Laser beam welding is performed with special equipment. Such a method allows producing items with a high quality joint at high speed.
Welding occurs due to heating and melting of the processed metal. A laser beam that penetrates the metal causes these processes. The equipment creates a light flux with uniform wavelength. A focus is achieved by guide mirrors. The energy flow is controlled by focus lenses.
The laser welding process is performed in the following order:
The laser beam has a small cross-section. This allows you to fill the smallest cavities and unevenness of the material and ensures the most even and smooth joint seam. This advantage is unique to laser beam welding. Also, due to the high speed of laser beam travelling, there is not enough time for metal to oxidize.
With the laser beam welding, it possible to get two types of connecting seams:
Features of welding different materials.
Each metal has its own set of characteristics that should be taken into account when welding with the laser beam welding machine. Note: before laser beam welding, it is recommended to pre-clean the material. This is especially true for those metals that are prone to corrosion. The cleaning can be done with a usual stainless brush.
Titanium
To weld parts from titanium, it is recommended to pre-clean the material. For example, by sandblasting. Then, it is advisable to etch, wash, and treat the metal with helium.
Aluminum
The metal is prone to oxidation and releasing volatile elements. That is why, it is recommended to etch it and treat it with a hand scraper.
Galvanized steel
Such a metal type as well as brass and other zinc-containing alloys should not be welded with a handheld laser machine. This is due to the release of hazardous volatiles. Such treatment is possible, but a very powerful exhaust system is required.
Wattsan laser weld machine overview
The equipment is designed for manual laser welding. Using it, you can process the following metals:
The machine is supplied in four versions with different power of the laser source (500W, 1000W, 1500W, and 2000W). You can choose the emitter brand from the following: Reci (is included in the basic version of the machine), Raycus, IPG, JPT.
The equipment dimensions are 1120x550x1120 mm. It is equipped with a 2-motor welding head and program control system. This allows you to set up the type and thickness of a weld seam.
The Wattsan laser weld guarantees high quality and durability of welding due to the absence of material deformation during processing. Mechanical post-treatment is not required. Thus, the machine saves up your time.
It is easy to operate and accessible to people without specialized training. To start working, you just need to fix two metal objects in several places. After that, you can start welding.
Our customers choose the Wattsan laser weld to produce:
In addition, it can be used in automotive and aircraft industries.
