How thick can the laser welding machine be welded?
1. The 1000 watt laser welding machine can weld stainless steel within 3 mm.
2. The 1500 watt laser welding machine can weld stainless steel within 5 mm.
3. The 2000 watt laser welding machine can weld stainless steel within 8 mm.
If the weld is larger than 0.3 mm, it is recommended to use a laser welding machine with wire feed. The material thickness is less than 1 mm, it is recommended to use non-wire laser welding, because the wire-feeding welding speed is slower than the non-wire-feeding, and it is easy to cause deformation.
Extended information
advantage：
(1) The required amount of heat input can be reduced to the minimum, the change range of the heat-affected zone is small, and the deformation caused by heat conduction is also the lowest.
(2) The welding process parameters of 32mm plate thickness single pass welding have passed the verification, which can reduce the time required for thick plate welding and even save the use of filler metal.
(3) There is no need to use electrodes, and there is no concern about electrode contamination or damage. And because it is not a contact welding process, the wear and deformation of the machine tool can be minimized.
(4) The laser beam is easy to focus, align and be guided by optical instruments. It can be placed at an appropriate distance from the workpiece, and it can be re-guided between tools or obstacles around the workpiece. Other welding methods cannot be used due to the above-mentioned space constraints.
