Better welding quality

Welding constancy can be achieved by a laser welder. Welding quality and consistency improved thanks to fiber laser technology. As a result, products would look nicer and more even surfaces fabricate.

Less heat, less Distortion

Laser welder uses less and concentrated energy for melting. It mainly reduces HAZ zone and result in much less distortion in parts fabricated.

Faster welding

It speeds up welding process compared to traditional stainless steel and aluminum TIG. As a result, laser welding reduces the total welding process cost per meter.

No post process

In traditional welding processes, almost always needs to spend long time for cleaning and preparing the welded surfaces. But with this newly developed technology, laser welding, in most cases no post process needs to be done.

Laser welder parameters

Welding Gun

• Smart internal design, good interactive control system, enlarged tolerance range of processing parts and weld width, and taking advantage of small laser spot and better weld formation.

• No Skilled Worker required!

While processing, wire filling welding or no wire filling is selectable, according to the product.

This laser welding machine system includes integrated touch screen control system, laser control system, galvanometer control system, and laser safety lock function. It has a variety of welding modes, the width of the spot can reach 0.2-5mm, which solves the uneven butt welding problems, and also the width of the beam is adjustable according to the actual product needs. This improves the fusion width and depth compared to traditional hand-held welding.

This laser welding system has adjustable beam and frequency setting (0-46HZ) to adjust the frequency according to the thickness of the plate, which solves the problem of over-burning caused by the high single-point power of traditional hand-held welding.

Different tips

There are 3 laser welding tips and one cutting tip, described below.

Handheld Laser Welding Process Reference

• The thicker the plate, the thicker the welding wire, the greater the power and the slower the wire feeding speed.
• The lower the power is, the whiter the welding surface will be, and the higher the power will be, the welding seam will change from light to black, and one side will be formed at this time.
• The thickness of the welding wire should not be larger than the thickness of the plate, and the thickness of the welding wire should affect the fullness of the weld
• The thinner the wire, the lower the scanning width

welding effect of 0.5mm stainless steel, inside corner

Parameter setting: 0.8 stainless steel wire, scanning speed 350, scanning width 2, peak power 350, duty
cycle 100, frequency 2000
As shown in Figure 10-1-1, the emitted light penetrates to the plate, and the amount of deformation is large, so we reduce the power to deal with it

Parameter setting: 0.8 stainless steel wire, scanning speed 350, scanning width 2, peak power 260, duty cycle 100, frequency 2000
The amount of deformation has been reduced, but it is still easy to burn through when the light is first emitted, so we continue to reduce the power. As shown in Figure 10-1-2.

Parameter setting: 0.8 stainless steel wire, scanning speed 350, scanning width 2, peak power 200, duty cycle 100, frequency 2000
The effect is shown in Figure 10-1-3, and when the width is increased to 3, it is shown in Figure 10-1-4.
The above parameters debugging process, are for reference only, and the actual conditions shall prevail.

For aluminum welding refer to the stainless steel process, and the power can be increased by 20%-30%. In addition, there are differences in focus, which need to be adjusted manually.

Wire feeder

Features

touch screen display, four-wheel dual-drive wire feeding mechanism, wire feeding speed 25-600cm/min (adjustable), support continuous wire feeding mode and pulse wire feeding mode

Wire details

0.8/1.0/1.2/1.6mm, 2.0/2.5mm can be customized

• Stainless steel welding wire is used for stainless steel materials
• Iron wire is used for carbon steel/galvanized sheet material
• Aluminum wire is used for aluminum material (we recommend using alloy aluminum above series 5 for aluminum welding wire, which has high hardness and is not easy to get stuck)

Welding Wire/Feed Roller Installation

CAUTION: DO NOT USE FLUX-CORED WELDING WIRE.

• Adjust the strength of the roller through the inner hexagon, to keep it not too tight or too loose, and there is no jamming during wire feeding (Factory preset, no need to adjust in normal situation)
• Cover the CAP after adjustment (Figure 11-1-2)

• There are two wire feed rollers working in one pair. The roller has two sizes of notch, corresponding to different welding wire diameters.
• Be sure to install it accordingly. If 1.2 welding wire is installed, the side with the 1.2 MARK on the wire feed roller is facing the outside of the machine.
• Be sure welding wire stick in the notch before fixing the clamp (Figurel1-1-3)

Installation of Wire Feeding Tube

Before installing the wire feed tube to the machine, first remove the copper nozzle at the other end of the tube. Install the corresponding size of copper nozzle only after finish installed the wire feeding tube metal part. (Figure 11-1-4)

Insert wire into the wire feeding tube, to a suitable position, and fasten the lock screw. (Figure 11-1-5)

Caution not to touch the wheel. (Figure 11-1-6)

Check to make sure you use the right size of welding nozzle to fit the welding wire. (Figure 11-1-7)
