I. Laser welding machine advantages
1. Laser welder welding seam is beautiful, uniform, free of welding scar and discoloration, and does not need to be polished in the later stage. Save labor hours.
2. The welding is firm, and the weld strength reaches or even exceeds the base metal itself;
3. One time welding forming, basically no deformation, meeting the requirements of high quality products
4. Welding speed is fast, 4-10 times faster than traditional welding, a machine can save at least 2 welders a year。
5. Fiber laser welder operation is simple, easy to learn and fast to start, the operator's technical threshold is not high, and the labor cost is saved.
6. Low cost, power consumption is only 1 / 10 of that of general argon arc welding or gas shielded welding。
7. Red light positioning, more accurate welding position.
8. It can weld all kinds of metal materials such as carbon steel, stainless steel, aluminum plate, copper plate etc.
9. It is suitable for tailor welding, overlap welding, internal and external fillet welding, circular arc welding, irregular shape welding etc;
10. Handheld laser welder widely used in many industries, such as kitchen, household appliances, advertising, mold, stainless steel doors and windows, handicrafts, household products, furniture, auto parts, etc.

| Paint（120um) | 8m²/h | 12m²/h | 16m²/h |
| Rustiness（100um) | 5m²/h | 8m²/h | 10m²/h |
Welding Wire
According to the different welding plates, we need to use different welding wires (gas shielded solid welding wire)
* Stainless steel ：stainless steel welding wire such as: ER304
* Carbon steel/galvanized sheet：iron wire
* Aluminum：aluminum wire (we recommend using alloy aluminum above series 5 for aluminum welding wire, which has high hardness and is not easy to get stuck)
Protective gas
① Nitrogen or argon are commonly used. For welding stainless steel, we recommend using nitrogen, which has a better welding effect. Do not use mixed/carbon dioxide gas.
② Air pressure requirements: the flow meter is not lower than 15, the pressure gauge is not lower than 3

3in1 laser welding and |
welding cutting and cleaning |
1. Main function is welding. 2. when cutting,only need to change to cutting nozzle. This cutting function is manual, cutting thickness is less than cnc laser cutting machine cutting thickness. 3. When cleaning, (1)Don’t need to change focus lens. Cleaning width is only 20mm. (2)Change focus lense.cleaning width is 30-120mm(different power) |

Note: 2.The above gas welding blowing pressure is set between 0.3 MPa and 0.5 MPa by adjusting the pressure regulating valve 3.Suggest gas using Nitrogen, using pure air, surface is not as good as using nitrogen. 4.Laser power from 1000w -3000w, When choosing machine, it is recommended to choose a larger power based on the thickness in the table. 5. Aluminum is a highly reflective material. When welding aluminum, the life of nozzle lenses and laser welding heads will decrease. |
