Multiple protection assemblies are arranged on the housing, each protection assembly is provided with a welding area communicated with the protection cavity, the welding area penetrates through the protection assembly, and the welding area is used for allowing a tip to pass through and perform welding. A driving assembly is arranged on the protection main body, the driving assembly is used for driving the protection assemblies and / or the protection main body to move so as to enable at least one protection assembly and a corresponding protection cover to move, and the direction of extension and retraction of each protection cover is arranged in the corresponding direction of movement of the protection assembly.

The application discloses a kind of stable welding equipment for steel structure, it is related to steel structure welding technical field, including welding machine component and base, welding machine component is fixedly installed in the back of base, the upper surface of base is provided with welding platform, welding auxiliary mechanism, the welding auxiliary mechanism is set on the upper surface of welding platform, the welding auxiliary mechanism includes the pressing frame being set on the upper surface of welding platform, the upper surface of the pressing frame is fixedly connected with two connecting strips, multiple cover plates are inserted in the inside of the connecting strip, the lower surface of the cover plate is fixedly connected with the guide piece, the surface of multiple cover plates and guide piece is all provided with guide groove, guide column is slidably inserted in the inside of the guide groove, to solve that argon is only temporarily in the weld position of welding head, in the process of welding head movement, the weld that has not yet solidified or has solidified but still has high temperature still contact with external oxygen, leading to the outer layer of weld and a large amount of oxygen contact problem.

Provided is a welding information providing apparatus including a main body provided to be worn by a user, a display unit, which is arranged in the main body and includes a display for displaying a welding image to the user, a primary lens member, which is arranged on a path through which the welding image provided from the display travels, and includes a convex surface for adjusting a size of the welding image to allow the welding image to reach both eyes of the user, at least one camera, which is mounted on an outer side of the main body and is configured to obtain a welding image frame with respect to a welding operation, and a processor configured to control the display to display the welding image generated based on the welding image frame.

The present invention relates to a welding spatter protection device (1) comprising: - a support structure (2); - a movable structure (10), which delimits a first internal shielding cavity (11) by means of a plurality of internal side walls (11a,11b,11c,11d) and is movable with respect to said support structure (2) by means of a first actuator (15) between a lowered position, in which in use said first internal cavity (11) is placed astride the welding zone, and a raised position, in which in use said first internal cavity (11) is moved away from said welding zone, - a cleaning system (20) for cleaning the internal side walls (11a,11b,11c,11d) of said first internal cavity from welding spatter, comprising a scraper (21). Two second walls (11c,11d) interconnect said two first walls (11a,11b) to each other and define two concentric cylindrical surfaces. The scraper (21) is rotationally connected to said movable structure (10) by means of a support arm (22) which is pivoted on a rotation axis (Y1) coincident with the axis (O) of said two concentric cylindrical surfaces (11c, 11d) and supports said scraper (21), keeping it aligned on a radial plane, said support arm (22) being actuatable by means of a second actuator (25). The circumferential ends (11c',11c";11d',11d") of said two concentric cylindrical surfaces (11c,11d) at an inlet mouth (12) and at an internal stop position are radially aligned so that the scraper (21) is always in contact with said two concentric cylindrical surfaces (11c,11d), said two concentric cylindrical surfaces (11c,11d) being oriented so that the radially outermost cylindrical surface (11c) extends beyond the bottom wall (10a) of said movable structure (10), defining a shielding appendage (16).

A head-mounted optical protection device includes a lens clamp assembly that facilitates the addition and / or removal of at least one lens of a plurality of lenses. The head-mounted optical protection device can be a welding helmet that is particularly suited for laser welding applications. The lens clamp assembly includes one or more lens clamps that engage one or more lenses and hold the lenses against a lens frame in a main body of the protection device. In one embodiment, the lens clamp assembly can include a releasable lens clamp with an actuator that releasably engages the lens frame and facilitates the removal of a lens in a stack of lenses. In another embodiment, the lens clamp assembly can include an outer lens clamp for securing a ballistic protective lens in an outer portion of the lens frame and a separate inner lens clamp for securing an optical lens, such as a DIN rated lens, in an inner portion of the lens frame.

A welding image processing device and method are provided. The welding image processing device includes: a camera unit configured to capture an image of a welding portion; a cartridge arranged to be adjacent to a camera module; and a processor. The processor is configured to control a transmittance of the cartridge on the basis of a sensor value received from a sensor and acquire a welding image through the camera unit on the basis of light passing through the cartridge having the controlled transmittance.
