Quick comparison of published capability
These are different manufacturer claims under different assumptions; they are not a standardized head-to-head test.
Why generic wattage charts can mislead
A wattage-only chart can hide important differences in alloy, joint design, wire use, focus, travel speed and what the manufacturer means by “maximum.” We therefore do not normalize every machine into a single universal promise.
Use the interactive explorer
For buyer research, the fastest workflow is to enter your routine material and thickness into our Thickness & Capability Explorer. It only returns models where we have a published source for the selected material.
Frequently asked questions
Is a 1500W laser welder always good for the same thickness?
No. Published thickness varies by manufacturer, material, configuration and test assumptions.
Is maximum thickness the same as ideal production thickness?
No. A published maximum is not necessarily the best continuous-production operating point. Ask the manufacturer to validate your exact joint and throughput requirement.
