Handheld Laser Welding Parameters Reference
Optimized Welding Settings for Carbon Steel, Stainless Steel, and Galvanized Steel.
For complete beginners, learning welding can be a challenging task as there is an abundance of knowledge to master. Among them, setting up and adjusting the machine alone takes a considerable amount of time, and it can be exhausting before one fully grasps it.
Fortunately, all of our laser welding machines offer the automatic setting function for welding, which can automatically set the recommended parameters. However, not all welding machines have this feature.
If you need to manually adjust the parameters, we have compiled the welding parameters for common materials into a quick reference table to make it easier for you to use when starting a project next time. This guide covers the processes and metals that you, as a regular welder, are most likely to encounter.
The following parameters are based on Tonchel laboratory testing and practical production applications. Actual welding results may vary depending on material composition, surface conditions, and operator experience.
Why Parameter Optimization Matters
Higher Weld Quality
Stable penetration and clean weld appearance.
Faster Production
Increase welding efficiency while reducing rework.
Reduced Material Deformation
Optimized heat input minimizes distortion.

FAQ:
1. Are welding parameter charts always accurate?
No. Welding parameter charts are starting points, not fixed rules. The final result can change with metal condition, joint fit-up, machine type, shielding gas, welding position, and the welder's travel speed.
2. How should beginners use welding parameter charts?
Beginners should treat the chart as a safe starting point. Set the machine close to the recommended range, run a test bead on scrap metal, check penetration and bead shape, then make small adjustments until the weld looks and performs correctly.
