Laser welding of metal

The company LLC Production Complex «Svet Shakhtyora» offers laser welding services to create permanent connections of various metals

Laser welding allows for permanent joining of materials with a thickness of 0.1-10 mm. The metal being processed is melted through or partially, the spatial position can be any.

Technical features and capabilities of the technology

• Possibility of joining different metals. These are stainless steel, titanium, silver, brass, copper, aluminum, cast iron and other chemical elements and alloys. It is also possible to weld glass and plastics with a laser.
• Versatility. The laser can weld both small parts and large workpieces.
• No need to create special conditions. The laser works in a normal environment, without the need for a vacuum or intense heating.
• The thermal effect is local and short-term. The crystal lattice of metals is not damaged, deformations do not occur, the structure of materials is preserved, and strength is not lost.
• Possibility of joining dissimilar materials. It is possible to fix even metals with different chemical and physical properties.
• The seams are thin, clean, neat, fully welded, and durable. During the process, there are no splashes, scale, or bubbles in the molten metal. The structures serve for a long time and demonstrate high strength..

If necessary, double-sided welding is possible. Also, depending on technological requirements and other features, laser welding can be divided into types:

• with through penetration - mainly for sheet structures
• without through-fusion - mainly for thin parts or sealing

When welding, oxidation protection is most often done for the seam. This protection ensures better penetration and reliability of the welded structure. Laser welding allows you to weld the material in hard-to-reach places, which leads to a decrease in the number of defects in welded products.
