New development trend of hand-held laser welding machine

With the development of laser technology, laser welding technology has matured, and even 3D laser welding and metal laser welding have a higher level of technology. Laser technology is another major invention at present. The emergence of laser welding machine has given the current welding technology a qualitative leap, allowing the metal and non-metal materials of different materials to be easily connected, allowing us to get rid of some traditional processing problems.

Laser welding advantages

Hand-held laser welding is fast, 2-10 times faster than traditional welding, and a machine can save at least 2 welders per year. After welding, the weld seam is smooth and beautiful, reducing the subsequent grinding process, saving time and cost. Laser welding workpiece has no deformation, no welding scar, and welding is firm. Laser welding has few consumables and long life.

New Technology of Filled Wire Laser Welding Technology

Laser wire filler welding is a method of using the same or similar filler metal as the base material to melt the base material and the solder to condense to form a weld. Laser welding generally does not fill the welding wire but requires high gaps in the assembly of the weldment, which is sometimes difficult to guarantee in actual production, limiting its scope of application. The use of wire-filled laser welding can greatly reduce the requirements for assembly gaps. For example, if the thickness of the aluminium alloy plate is 2mm, if the filler wire is not used, the plate gap must be zero to obtain a good shape. If a φ1.6mm welding wire is used as the filler metal, even if the gap is increased to 1.0mm, a good weld can be formed. In addition, the filler wire can also adjust the chemical composition or perform multi-layer welding of thick plates.

Development status of laser welding

As a direction of laser application, laser welding is a combination of current technology and traditional technology, but it has different characteristics from traditional processing. Due to its high power density and fast energy release, laser welding is more efficient than traditional methods in terms of processing efficiency. At the same time, the spot is small after the laser focusing, which also makes the bonding between the two materials better during the welding process, without causing damage and deformation of the material surface. Therefore, after the completion of welding, there is no need to do post-processing on the weld.

In the field of metal welding, aluminium alloy welding accounts for a large proportion, because aluminium alloy has a high specific strength, high fatigue strength, good fracture toughness and low crack growth rate, and also has excellent forming processability and good corrosion resistance. Aluminium alloys have been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries. The wide application of aluminium alloy has promoted the development of aluminium alloy welding technology, and the development of welding technology has promoted the research of laser welding technology. At the same time, the development of welding technology has expanded the application field of aluminium alloy.
