding machine to process workpiece can improve work efficiency, finished workpiece has beautiful appearance, small welding seam, large welding depth and high welding quality. Laser welding machines are widely used in the processing of dental dentures, keyboard welding, silicon steel sheet welding, sensor welding, battery cap welding, etc.
