Laser welding is rapidly moving from a high-end industrial novelty into small fabrication shops, and this video documents that transition from the inside. RMFG bought a handheld laser welder, were told they needed a $9,000 training course to use it competently, and instead spent a few days figuring it out themselves — then filmed the whole learning curve.

What makes this worth watching is the honest documentation of the learning process. Rather than a polished demo from a manufacturer rep, you see real first attempts: where the beam likes to wander, how filler wire feeds compared to TIG, how wobble settings affect bead width, and where the technique fails on thin or contaminated material. For anyone considering a fiber laser welder for a small shop, this is exactly the kind of unvarnished experience report that's hard to find — most laser welding content online is either marketing or expert demos.

It also addresses a real question facing the trade right now: how much of the steep training cost is genuinely necessary versus gatekeeping? The answer here seems to be "less than vendors claim, but the safety and beam-control fundamentals matter." Expect practical tips on joint fit-up (lasers are far less forgiving of gaps than TIG), focal distance, and the surprises that come with a 1500W beam in the hands of someone used to a torch.
