Selection principle and method of laser welding machine The efficiency of laser welding machine is 2-10 times faster than traditional welding, and the processing cost is reduced by about 30% compared with traditional Arc welding. The operation is simple, and after simple training, good results can be achieved. The welding points are uniform, the penetration is good, the weld seam is flat, and there are no pores. It can achieve 360 degree welding at any angle.
Therefore, laser welding machines are becoming more and more popular in the industrial market, and more and more industries are using them. For laser welding machines, different configurations have different effects. So how to choose a suitable laser welding machine is one of the basic knowledge that our technologists must have.
1. First, confirm whether the product is suitable for laser welding
When selecting a laser welding machine, first you need to confirm whether your product is suitable for laser welding technology. On the one hand, we need to understand the scope of Laser beam welding, and at the same time, we can let laser welding machine manufacturers provide proofing services and support. By telling the supplier to weld the product materials and letting the manufacturer weld the samples, we can confirm whether the laser welding machine can meet our own requirements.
In addition, the gap between product pairs is also a very important factor in selecting welding machines. Laser beam welding is a kind of precision welding, which includes two aspects. One is that the effect of welding precision products is good, and the other is that the requirements for welding products are high, and it is best to have no gaps, because Laser beam welding is achieved by self fusing samples.
If the gap between the welds exceeds 0.25mm, it is generally necessary to add welding wires, and manual welding machines can only be selected.
When the weld gap is less than 0.15mm, automation can be basically realized, and automatic laser welding machine is adopted.
2. Select appropriate laser welding machine power
The laser generator is the core of laser equipment. The types of welding machines are roughly divided into 500W, 1000W, 1500W, and 2000W. Currently, the most commonly used types on the market are 1000W and 1500W, which are basically capable of daily welding work.
Of course, the higher the power of the laser, the higher the price, because the higher the power, the higher the requirements for the equipped laser rod and cooling system.
Generally, the deeper the welding depth is required, the greater the power of the corresponding laser welding machine. The higher the price. For example, if the welding depth is required to be 0.5mm-3mm, penetration welding or spot welding, then a 1000W laser welding machine can meet the demand. However, if it is continuous welding, it is better to use a higher power laser, and it is appropriate to choose a 1500W or 2000W laser welding machine.
3. Consider the price and configuration of laser welding machine
The laser welding machine is also divided into high configuration and low configuration. The price of different laser equipment is different. High end welding equipment can make the processing effect more comprehensive and the welding effect better, but the price is also relatively expensive. If there is not a high requirement for processing efficiency, it is recommended to choose the one with average performance and choose according to the actual situation.
Some companies are loyal to foreign brands, and the prices will naturally be higher. The price of domestic laser welding machines will be relatively low. At the same time, domestic laser technology has reached international standards, and after-sales problems will be handled more timely and conveniently, so it will be more secure.
In a word, we can choose according to our budget and hobbies. When choosing a laser welding machine, on the one hand, we should consider whether our products are suitable for welding with a laser welding machine, and on the other hand, we should consider the power requirements according to the depth of the laser welding machine. The laser welding machine can not be selected blindly, and can not blindly pursue high-end or low price. The most suitable one is the one that suits you.
