Modern welding has many energy sources, including gas flame, arc, laser, electron beam, friction and ultrasonic wave. Besides being used in factories, welding can also be carried out in various environments, such as outdoor, underwater and space.
No matter where, welding may bring danger to operators, so appropriate protective measures must be taken during welding. Welding may cause harm to human body, including burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.
The two sides of the extension data are perpendicular to each other, forming an angle, which can form various stressed members according to the different needs of the structure, and can also be used as connectors between members. Because of its good weldability, plastic deformation performance and certain mechanical strength, it is widely used in various building structures and engineering structures.
Such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, etc. In the installation and use of angle steel, it is necessary to cut its size. The existing angle steel cutting methods are mostly manual operation, which has high labor intensity and low cutting efficiency.
