Laser welding in sheet metal processing 

 

ALPHA LASER offers flexible lasers for welding and cutting sheet metal

Our laser welding devices and laser cutting machines yield outstanding seams and smooth cutting edges when processing sheet metal. Sheet metal manufacturing generally deals with items that must be produced quickly and cost-efficiently while still providing high quality. 

Manufacturing techniques using lasers for sheet metal processing allow you to produce economically even at batch size 1, without material distortion or tedious rework on workpieces. We make laser systems for sheet metal processing that enable you to precisely, quickly, cost-efficiently, and above all flexibly complete the job.

 

Shorter setup times for laser sheet metal processing

Compared to other thermal joining methods, one of the major advantages of pulsed laser welding for sheet metal processing is the low heat input. This minimizes distortion and no subsequent straightening is required. The visible seams look outstanding. Tedious rework – particularly with stainless steel – is not required with laser welding.

The low heat input of our laser machines allows you to weld very thin panels. Even different sheet thicknesses can be effortlessly fused.  Gap dimensions up to 0.5 mm can be bridged without welding filler.

 We offer laser devices for sheet metal processing matched to your production environment – from painstaking welding jobs through to high-precision laser cutting. The closed ALV laser system is used for the stationary laser welding of small parts, micro welding, and many other applications of sheet metal processing with lasers. Very large sheet metal workpieces are welded with the ALW, which is a laser-safe workplace that doesn't require any additional safety measures in the production environment. Another alternative is the open and mobile laser welding device ALFlak.

 

Advantages of laser sheet metal processing with laser machines from ALPHA LASER

  • High welding seam quality, which means no tedious rework is required
  • Less time needed thanks to high welding and cutting speed
  • Almost no material distortion thanks to minimal thermal impact
  • Deep welding with fiber laser possible
  • Cost-effective production of small batches or prototypes
  • High dimensional stability
Advantages

Our laser sheet metal processing customers are not the only ones using high-quality laser technology and high-performance laser systems: companies in the fields of tool and mold manufacture, mold repair, precision engineering and many other industries do too.

 

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

Our laser cutting systems use fiber lasers for precision-cutting of sheet metal.

Do you frequently manufacture prototypes or single pieces? The compact AC 300 F / AC 450 F cutting laser can easily and quickly cut through metal sheets up to 3 millimeters thick, without tooling costs. The closed class-1 laser system for laser cutting applies CAD cutting paths at lightning speed and produces even complex sheet metal workpieces in record time. The cut gaps are small, smooth, and clean, so that no rework is generally required. Thanks to the pinpoint heat input, only little heat is introduced into the material, which minimizes distortion or eliminates it entirely. 

 The laser workstation AL-SWS facilitates round cutting of sheet metal tubes and can handle specific sensor manufacturing tasks, which is another sector that uses laser sheet metal processing.
