Laser welding is the use of high energy laser beam as a heat source, through the control of laser pulse width, energy, peak power and repetition frequency and other parameters, so that the workpiece melting, forming a specific molten pool.

Advantages of laser welding:

1. Suitable for small and micro metal workpiece precision welding, fine welding;

2. Compared with other welding processes, laser welding has a small thermal deformation range on the workpiece surface;

3. Can be used for metal sheet welding, and laser welding efficiency is relatively high, the industry is widely used;

Disadvantages:

1. High requirements for welds, generally no more than 0.1-0.3MM welds, more than 0.1MM workpiece welding, generally use swing welding head;

2. The current laser equipment is large, not easy to carry, not suitable for outdoor work;

3. Compared with traditional welding equipment such as argon arc welding, the one-time investment is higher;

Shenzhen Xinde laser welding equipment welding finished product surface welding spot smooth, flat without bubbles; The welding material deformation is small, the heat affected zone is small and the processing is pollution-free.

Laser welding can be divided into two kinds, continuous laser welding and pulsed laser welding, what is the difference between the two?

Most continuous laser welding is a high power laser, the power is generally more than 500 watts, like more than 1mm plate is generally used this laser. Its welding principle is based on the deep fusion welding of the keyhole effect, the depth to width ratio is large, can reach more than 5:1, the welding speed is fast, the thermal deformation is small. The output power of continuous laser is generally relatively low, suitable for the requirement of laser continuous work, in machinery, automobiles, ships and other industries are widely used.

Pulsed laser welding is mainly used in spot welding and seam welding of thin-walled metal materials within 1mm thickness. The surface of the workpiece is heated by laser radiation, and then diffused to the interior of the material through heat conduction. The biggest advantage of pulsed laser welding is that the workpiece temperature rise is small, the heat affected zone is small, the welder material deformation is small. Pulsed laser has a large output power, widely used in lithium batteries, electronic components, power batteries and other industries.
