Robotic TIG welding relies on multi-axis industrial robots paired with a dedicated TIG welding system. It uses a non-consumable tungsten electrode to ignite the electric arc, with argon gas shielding the molten pool from air throughout the entire process. By precisely programming and controlling the welding torch trajectory, welding current and travel speed, it can realize autogenous welding or automatic wire filling welding. The welding process features no spatter, aesthetic and dense weld formation, low heat input, and controllable workpiece deformation, making it compatible with various materials such as stainless steel, aluminum alloy and titanium alloy. Supporting automated continuous operation, it delivers high welding accuracy and strong product consistency, effectively improving the working environment. It is widely applied in high-precision welding scenarios including precision hardware, pressure vessels, medical devices and automobile parts.
