Laser keyhole welding vs. resistance spot welding

Most manufacturers are looking for ways to save money and improve efficiency without negatively impacting quality. Manufacturing operations that are using resistance spot welding can reap significant productivity and quality benefits in some applications by converting to laser keyhole welding.

Implementing laser keyhole welding can result in a welding process that is three to four times faster compared to resistance spot welding — for improved productivity and efficiency — while also increasing weld quality and repeatability. However, laser keyhole welding may not be the right fit for every job.

There are several factors to keep in mind when considering if laser keyhole welding is the best choice for your welding application.
