Applications and Advantages of Laser Welding Machine

Welding is the process of permanently joining two or more metal parts, by melting both materials. The molten materials quickly cool, and the two metals are permanently bonded.

Method of laser welding machine sheet metal protected by using low-vaporizing-temperature materials, whereby, before being subjected to a laser welding beam along a weld area, two metal sheets are placed on top of each other in such a manner that at least one layer of the said protecting material is located between the sheets at the weld area and that the weld area communicates directly externally of the weld area between the sheets whereby gases generated by vaporization of said protective material may escape from the weld area.

Low carbon steel is most suitable for spot welding. Higher carbon content or alloy steels tend to form hard welds that are brittle and could crack. This tendency can be reduced by tempering.

Austenitic Stainless steels in the 300 series can be spot welded as also the Ferritic stainless steels. Martensitic stainless steels are not suitable since they are very hard.

Aluminums can be welded using high power and very clean oxide free surfaces. Cleaning the surface to be oxide-free, adds extra costs (that can be avoided with low carbon steel).
Dissimilar materials cannot be spot welded due to different melt properties and thermal conductivities. Plated steel welding takes on the characteristics of the coating. Nickel and chrome plated steels are relatively easy to spot weld, whereas aluminum, tin and zinc need special preparation inherent to the coating metals.


  • Friendly and ergonomical man-machine interface.
  • Reliable performance and low maintenance.
  • Auto cooling.
  • Easily controlled welding parameters (e.g., current, pulse width, frequency) and programmable welding path.
  • Optional various worktable sizes.
