Laser welding
SSP239_051
Laser welding offers the following
advantages:
- high productivity
- high rigidity
- weight savings
(through smaller overlap)
- access only required from one side
- very little distortion as a result of the low
heat impact in the process
- simple, clean seam design
- no surface pre-treatment required
The process of laser welding is used to weld
sheet metal/extruded profiles and cast parts.
In the A2 the following welds are achieved
with a lap seam:
- sheet metal to sheet metal
- sheet metal to cast parts
- cast parts to extruded profiles
In this way it is possible to replace the
bonding techniques of spot welding, riveting
and MIG welding.
