Steel fiber laser cutting common problems and solutions

Fiber laser carbon steel cutting

Problem

Reason

Solution

fiber laser cutting

Layered at the bottom, wrinkles appear

1. Atmospheric pressure


2. Low focus


3. Nozzle is too large

1. Reduce air pressure


2. Improve focus


3. Use a small nozzle

fiber laser cutter

Small streaks appear on the section

1. Excessive air pressure


2. Cutting speed is too slow

1. Reduce air pressure


2. Speed up the cutting


fiber laser machine

There are welding slag and welding spots 

on the bottom

1. Low air pressure


2.Focus is too low


3.Small nozzle


4.Fast cutting speed

1. Increase air pressure


2. Improve focus


3. Change the large nozzle


4. Reduce cutting speed

Burnt at the bottom

1. Too much energy


2. Excessive air pressure


3. Cutting speed is too slow

1. Reduce peak power


2. Reduce air pressure


3. Speed up the cutting

iron cutting fiber laser

Bad cut on the side

1. Polarized light


2. Protect the lens from dirty


3. Cutting speed is too fast


4. The nozzle is not round or the nozzle is blocked

1. The center of dimming


2. Clean the protective lens or replace the protective lens


3. Reduce the cutting speed

4. Replaced nozzle

metal laser cutting machine

Small fine lines on the section with molten iron at the bottom

1. Cutting speed is too slow 1. Speed up the cutting speed

unique cnc metal fiber cutter

Hot metal on the surface

1. Cutting speed is too fast


2. The air pressure is too low


3. Wrong focus

1. Reduce the cutting speed


2. Increase the air pressure


3. Adjust focus

Sectional Twill

1. Cutting speed is too fast 1. Reduce the cutting speed

fiber cutting machine

There are fine strips on the upper section of the cutting.

1. The focus is too high


2. Excessive air pressure

1. Reduce focus


2. Reduce air pressure

Horn burn

1. Cutting heat is too high

1. Round the sharp corners


2. Use cooling points


3. Use power curve



Fiber laser stainless steel cutting

Problem
Reason Solution

ss cutting fiber laser machine

Striped hard slag hanging on the bottom

1. The focus is too high


2. Air pressure is too low

1. Reduce focus


2. Set bigger air pressure

stainless steel fine cutting

The lower part of the section is whitish


1. The focus is too high


2. The cutting nozzle height is too low


3. Excessive air pressure

1. Reduce focus


2. Increase the nozzle height


3. Reduce air pressure

stainless steel fiber laser cutting

Yellowing at the bottom of the section

1. The focus is too high

1. Reduce focus

fiber laser cutting machine for ss

Small drop-like burrs on the bottom

1. Too fast


2. Low focus

1. Reduce the cutting speed


2. Improve focus

a5

Corner dregs

1. High focus 1. Reduce focus

fiber cutting for ss

The slit becomes wider

1. Protect lens are dirty 1. Replace the protective lens

a7

Rough section, blue light appears in the seam during cutting

1. The focus is too low


2. Cutting speed is too fast


3. The knife is not set

1. Improve focus


2. Reduce the cutting speed


3. Use a slow starting point for starting the knife or use a round hole at the starting point of the lead to introduce

ss fiber cutting

One side or both sides are not cut well, the other side is cut well

1. Polarized light


2. Protect the lens from dirty


3. The coaxial is not good


4. The nozzle is not round

1. Check the center of the light


2. Clean or replace the protective lens


3. Check the coaxial


4. Replaced nozzle

a9

Yellow section

1. The gas is impure


2. Air or oxygen in the trachea

1. Nitrogen purity requirement 99.99%


2. Check the gas path


3. Check delay


Fiber laser cutting carbon steel perforation process

Problem

Reason

Solution

fiber laser cutting machine

Light blasthole



1. Perforation frequency is too high


2. Punching power is too large


3. Too much air pressure


1. Reduce frequency by 10% each time


2. Reduce the duty cycle, 1%-2% each time

3. Reduce air pressure,0.1bar each time

c2

Blast hole during piercing



1. Perforation frequency is too high


2. Punching power is too large


3. Too much air pressure



1. Reduce frequency by 10% each time


2. Reduce the duty cycle, 1%-2% each time


3. Reduce air pressure, 0.1bar each time

c3

End of piercing and start cutting blasthole

1. Insufficient punch time


2. Punching power is low


1. Increase the punching time, every time

0.5sec


2. Increasethepunchingpower, 5% eachtime


3. Increase the duty cycle, every time 

1%-2%


4. Use slow start
