Laser Welding Process Parameter Aviation Laser Services © 2025 Follow these principles when welding ① The thicker the plate, the thicker the welding wire； the greater the power, and the slower the wire feeding speed ② The lower the power, the whiter the welding surface. The greater the power, the weld seam will change from color to black, and the single-sided form will be formed at this time. ③ The thickness and fineness of the welding wire should not be larger than the plate thickness instead of closing to the plate thickness. The welding wire will also affect the fullness of the weld. ④ The thinner the weld wire, the lower the scanning width. 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 ①RECI / MAX / JPT ②Argon

What’s more, there are also differences in the focus, which need to be adjusted manually. Reference: 0.5mm stainless steel internal corner welding The scanning speed of 0.8 stainless steel wire is 350, the scanning width of it is 2, the peak power of it is 350, the duty cycle of it is 100, and the frequency is 2000. The light penetrates the plate, and the amount of deformation is very large, so we take action of reducing the power.

Laser Welding Process Parameter Aviation Laser Services © 2025 jamie@aviationlaser.com The scanning speed of 0.8 stainless steel wire is 350, the scanning width of it is 2, the peak power of it is 260, the duty cycle of it is 100, and the frequency is 2000. The amount of deformation has been reduced, but it is still easy to be burnt when the light starts flowing out, that’s the reason why we continue to reduce the power in the process. The scanning speed of 0.8 stainless steel wire is 350, the scanning width of it is 2, the peak power is 200, the duty cycle of it is 100 and the frequency is 2000. The effect is as follows ①. When you increase the width to 3 is as it shown in figure ②.
