Difference of 20&30&50w fiber laser marker
In recent day, more and more customers ask for the fiber laser marker.
As we know, there are different power fiber laser marking machine.
For example, 20w fiber laser marking machine, 30 w, 50w etc.
Some customers may wonder what is the detailed difference between the different power?
This passage will give some introduction about the fiber laser marker.
1.The difference of different power fiber laser marker
First of all,30w is more durable than 20w , and 50w is more durable than 30w fiber laser marker.
Secondly, if marking same content on same materials, 50w marking speed is faster than 20w 30w
At last,if marking same depth on same material, 50w marking time is shorter than 20w 30w.
In Technical side, following is reason:
(1.)Single pulse energy
The higher laser power the higher single pulse energy,for example,if we want to mark 0.1mm deep marker on metal,
we should repeat marking for 30 times if we use 20watt machine,and if we use 30watt machine to do the same mark, it maybe need no more than 20 times, and if we use 50watt machine to do the same mark, it maybe need no more than 10 times,
in brief,big power laser machine have greater efficiency.
(2.)Peak power (P.P.)
The P.P. of 20watt is 8000w,P.P. of 30watt is 9000w, P.P. of 50watt is 15000w, big Peak power have big laser strength.
