\ud83d\udd0d What Is a CNC Laser Welding Machine?<\/span><\/h2>\n

A\u00a0<\/span>laser welding machine<\/span><\/strong>\u00a0is a precision joining system that uses a high\u2011energy laser beam as the heat source to melt and fuse materials. Compared to traditional welding (e.g., TIG), laser welding is much faster, produces a very small heat\u2011affected zone (HAZ), creates clean seams, and is easy to automate.<\/span><\/p>\n

  • \n

    Beam oscillation (wobble)<\/span><\/strong>\u00a0\u2013 The laser beam moves in a controlled circular or figure\u2011eight pattern. This widens the weld, reduces porosity (especially in aluminium), and improves joint quality.<\/span><\/p>\n<\/li>\n

    Galvo scanner welding<\/span><\/strong>\u00a0\u2013 A high\u2011speed scanning mirror moves the beam very quickly across the workpiece \u2013 ideal for micro\u2011welding and high\u2011throughput applications.<\/span><\/p>\n<\/li>\n<\/ul>\n
