Laser welding machine as a new type of welding equipment, due to the excellent welding effect, a wide range of applications, once the introduction of the processing industry to gain favor. However, due to the countless manufacturers of Fiber laser welding machines on the market, as the first time buyers of laser welding machines are most worried about the quality of laser welding machines, how to identify the quality of welding, is the most concerned about many friends. Next, follow GOLD MARK laser to understand how to identify the laser welding machine in the metal welding effect is good or bad.

1.familiar with the laser welding machine welding method

There are two types of common laser welding methods, one of them is the pulse laser welding, currently mainly used for single-point fixed continuity and book material welding, welding the formation of a circular welding point; the other for the continuity of laser welding, mainly used for large thick pieces of welding and cutting, welding operation process to form a continuous weld. 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 effectiveness of laser welding.

2. Judgment of the melting phenomenon during the welding operation

For the welding operation process melting phenomenon produced by the degree of strength, mainly depends on the laser action of the material surface time, power density and peak power, control the above parameters can use the laser to start a variety of different welding processes. Metal laser welding machine in the welding process, the beam focus position is one of the most critical control process parameters, in a certain laser power and welding speed, only focus in the best range to obtain the maximum depth of melt and better weld shape.

3. laser welding machine in the welding metal frequency selection

Generally when using metal laser welding machine, will try to adjust the frequency parameters according to the requirements of the customer for the efficiency of the above. Frequency in the welding efficiency requirements, there is a great role, especially for some precision metal laser welding above, will cooperate with the mirror plus scanning system, the role of frequency will be greater, how to adjust to the appropriate frequency, which will be a technical problem, but the role of frequency will also be related to other aspects, there must be the overall effect in order to have the perfect welding effect.

4.Tensile strength monitoring

We are able to monitor the tensile strength and judge the welding effect based on the results of the inspection. If there is a bad weld or a false weld during the process, it may not always be the welding machine, but the material may be inappropriate.

Through the above 4 points, I believe that we have a preliminary understanding of the effect of laser welding machine welding metal identification, in the use of laser welding machine operation process, for the metal welding quality control methods, is required to slowly master, I hope the above content will help you.
