Application area with laser welding 
The highest welding efficiency is observed for products with a thickness of up to 10 mm . The method is not widely used for economic reasons, since the cost of installation and additional equipment is at a high level.

Such processing is used in cases where other types of welding cannot be applied and an accurate preservation of the part structure is required after all manipulations. The concentrated impact of the energy beam guarantees minimal changes in the properties and geometry of the product. This is an excellent solution for joining difficult-to-weld metals, without the need for additives, vacuum chambers and other additional elements.

Process conditions and methods
To achieve high beam power, focusing is necessary. It is performed in a series of successive reflections from the front and rear hemispherical mirrors. When the beam intensity exceeds the threshold value, it passes through the center of the front mirror and then, through a system of guide prisms, to the working area.

Laser welding of metals can be carried out with different interposition of the joined workpieces. The depth of metal penetration in the working area can be adjusted in a wide range - from surface to through. Work can also be carried out with a continuous beam or intermittent pulses.
