The maximum thickness a laser welding machine can weld and whether it will burn through thin sheets depends on several factors. Here are the specifics:
Maximum welding thickness of laser welding machines:
There is no absolute limit to the maximum material thickness a laser welding machine can weld. Generally speaking:
1000 watts: Can weld sheets up to about 3mm thick.
2000 watts: Can weld materials approximately 3mm-4mm thick, and under certain conditions can also weld carbon steel and stainless steel up to about 5mm.
3000 watts: Can weld materials around 5mm thick.
High power and special application laser welding machines: In some advanced industrial applications, such as shipbuilding, bridge construction, and heavy machinery manufacturing, high-power laser welding equipment can easily handle the welding of steel plates with thickness up to several tens of millimeters.
Will welding 0.5mm or thinner sheets burn through?
When welding sheets below 0.5mm, if the operation is improper or the equipment parameters are not suitable, it is possible to burn through, but this can be avoided by reasonable control, as follows:
Reasons for easy burning through:
Laser energy concentration: Laser welding has high energy density and concentration, while thin sheets have low heat capacity. Under the action of the laser, heat accumulates quickly, and the temperature rises rapidly, easily reaching the vaporization temperature of the material, thus leading to burning through.
Difficulty in power control: Welding thin sheets requires extremely precise control of laser power. Conventional power control may not meet the precision needs of thin sheet welding, and slight power fluctuations can cause burning through.
Measures to avoid burning through:
Precise control of laser parameters: Reasonably reduce laser power, choose shorter pulse widths and higher frequencies to ensure that while melting the material, excessive heat accumulation is avoided.
Use appropriate welding processes:For example, use pulse welding methods to output laser energy in pulse form, making the heat input during the welding process intermittent, reducing heat accumulation. Modulated pulse mode can also be used to further reduce the heat input during the welding process.
Use of shielding gases: Choose the right shielding gases such as argon or helium, and adjust the gas flow rate to effectively protect the welding area, reduce the production of oxides and other ionized bodies, improve weld quality, and help reduce the risk of burning through.
Improve operational skills: Operators need to have rich experience and proficient skills to precisely control welding speed, welding path, etc., ensuring the stability of the welding process.
