Laser Applications in Sheet Metal Processing – Welding and Cutting

Laser Welding, Short Set-up Time, and Flexibility

Compared to other thermal joints, the low heat input is a major advantage for pulsed laser welding when processing sheet metal. This reduces distortion and thus the effort required for subsequent straightening. Visible seams benefit from the excellent appearance of the welding seam. Elaborate re-work – especially with stainless steel – is no longer necessary

Another plus: thin wall thicknesses can be welded thanks to the low heat input. Various sheet thicknesses can also be combined. Furthermore, lasers provide new options in component design.

Gap dimensions up to 0.5 mm can be bridged without welding filler. Production is increasingly subject to component variety or variance. With systems from ALPHA LASER, production can practically start immediately. There is no need for programming and costly jig constructions. This means even individual parts or small series can be realized quickly and inexpensively.

Using the fiber laser for welding in CW mode (continuous wave) enables deep welding (3-4 mm) of solid components in mechanical engineering, for example.

Your benefits at a glance:

  • High welding seam quality, which means cumbersome re-work is no longer required
  • High welding speed saves time
  • Low thermal impact during pulsed welding and thus hardly any distortion
  • Deep welding with fiber laser
  • Low quantities or prototypes can be realized cost-effectively
  • High dimensional stability
Advantages

Laser cutting is viable even with small lot sizes, provides high-quality results, and there are no tooling costs.

Almost all metallic materials can be cut with a laser cutting system. The cut gaps are small, smooth, and clean, so that re-work is
often not required. Low quantities or prototypes can be quickly and cost-efficiently realized with our AC laser cutting system.
There is little to no distortion, as little heat is introduced into the sheet.
