Is laser welding machine strong

The main purpose of laser welding machine is to make a connection of sufficient strength between the two sides of the welding materials. The laser welder strength has a great relationship with the laser welding equipment power and the work speed as well as the welding material.

1. Under the same laser welding machine power, the welding speed directly affects the welder strength. The faster the laser welders peed, the narrower the weld seam, then the welding cannot be formed quickly. In other words, the faster the laser welder speed, the weaker the laser welding strength. Besides, the faster the welding speed, the shallower the penetration, so when welding thin plates or materials with better weldability, high-speed welding can be used, but it’s better to use low-speed when laser welding machine work on thick plates or difficult-to-weld materials.
2. When the laser welding machine speed remains the same, the higher the laser power, the better laser welder intensity. That is to say, when the laser welding machine’s power is increased from 1000W to 2000W, the penetration depth will increase and the laser welding strength will also increase.

Our Changtai company is currently doing strength experiments on handheld welding machines

1) 1000W laser welding machine can weld stainless steel within 3 mm.

2) 1500W laser welding machine can weld stainless steel within 5 mm.

3) 2000W laser welding machine can weld stainless steel within 8 mm.

If there is a relatively large weld (greater than 0.3mm) between the two materials, then we would recommend the customer to use an automatic wire feeder.

In addition, the laser welder strength is also affected by the welding material, no matter there is gas assist during welding or not. Different materials have different absorption of laser light. The surface state of the material (the degree of smoothness) has an important influence on the absorption rate of the laser; The shielding gas is assisted to prevent the workpiece from being oxidized during welding, protect the focusing lens, and dissipate the plasma shield generated during high-power laser welding. Then the welding strength will be further improved.

In summary, there is a suitable welding speed range for a certain laser power and a certain thickness of a specific material. When the relevant conditions are met, the laser welding machine strength is naturally very strong. It is definitely larger than the traditional welding process on the market.
