Fiber Laser Welding: Advantages, Systems and Applications
By Stéphane Melançon on May 05, 2023

Fiber laser welding is a welding process that uses a laser beam as the heat source. As non-contact tools, fiber lasers are low maintenance and offer fast welding speeds.

How Laser Weld Monitoring Systems Work
By Stéphane Melançon on April 07, 2023

Laser welding needs to be controlled to detect bad welds and ensure quality. Ensuring good weld quality is getting more challenging, as laser welding is increasingly used for micro welding applications that demand more precision, like battery tab welding in the automotive industry. 

Electric Motor Manufacturing - 7 Ways the Industry is Changing
By Stéphane Melançon on April 07, 2023

We often think of the electrification of the industry as a movement away from fossil fuels to reduce global emissions. But there are other, less obvious implications that are affecting electric motor manufacturers and consumers.

What is a Hairpin Motor - Benefits & Assembly Process
By Stéphane Melançon on February 23, 2023

The advantages brought by hairpin motors are making electric vehicles more competitive not only with previous generations of EVs, but also with combustion engines. They are more efficient, have a higher power density and thermal performance, and are simpler to manufacture.

Laser Spot Welding & Laser Seam Welding in 2023
By Stéphane Melançon on February 14, 2023

Laser spot welding is a welding process that uses the power of a laser beam to join two metal surfaces at a single spot. Laser seam welding is when surfaces are welded over a long, continuous surface.
