01 Advantages of laser welding machine

Compared with traditional welding technology, laser welding technology is non-contact welding, the operation process does not require pressure, has a fast welding speed, high strength, depth, small deformation, narrow weld seam, small heat-affected zone, and the workpiece deformation is small, the follow-up processing workload is less, reduce the manual output, high flexibility, more safety and other advantages.

Laser welding technology can be used to weld refractory materials such as high melting point metals, and even non-metallic materials such as ceramics and organic glass, with good welding results on shaped materials and great flexibility. For welding inaccessible parts, flexible transmission non-contact welding is performed. The laser beam can be split in time and energy, enabling simultaneous processing of multiple beams, providing the conditions for more precise welding.

02 Points to note on the use of laser welding machines

The following aspects should be noted when using laser welding machine equipment

(a) The position of the welded part needs to be very precise, making sure that it is within the focus of the laser beam.
(b) When the welded part requires the use of a fixture, it must be ensured that the final position of the welded part needs to be aligned with the weld point where the laser beam will impact.
(c) The maximum weldable thickness is limited, penetration of workpieces with thicknesses well over 19mm in the production line requires consultation with the manufacturer to provide more professional technical support.

2.What is Platform automatic laser welding machine?

machine

Platform automatic laser welding machine is an automatic welding machine that uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation is diffused through heat conduction to the interior of the material and the material is melted to form a specific molten pool. It is mainly used for welding of thin-walled materials and precision parts, and can realize electric welding, butt welding, lap welding, seal welding, etc. It has the features of small weld width, fast welding speed, high welding quality, no porosity, accurate control, high positioning accuracy, and easy automation.
3.What is a handheld laser welding machine?
handheld

As the name implies, a manual laser welding machine is a type of welding equipment that requires manual operation. This welding equipment can perform laser welding on long and large workpieces. When welding, the heat affected area is small and does not cause deformation, blackening and marks on the back of the workpiece. The welding depth is large, the welding is firm, the melting is sufficient, and there is no depression in the melt pool where the projection of the molten material meets the substrate.

4.What is the difference between automatic laser welding machine and handheld laser welding machine?

Automatic laser welding machines automatically weld according to a set program after being set up in software; manual laser welding machines, also known as spot welding, are used by users when using laser welding equipment through high magnification to the screen.

Visual spot welding is performed manually and is generally custom manufactured by laser equipment manufacturers to meet the needs of the user. Few manufacturers have stock items. If stock items are available, they are provided to the user as a prototype or proofing reference. More importantly, the power and features of the welding equipment are determined through consultation with the user, and we should also provide the user with a cost-effective equipment product based on the cost of purchase. In what case is it better to use a manual laser welding machine, compared to a fully automated laser welding machine, not only is the purchase cost high, but the maintenance cost is also quite high. The more accurate something is the more important it is for maintenance and naturally the higher the cost. In addition, fully automatic laser welding mainly concentrates on the CNC automation of the work platform, which requires high functionality and versatility of the work platform, but in practice, this is not a panacea, and many switches different products can not be used, which limits the role of automatic laser welding machine. Today, we focus on manual laser welding machine, so the manual device naturally solves the above problems. Its welding function is to perform welding operation by handheld laser welding joint with various control angles, so it can be said to be a non-custom laser equipment to adapt to the welding of many shapes and angles of products. As long as the power is high enough, it can adapt to the welding of most products

products

The productivity of manual laser welding machines is certainly much lower than that of fully automated equipment. However, for decentralized processing or non-large-scale processing and welding of production plants, manual laser welding is more advantageous. There is no need to configure a welding table and avoid the problem of large floor space. In addition, small workshops weld a wide variety of products with irregular shapes, so manual laser welding can fully meet the needs of such production and has a good adaptability.

Manual laser welding without precision welding table, low consumption of consumables and low maintenance cost of equipment. Generally speaking, we need to maintain more workbenches, while manual laser equipment can complete the operation as long as it is equipped with portable laser welding joints. Easy to replace, low cost of replacement parts. If you don’t know how to replace them, you can give them to the manufacturer for direct maintenance without worrying about shipping.

The difference between automatic laser welding machines and manual laser welding machines is shared here. Many people may think that an automatic laser welder is better because it is automatic, but the truth is that the two types of equipment are used for different purposes and each has its own advantages. In the selection process, we also need to choose the right laser welding equipment for our production according to our actual needs.
