How to judge the welding effect of metal laser welding machine?

There are countless types of metal laser welding machines on the market. As a buyer, the most worrying thing is how to distinguish the quality of welding. So how to distinguish the welding effect of metal laser welding machine? Below is the interpretation of Jinmi Laser Editor:

Judgment of melting phenomenon during welding operation

Regarding the strength of the melting phenomenon during the welding operation, it mainly depends on the time, power density and peak power of the laser acting on the surface of the material. If the above parameters are controlled, the laser can be used to carry out various welding processes. During the welding process of the metal laser welding machine, the beam focus position is one of the most critical control process parameters. Under a certain laser power and welding speed, the maximum penetration depth and better weld shape can be obtained only when the focus is in the best range.

Metal laser welding machine

Familiar with the welding method of metal laser welding machine

There are two types of common laser welding methods, one of which is pulsed laser welding, which is currently mainly used for single-point fixed continuity and thin-piece material welding, forming circular solder joints during welding; the other is continuous laser welding Welding is mainly used for welding and cutting of large and thick parts. A continuous weld is formed during the welding operation. Generally speaking, the choice of welding materials, the choice of metal laser welding machine, and the choice of processing table are the main factors that affect the effect of laser welding.

Selection of frequency of metal laser welding machine

Generally, when using a metal laser welding machine, the frequency parameters will be adjusted as far as possible according to the customer's requirements for efficiency. Frequency has a great effect when welding efficiency is required, especially for some precision metal laser welding, when it is combined with galvanometer and scanning system, the effect of frequency will be greater. How to adjust to a suitable frequency , This will be a technical problem, but the effect of frequency will also be related to other aspects. There must be an overall effect to have a perfect welding effect.

Monitoring of tensile strength

The monitoring of tensile strength can be expanded, and the welding effect can be judged according to the inspection results. If there is poor welding or false welding of the solder joints during processing, it may not be the welding machine at this time. Maybe the material is not suitable. Change the material or change the waveform setting of the metal laser welding machine to weld again. Then start the effect evaluation.

The welding effect of the metal laser welding machine can be distinguished from many aspects. As long as we master the above points, I believe that the identification of the welding effect of the laser welding machine will not be difficult. In the operation process of using metal laser welding machine, the quality control method for metal laser welding machine also needs to be mastered. Finally, I hope that the above content will be helpful to everyone.
