Why Choose Handheld Laser Welding Machine?

Handheld fiber laser welding machine is very popular in recently market. It has many advantages .Like simple structure, flexible welding, strong welding penetration. Also can weld  complex  parts.

Fiber transmission is the laser output, through the coupling system, into the optical fiber for transmission. And then through the laser output system focus on the workpiece.  Laser welding machine used for output over a long distance, thus the beam quality, intensity, energy loss and welding on the degrees of freedom is more popular. It use agile, the price is cheap, key functions and process quality is more powerful than hard light path,  fiber laser welding machine adopts new technology , laser welding head swaying realize flare, and other parameters can adjust, so you don’t need to worry about the distance. Significantly improve  welding functions and range, reduce the difficulty of welding!

In response to the limitations of the above laser welding technology, the market has gradually introduced a laser welding method with double wedge laser vibration.  There’s a special wobble vibration module on the welding head. The application of wobble welding technology can make laser welding more widely used. And it can achieve high-efficiency laser precision welding for larger or wider welds workpieces.

Handheld laser welding machine classfiy: Laser welding machine,  use for laser material processing. According to its working mode, it is divide into laser mold welding machine, automatic laser welding machine, laser spot welding machine, and optical fiber transmission laser welding.With strong expansibility, manipulator or other CNC welding machine tools can be configured in the later stage, replace the replacement of ordinary hand-held head. Swinging handheld head to meet various welding requirements. There is a tendency to replace through argon arc welding, electric welding and second protection welding.

Handheld laser welding machine application:In addition, the handheld optical fiber laser , easy maintenanc. Even without the need to maintain, as long as the daily clean. It no material loss, widely used in metal, such as sheet welding materials, solve the hutch defends the cupboard, stair lifts, shelves, oven, stainless steel doors and Windows parapet, distribution box, stainless steel household industry such as complex irregular welding process problems.

Such as in kitchen industry:This article is about the application of handheld fiber laser welding machine in Kitchen Industry.Kitchen utensils and appliances can be used in daily life, such as stainless steel pots and pans.But have you ever wondered how it was made? We know that one of the processes in the production of kitchen utensils is welding.Traditional welding method is to put the product into the fixture to achieve automatic welding, mainly using the connection between the welding wire and the workpiece to achieve welding, the workpiece after welding will often cause deformation, hardness reduction, sand holes, flowers, pinholes, wear, scratches and so on.Handheld laser welding machine has fast welding speed, good quality and high welding precision. And there will be no impact on non-operational areas during welding.

Handheld laser welding machine advantages:

Laser welding is a process that uses the radiant energy of the laser to achieve effective welding. Its working principle is: the laser active medium is excite by a specific method to reciprocate in the resonant cavity, thereby forming an excite radiation beam. When the beam and the workpiece when contacte, its energy is absorbe by the workpiece, and welding can be performe when the temperature reaches the melting point of the material. Advantages of laser welding machine:

1.Mirco welding.The laser beam can focuse to obtain a very small spot. Because it is not affected by the magnetic field and can accurately positione, it can micro-welde, which is suitable for the assembly welding of micro and small workpieces produce by large-volume automate production.

2.No loss.Because laser welding is a non-contact process, there are no problems such as tool wear and tool replacement. At the same time, it does not require the use of electrodes, so there is no concern about electrode contamination or damage, and it is easy to perform high-speed welding with automation. It can also be control by digital or computer.

5.simple operate.The laser welding machine only include the laser source,laser welding head,water chiller,operation system.There are several buttons on the machine,laser source switch,power supply switch,system switch,water chiller button.And on the system screen,some parameters here should be adjusted.For different material and thickness,the welding parameters are different.It mainly to adjust the PWM duty cycle,PWM frequency,laser power.Also need to find the correct focus on the welding head.Before shipping,we will test the machine,and save some parameters on system,when you get machine,you can weld it and learn it from the system parameters.Also we have the parameters list,when you get machine,will also reach you.

Handheld laser welding VS traditional welding machine :

Laser welding machine uses a high energy density laser beam as a heat source for efficient precision welding.

Since laser welding machine requires high precision for workpiece pre-machining, the position of the beam on the workpiece will not offset.if theassembly accuracy or beam positioning accuracy of the workpiece does not meet the requirements.

It is easy to cause welding defects, which limits the process capacity of laser welding to a certain extent. This is because the spot size is small and the weld is narrow after laser focusing.
In response to the limitations of the above laser welding technology, the market has gradually introduce a laser welding method with double wedge laser vibration, The realization method is to set a special swing vibration module on the welding head.

The application of wobble welding technology can make laser welding more widely used, and it can achieve high-efficiency laser precision welding for larger wider welds workpieces.

mirror is moved with the welding head to move relative to the workpiece to form a weld having a certain amplitude, frequency and offset.

Compared to the first two vibration welding modes, the double wedge mirror rotational vibration welding produces a spiral weld seam by the vibration module mounted between the collimating mirror and the focusing mirror, so that the focusing spot moves while the welding head moves.

When the focal length is the same, the larger the torsion angle is,the larger the vibration amplitude is.

When the torsion angle is the same, the larger the focal length, the larger the vibration amplitude.

Therefore, double wedge vibration welding allows to widen the weld joint  while achieving better weld formability.
