The perfect settings for laser welding thin metal
When you sit down at your laser welder, Paul’s golden rule is simple: Start low and go higher.
Here, he’s working with wafer-thin metal, so he starts with very low power and a short weld time, testing with a single shot before increasing anything.
Once he’s reached the lowest settings he can use effectively, there’s another way to fine-tune the weld. By increasing the spot size, Paul can spread the energy over a larger area and reduce the power needed.
Once he’s found the optimum settings for the job, he can get on with welding confidently without worrying about blowing a hole through the material.
It’s all about finding the right combination of power, time and spot size.
