Laser Welding

Application of laser welding in various industries

A laser welder, often referred to as a laser welder or laser welding machine, is used for laser material processing. Laser welding uses high-energy laser pulses to heat the material in a small area locally. The energy from the laser radiation is diffused into the material by heat conduction, causing the material to melt and form a specific molten pool. So, what are the main industries where laser welding machines are used?

Battery industry

New energy vehicles power battery

The cost of modern energy vehicles is primarily made up of their power batteries, which make up 30% to 40% of their overall cost. Welding is a crucial industrial technique in the production of power batteries, from cell manufacturing to PACK assembly. Steel, aluminum, copper, nickel, and other materials, in particular, are found in various places in the structure of the power cell. These metals can be fashioned into housings, cables, or electrodes.

Therefore, whether welding between one or multiple materials, laser welding can work perfectly with the laser beam’s excellent directionality and high power density. The advantages of laser welding lie in new energy power cells. Industry to the extreme!

Mobile phones and other digital products' battery

Cell phones and most batteries for coding products are laser welded. A laser welding machine combined with an automatic table can weld beautiful lithium and aluminum batteries efficiently and environmentally friendly.

Automobile manufacturing industry

In the automotive business, welding machines are frequently employed. 

The automotive industry is massive and highly automated, therefore laser welding equipment will advance in the direction of high power and many channels.

The laser welding machine is non-contact processing, non-polluting to the product, fast, and more suitable for the production process needs of high-end consumer products for automobiles. The majority of vehicle manufacturers welcome the use of laser welding to create cars from thin aluminum alloys since it significantly decreases the weight of the body while also streamlining the manufacturing process and increasing production efficiency.

In addition, low and medium power pulse laser welding is also widely used in automotive parts, such as cylinder head gaskets, oil nozzles, and spark plugs welding.

Electrical and electronic industry

The laser welding machine specifically satisfies the processing needs of the electronics sector because laser processing is a non-contact processing technique that doesn’t result in mechanical extrusion or stress. Such as transformers, inductors, connectors, terminals, fiber optic connectors, sensors, transformers, switches, cell phone batteries, microelectronic components, integrated circuit leads, and another welding?

Due to the small heat-affected zone, fast heating concentration, and low thermal stress of laser welding, it shows unique advantages in packaging integrated circuits and semiconductor device housings.

Laser welding has also been used in the development of vacuum equipment. The thickness of the elastic thin-walled corrugated plate in sensors or temperature controllers is 0.05-0.1mm, which is difficult to solve by traditional welding methods. Tig welding is easy to weld through, plasma stability is not good, and many influencing factors exist. Laser welding has very good results. It is widely used.

Jewelry industry

Due to the high precision of laser processing, it is very suitable for precious small products in the jewelry industry. Due to the extremely fine laser-focused beam, the tiny parts of the jewelry are magnified through the microscope to achieve precision welding. The joining of jewelry chains and the setting of gemstones need to be done with a laser spot welder. A laser spot welding machine is necessary equipment.

The home building materials industry

Building materials industry

Laser marking and laser welding of high-end bathroom stainless steel items are two areas where laser welding precision has a wide range of applications. 

In addition to using lasers to mark production firm LOGOS on items like handles, faucets, stainless steel dinnerware, and knives, laser welding is also used to complete seals on high-quality electric kettles and other items.

Kitchenware industry

In the kitchenware industry, many sheet metal parts need to be welded. For example, the kitchen utensils tableware group welding and butt welding, mold production, and repair and modification in the use process. Laser welding solves the two major problems of weld seam aesthetics and welding quality.

Lighting industry

In the lighting industry, due to the complexity of the shape and structure of lighting, many hard-to-reach parts cannot be welded by ordinary welding machines, and the post-welding effect must be guaranteed. The handheld laser welding machine has exactly this function. It can adjust the welding angle as needed to improve the welding outcome and overcome the space restriction of conventional welding.

Mold and machinery manufacturing industry

The mold repair laser welding machine is the most typical example of the application of laser welding in the mold industry. Due to the obvious advantages of using non-contact processing methods, laser processing is particularly suitable for the mold and high-precision machinery manufacturing industry, such as plastic molds, rubber molds, stamping molds, casting molds, etc., due to its good fineness and low impact on materials. , forging dies, precision repair of drawing dies.

This laser welding repair technology can be used not only for repairing die wear but also for precision welding in small and precise areas, without deformation and porosity after repair.
