The invention belongs to the technical field of
metal welding and thermal
cutting and discloses a
metal welding and
cutting device which comprises a
machine base, a guide rail is fixedly connected to the side wall of the
machine base, a control panel is installed on the side wall of the
machine base, a
laser is installed on the top face of the machine base, and a rotary disc is rotationally connected to the side wall of the
laser. The device has the advantages that the positions of a
laser focus and a material can be automatically adjusted, the influence on the
metal welding and
cutting quality is avoided,
program control is not needed, the device can adapt to
machining of materials with various shapes, the material
machining cost is greatly reduced, meanwhile, the use of control elements is also greatly reduced, the difficulty of wire arrangement is avoided, and the production efficiency is improved. The application range of the device is expanded, metal welding cutting and metal fixing can be conducted at the same time, step-by-step operation is not needed, the hidden danger of misoperation is avoided, meanwhile, the
operation time can be saved, the lowest point of the metal surface can be rapidly determined, and therefore the focus point of a laser beam can be rapidly determined.
