Laser Welding Helmet vs Safety Glasses: Do You Need an Enclosure?
Laser safety glasses protect the eyes, while a laser welding helmet extends protection around the eyes, face and head. Neither one controls the laser radiation that can leave the workstation and reach other people. For high-power handheld laser welding or cleaning, a properly designed protective enclosure, access control and operating procedure may still be required. […]
How to Choose Laser Welding Wire Diameter: 0.8, 1.0, 1.2 or 1.6 mm?
Choose the laser welding wire diameter based on four factors: base-metal grade, sheet thickness, joint gap, and the wire-feeder path. A thinner wire gives finer control on thin sheet, while a larger wire adds more filler metal. However, diameter alone cannot determine whether a weld is good. The wire alloy, feed stability, laser parameters, fit-up, […]
Laser Welding Wire Feeds Unevenly? Check the Liner, Roller and Pressure
If laser welding wire feeds unevenly, do not begin by changing laser power or welding speed. First release the drive-roller pressure and pull the wire through the feed path manually. A wire that already feels tight points to the spool, liner, guide tube or welding nozzle. A wire that moves freely by hand but slips […]
