Laser Welding


What is Laser welding? Laser welding is a process that typically uses a Continuous Wave (CW) laser instead of a pulsed laser (which is normally used in marking and engraving applications). The welding process exists to join two or more pieces of material together. Welding with the use of a laser is an advanced process that can be found in many different types of applications. In 1967, manufacturers successfully used the first welding system in Cambridge, England. Using this technology to join materials together creates an incredibly strong seam, making it an ideal process for industrial manufacturing. This practice is most commonly seen in the automotive industry because of its efficiency and cost-saving technology. But it is also used in the medical field, or in the manufacturing of jewelry. LMT does use a high-energy pulsed laser for the welding of thin foils for battery manufacturers and other delicate operations by use of a galvo controlled pulsed fiber laser, which is also known as “remote laser welding.”


How does Laser welding work? There are many different laser welding variations. But, generally speaking, laser welding is a process that uses a concentrated laser to impact the energy of a material. By using a targeted heat source, manufacturers can join materials together to create a strong seam. Typically, what manufacturers are attempting to do is to heat a material to bring it to its molten form. Once it becomes molten, manufacturers have to take a number of steps to prevent the material from oxidizing. Gases like argon, helium, and
nitrogen might be used for this step.

Laser welding is a process that can be used to create products like pacemakers, nuclear fuel rods, and specialized capacitor cans. Because of the high-speed output of laser welders, and the automation prospects of this technique, laser welding easily provides cost savings.


What is the Laser welding process? This welding technique requires a targeted heat source to join two materials together. During the laser welding process, a laser touches the surface of a material without penetrating it. The laser welding process can be done at high speeds. In fact, laser welding can cover meters in minutes. Laser welding is a process that you might use if a material can’t be welded with a table welder. Stainless steel, titanium, and mid steel can commonly be used in conjunction with a laser welder.
