The 1000 Watt laser welding machine can weld stainless steel up to 3 mm.
The 1500 Watt laser welding machine can weld stainless steel up to 5mm.
The 2000 Watt laser welding machine can weld stainless steel up to 8 mm.
For welds greater than 0.3mm it is recommended to use a laser welding machine with wire feed. Material thickness less than 1 mm, it is recommended to use the laser welding without wire feed, because the wire feed welding speed is relatively slow without wire feed, which can easily cause deformation.
Advantages of handheld laser welding machines.
1. The amount of heat input can be reduced to the minimum required, the heat affected zone has a small range of metallurgical changes and the deformation caused by heat transfer is also minimal.
2. 32mm plate thickness single pass welding process parameters have been checked and qualified, which can reduce the time required for thick plate welding and even eliminate the use of filler metal.
3. No electrodes are required, so there is no concern about contamination or damage to the electrodes. And because it is not a contact welding process, the wear and tear on the machine and deformation can be minimised.
4. The laser beam is easily focused, aligned and guided by optical instruments, and can be placed at an appropriate distance from the workpiece and redirected between machines or obstacles around the workpiece, whereas other welding methods cannot be used due to the above-mentioned space limitations.
