Simply put, laser welding uses a laser beam to melt and solidify a material joint instantly with the powerful heat generated by the laser beam to achieve the purpose of welding. The entire welding process takes only a few seconds. You can use the welding machine for electricity, seam, lap, butt jointing, and other processes. Laser welding is used in many industries and is an efficient operation to achieve high quality spot welding.
The advantages of laser welding over conventional welding techniques are very obvious. Here are some of their benefits:
The high degree of automation
Exact welding positions, suitable for industries that require high welding precision
It saves labor and time
Less wasteful consumption of welding material
There are no obvious disadvantages to using a handheld laser welding machine. The most significant burden may be the high purchase cost, which is not easy for partners with an insufficient budget to buy a machine. And the machine also requires a certain amount of money for maintenance in the later stages of use. Secondly, purchasing the old version of the handheld laser welding machine requires a high level of skill for the operator.
Before the s, most of the lasers used at this time were ruby-pulsed lasers. These pulses and powers were relatively low so they could have used them more effectively. Later higher, power lasers appeared and became the primary choice for spot and seam welding of metallic materials.
At the end of the 20th century, more competent and efficient gas-shielded welding gradually appeared. This was when manual arc welding began to be phased out.
In the s, more advanced welding machines, such as computer-aided design and machine automation, emerged. This was when our welding machines were primed. In the 30 years from the s to , machines developed very rapidly. Welding machines gradually diversified and became mainstream equipment in various industries.
Welding technology is used in many industries, and to do the job faster and better, we need to choose some equipment to assist the operation. This is the main reason why welding machines are still being innovated.
Choosing a welding machine can save time to a great extent and increase efficiency. The most important thing is that it can greatly benefit the factory. Good welding results give your products a good competitive edge in the industry.
All usage parameter settings are clearly stated in your user manual. So we will cover only a few common parameters.
The handheld metal laser welding machine mainly reflects the laser light through the lens, and the metal absorbs the laser light to reach the melting point and then melts. After cooling, the materials are tightly bonded to each other.
Handheld laser welders can be classified according to their laser heads and lasers.
This is a common way of classifying our welding machines. Most people think of fiber, CO2, and Nd: YAG first, all of which have advantages and are suitable for different welding fields.
Regardless of how it is classified, you must first define the type of welder suitable for you before you buy it. This will be very beneficial for your business to proceed.
Take geweike's handheld laser welder as an example. Its composition mainly includes three major parts: laser welding head, laser source, and water chiller. Their respective functions are as follows.

This is one of the most important characteristics that affect laser processing. The high power density allows the material to heat up and melt instantly, making the metal welding process faster.
The pulse waveform is a key consideration in welding, especially plate welding. This pulse waveform directly affects the temperature of the metal surface. Some of the energy on the surface of the metal is lost at the peak of the pulse.
Pulse width is a basic indicator to clarify material wastage in welding. It can have a direct impact on your production costs.
When the focal plane is below a workpiece, negative defocusing is possible. Higher penetration is possible. The power density distribution is uniform across all planes except the one near the laser focal point.
Geometric optics theory states that the power density of the corresponding planes will be approximately equal if the positive and the negative defocusing planes are located at the same distance from the welding plane. In practice, however, the form of the melt pool can be quite different.
We can see from the increasing sales of handheld metal laser welding machines every year that its advantages are very obvious. It is used in the military, aviation, decoration, and many other industries.
Handheld laser welding has made the manufacture of many metal parts easier. The following is a brief list of applications for welding machines in various industries:
Laser welding is involved in manufacturing 15% of the automotive industry. This is especially true for the manufacture of automotive chassis and bodies. This is one of the industries where the number of handheld laser welders for sale is relatively large.
We often see mini handheld laser welders in jewelry stores, mainly used to repair broken bracelets or other jewelry. And almost all jewelry production uses handheld fiber laser welding machines for production.
As medical aid, we see handheld laser welders in a very small part of the hospital. Although their presence is small, they are essential for many medical tasks.
Can solder many electronic components and circuits of circuit boards without welding machines. The manufacturing and repair of cell phones, computers, and smart appliances all use soldering machines.
You may encounter unsatisfactory welding results without operating experience or first use after replacing a new machine. Many factors affect the laser welding effect. Besides setting parameters, you know other reasons?
This is an important factor that affects the welding effect. If you buy a machine unsuitable for welding this material, even if the perfect parameters are set, it will not produce the desired effect. At the same time, metal in the welding process is some laser reflection. If the welding effect is not satisfactory, we can apply a layer of graphite to the surface of the metal material.
If the welding seam is too big or cannot align the light spot and the welding seam, it will lead to poor welding effects. So the chuck needs to be carefully tightened before welding to achieve the best result.
