To better weld metal materials, it is necessary to choose such a fiber laser welding machine!

2019-10-29

Every merchant hopes to improve the production quality of their products to gain market recognition and sales share. However, for processed products like metal welding, it is indeed difficult to solve the welding defects in production without suitable laser welding machines. Since there are many types of laser welding machines, not all laser welding equipment can weld the same type of material, so we must choose the appropriate welding equipment to better complete our welding tasks.
What types of laser welding machines are there?
1. YNG Laser Welding Machine:
Represented by hard optical path welding machines, used for pulse welding, which is commonly used for spot welding processing. It requires optical path design and involves many optical lenses, including full reflection, half reflection, beam expansion lenses, collection lenses, 40-degree lenses, parallel lenses, focusing lenses, and protective lenses. At the same time, the laser pump also requires a laser cavity, which includes xenon lamps, YNG crystal rods, metal/ceramic cavities, red light emitters, etc. The debugging is complex, and maintenance is relatively cumbersome, but the purchase cost is low. Those with some technical knowledge can maintain, install, or replace parts themselves. This type of equipment is suitable for mold spot welding repair. To achieve continuous welding, it can only be done through overlapping spot welding (as we all know, a line is composed of points, which is the principle).
2. Fiber Transmission Laser Welding Machine:
The principle is the same as above, but the laser output is transmitted to the welding head via fiber optics. The purpose of using fiber transmission is to avoid limitations in welding processing range and to improve the operational freedom of automated mechanisms. At the same time, using fiber transmission can further improve the quality of the laser beam, so its application in industrial welding production is also feasible. However, the maintenance process still requires the same configuration and maintenance as above, and an additional set of fiber couplers is needed to couple the laser into the fiber for transmission.
3. Pure Fiber Laser Welding Machine:
The pure fiber laser welding machine has many characteristics due to the use of pure laser types. If classified by different properties, it can be divided into various types. For example, based on the diameter of the fiber, there are single-mode and multi-mode lasers, as well as MOPA lasers, semiconductor lasers, QCW/CW lasers, green lasers, etc. For different purposes, please choose the appropriate product. For instance, if you are using a single-mode laser for deep fusion welding, its effect will not be as good as that of a multi-mode type. If you want to mark and achieve blackening of aluminum, then using a MOPA laser is an ideal choice. If you want to achieve continuous welding and spot welding, then a QCW laser can help you achieve that. Continuous welding can also be done using a CW laser. Semiconductor lasers are more used for precise small-scale welding in electronics because they do not generate heat during welding, essentially termed cold processing welding, and can be applied to precise welding of PCB circuit boards.
Therefore, when welding different products, it is necessary to choose according to the actual materials of the users, and it is not enough to just have one laser welding machine to weld all materials. Even if it can be welded, the appearance process and firmness cannot achieve the ideal effect.
Fiber laser welding machines are currently the most widely used equipment in laser welding and are also products that users trust. They have a wide range of applications, good beam quality, and are suitable for automation matching. Therefore, as long as the budget allows, fiber laser welding machines (pure fiber) are your ideal choice. You may ask me about the price of fiber laser welding machines. We can tell you that the prices of the above three types range from low to high, and the order of market introduction from earliest to latest is YAG laser welding machine -> fiber transmission laser welding machine -> pure fiber laser welding machine, with prices starting from 40,000 and no upper limit!
So if your product still cannot be welded well, please do not complain. You need to check whether your welding machine is suitable for your product materials. Due to the rapid technological updates, new laser equipment that may better meet your needs may appear later, so upgrading is also something users need to pay attention to!
