There are countless types of metal laser welding machines on the market, and the most worrying thing for a purchaser is how to identify the quality of welding. So how do you need to identify the welding effect of metal laser welding machine? The following is a small edition of Jinmi Laser for everyone to interpret:

Judgment of melting phenomenon during welding operation

In view of the strength of the melting phenomenon in the welding operation process, mainly depends on the time, power density and peak power of the laser on the surface of the material, and the above parameters can be controlled to use the laser to carry out a variety of different welding processes. In the welding process of metal laser welding machine, the beam focusing position is one of the most critical control process parameters, under a certain laser power and welding speed, only the focus is in the best range to obtain the maximum penetration depth and better weld shape.

Metal laser welding machine

Familiar with the welding mode of metal laser welding machine

There are two types of common laser welding methods, one of which is pulsed laser welding, currently mainly used for single point fixed continuity and book material welding, welding to form a circular welding spot; The other is continuous laser welding, which is mainly used for welding and cutting of large and thick parts, and a continuous weld is formed during the welding operation. In general, the choice of welding materials, the choice of metal laser welding machine, the choice of processing table, is the main factor affecting the effect of laser welding.

Frequency selection of metal laser welding machine

In general, when using metal laser welding machines, the frequency parameters will be adjusted as far as possible according to the requirements of customers for efficiency. Frequency has a great role in the requirements of welding efficiency, especially for some precision metal laser welding, will cooperate with the galvanometer and scanning system, the role of frequency will be greater, how to adjust to the appropriate frequency, this will be a technical problem, but the role 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 tensile strength can be monitored, and the welding effect can be judged according to the results of the inspection. If there is poor welding during processing, welding spot welding, etc., this time is not necessarily the welding machine, perhaps the material is not suitable, in the replacement of materials or change the setting of the metal laser welding machine waveform welding again, and then the effect evaluation.

The welding effect of the metal laser welding machine can be identified according to 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 control method for the quality of metal laser welding machine is also needed to master, and finally, I hope the above content will be helpful to you.
