What are the main types of laser welding machines

  1. Pulsed laser welding: The pulsed laser welding method of laser welding machine is mainly used for single point fixed continuous and thin material welding, welding to form a circular welding joint.
  2. Plasma arc welding: This laser welding machine welding method is similar to argon arc, but its torch will produce a compressed arc to increase the arc temperature and energy density, it is faster than argon arc welding, depth of melt, but slightly inferior to laser welding.
  3. Continuous laser welding: This welding method is mainly used for welding and cutting of large thick parts, and a continuous weld is formed during the welding process. In general, the choice of welding material, the choice of laser welding machine brand, and the choice of processing table are the main factors affecting the effect of laser welding.
  4. Electron beam welding: It relies on a beam of accelerated high-energy density electron stream hitting the workpiece, generating huge heat in a small dense area on the surface of the workpiece, forming a small hole effect and thus implementing deep fusion welding. The main disadvantage of electron beam welding is the need for a high vacuum environment to prevent electron scattering, complex equipment, the size and shape of the welded part is limited by the vacuum chamber, the age of the welded part assembly quality requirements are strict, non-vacuum electron beam welding can also be implemented, but due to electron scattering and poor focus affects the results.

How to choose laser type for laser welding machine

Industrial laser welders can be equipped with one of two lasers: a pulsed laser or a continuous laser. Which one you choose depends on the thickness of the material you are welding.

The pulsed laser acts on thin and light metals, preventing them from deforming or melting. This type of laser welder is mainly used for welding sheet metal, razor blades, gold jewelry links and other materials.

Continuous laser is mainly used to weld thick metal parts and is particularly effective on refractory metals. If this type of laser welding machine is used on parts that are too thin, the parts may be damaged.

There are many aspects involved in the configuration of industrial laser welding machines, and the configuration of laser welding machines is different for different purposes. For example, mold welding for welding molds, jewelry welding for welding jewelry, fiber optic transmission laser welding machine, etc. The price naturally varies from equipment to equipment. China laser welding machine manufacturers reminded in the purchase of metal laser welding machine, should be based on their product type, processing technology and processing requirements to choose the right machine.
