A conductive coupling is provided on the at least one magnet assembly. The conductive coupling is configured to be electrically coupled to the first end of the cable. The second end of the cable is configured to be detachably and electrically coupled to the second conductive member.

A welding method includes providing a first connector having a first end, providing a second connector having a second end for being welded to the first end, overlapping the first end and the second end, applying a contactless heating to a central section of the first end and melting an end section of the first end facing the second connector, and cooling the first end and the second end to form a weld connecting the first connector and the second connector. The first connector and the second connector extend in opposite directions from the weld.

A welding helmet for detecting arc data is provided. One embodiment of the welding helmet includes an arc detection system configured to detect one or more welding arcs that occur during one or more welding operations. The welding helmet also includes control circuitry configured to count a number of the one or more welding arcs detected by the arc detection system. The welding helmet includes a storage device configured to store the number of the one or more welding arcs.

An attaching and detaching apparatus includes a main mounting plate to which a main mounting object is to be mounted, an attachment mounting plate to which an attachment mounting object is to be mounted, and a connecting member between the main mounting plate and the attachment mounting plate. A protrusion projecting toward the connecting member is formed on the main mounting plate. A hole into which the protrusion fits is formed on the connecting member. A first contact surface in the shape of a surface of revolution is formed on the protrusion. A second contact surface in the shape of a surface of revolution is formed on the inner surface of the hole. The first contact surface and the second contact surface are in contact with each other with the central axis of the protrusion coinciding with the central axis of the hole.

This application relates to a protective apparatus. The protective apparatus is configured to protect a to-be-welded part, the to-be-welded part includes a welding region, and the protective apparatus includes a base and a protective mechanism. The base is configured for embedding the to-be-welded part. The protective mechanism is connected to the base. The protective mechanism includes a welding hole, where the welding hole is provided corresponding to the welding region; and a surface of the protective mechanism facing the welding hole is provided with a thermally conductive coating, where the thermally conductive coating is configured to guide substances formed in welding the to-be-welded part to slide down along the surface of the thermally conductive coating. The protective apparatus in this application can improve welding quality of the welding region, thereby enhancing performance of the to-be-welded part.
