Chapter 6 Operation Guide
Remark
1. The welding form is splicing welding, the welding head ratio is 50:150,
and the core diameter of the 1500W laser fiber is 50 microns
2. Welding shielding gas: nitrogen (purity 99.99%)
3. Power percentage (1500w) 10-100%, swing amplitude 0-4mm
(recommended 2-3mm), swing frequency 0-220hz (recommended manual
welding frequency 40-80hz, air flow not less than 15l/min), other parameters
are not In the case of change, the swing amplitude or welding speed
increases, and the laser power also needs to be increased accordingly
4. Welding speed=welding length/welding time
5. Due to the difference in welding process (air pressure, manual speed,
defocusing degree, welding angle) of different customers, this data is for
reference only.
NOTICE:
◎
Stack welding, fillet welding, lap welding, etc. can refer to the above process
parameters.
