3 in 1 Laser Welding Parameters Setup

Operation Tips:

① The thicker the plate, the thicker the welding wire; the bigger the power, and the slower the wire feeding speed

② The less the power, the whiter the welding surface. The bigger the power, the weld seam will change from color to black, and the single-sided form will be formed at this time.

③ The welding wire should not be thicker than the plate thickness but closing to the plate thickness. The welding wire will also affect the fullness of the weld.

④ The thinner the weld wire, the less the scanning width.

Our Testing on Different Materials

Affected by different brands of lasers, the following processes use the following laser to do proofing tests. But it is for reference only, and need to be fine-tuned appropriately when using.

III. aluminium

The aluminum parameters refer to stainless steel parameters. The power can only be increased by 20%-30%. What’s more, there are also differences on the focus, which need to be adjusted manually.

Case 1: 0.5MM stainless steel internal corner welding

Test 1:

Feeding 0.8mm stainless steel wire

Scanning speed 350

Scanning width 2

Peak power 350

Duty cycle 100

Frequency 2000

The plate is penetrated, and big deformation, so we reduce the power.

0.8mm stainless steel wire

Test 2:

Feeding 0.8mm stainless steel wire

Scanning speed 350

Scanning width 2

Peak power 260

Duty cycle 100

Frequency 2000

The deformation has been reduced, but it is still easy to be burnt when the laser starts flowing out, that’s the reason why we continue to reduce the power.
