The rise of handheld laser welder

Handheld laser welder is favored by users for its advantages such as high welding quality, fast speed, easy operation, energy saving and environmental protection. It has won a place in the market and ushered in explosive growth. Hand held laser welder can be widely used in stainless steel household, cabinet kitchen and bathroom, distribution box, shelf, stair elevator, door and window guardrail and other industries.

In 2018, handheld laser welder was gradually recognized by the market and became the annual star in the field of laser welding; In 2019, manufacturers also successively released handheld laser welder products at the Industrial Expo; By 2021, after years of technological precipitation, handheld laser welder will soon transform and usher in a high light moment.

For the production workshop engaged in small-scale processing or non large-scale welding, compared with the automatic laser welding workstation, handheld laser welder is the best choice. It does not require special equipment and welding workbench, and occupies small space. For the variety of welding products, the product shape is flexible. The handheld laser welder can fully meet the needs of this production.


Advantages of handheld laser welder

Hand held laser welder has obvious advantages in welding speed, welding quality and subsequent treatment (smooth and flat without manual grinding) of thin stainless steel plate, iron plate, aluminum plate and other metal materials.

Based on the integrated design concept, the laser, water cooling system, welding gun, wire feeder and control part are integrated together, with a smaller floor area and low site requirements. Mobile pulleys are equipped, and the work position can be adjusted at any time according to the site requirements, which is convenient and flexible.When welding thin stainless steel plate, iron plate, galvanized plate, aluminum alloy, copper alloy and other metal materials, it can perfectly replace the traditional argon arc welding and electric welding.

1) Cost saving

The cost saving advantages of handheld laser welder are mainly reflected in improving efficiency and reducing post welding treatment. Handheld laser welder is fast, 3-5 times as fast as traditional argon arc welding, and saves about 80% - 90% of electric energy than argon arc welding. One set of equipment can reduce the labor cost of more than 3 professional welders. At the same time, the welding seam is smooth, which can reduce the subsequent grinding process, and the investment return period is short.

2) High welding quality

Hand held laser welder has high welding quality, high laser power density, small welding heat affected area, no deformation, no welding scar and firm welding. The weld is smooth and uniform, and it is easy to polish or unnecessary to polish after welding. The handheld welding head is flexible and convenient, which reduces the restriction of positioning and fixture, and enables the laser welding to be operated outdoors.

3) Green environmental protection

Traditional arc welding will produce a lot of welding dust, welding slag and arc radiation, which will cause great environmental pollution. Hand held laser welder can effectively avoid these problems.

4) Unskilled and highly adaptable

The handheld laser welder is highly intelligent and easy to operate. For staff with zero welding experience, they can be trained quickly. At the same time, handheld laser welder has high adaptability and is suitable for metal welding of various specifications. Even the internal welding, splicing and external corner welding of sheet metal can be easily welded and fully welded, and the welding of any position and angle can be realized for the workpiece.

The development of metal welding technology is closely connected with the development of modern industry and science and technology, and is constantly improved with the application of metal. According to the characteristics of the process, it can be divided into three categories: fusion welding, pressure welding and brazing. Among them, fusion welding can be divided into argon arc welding, submerged arc welding, CO2 gas shielded welding (two guarantee welding), laser welding, etc; Pressure welding is divided into resistance welding, cold pressure welding, forging welding, etc; Brazing is divided into flame brazing and induction brazing.

Application and development of laser welding

The application forms of laser welding include single laser welding, laser wire filling welding, swing laser welding, handheld laser welding, laser TIG / MIG / MAG composite welding and blue light infrared laser composite welding. In 1985, German Thyssen Steel Co., Ltd. and German Volkswagen Co., Ltd. successfully adopted the world's first laser tailor welded plate on the Audi 100 body.

In 2002, China's first tailor - welded blanks production line was officially put into operation.
In 2003, AVIC 625 Institute applied the "double beam laser welding" technology to the aircraft manufacturing - the key structural parts of aviation ribbed wall panels.

From 2008 to 2010, China successively issued national standards for laser welding and machinery industry standards: GB / T 19867.4-2008 laser welding process specification and JB / T 11063-2010 laser welding process guide. Since 2015, the Chinese government has vigorously promoted the development of new energy vehicles, mainly electric vehicles. Power batteries bring a lot of demands for laser processing. Laser welding technology is adopted for connecting pieces, cells, copper materials, aluminum alloys and battery packages, which greatly promotes the development of laser welding automation.

In 2018, thanks to the progress of laser technology and the decline of laser prices, domestic fiber lasers were widely used, and handheld laser welder came into being.
