2816 results about "Arc welding" patented technology

Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Arc welders can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes.

Device for realizing laser welding and seam tracking and control method thereof

The invention relates to a device for realizing laser welding and seam tracking and a control method thereof.

Workstation system with welding robots for radar structural parts

ActiveCN103192159AExpand the scope of workEnsure quality and efficiencyWelding accessoriesRadarControl system
The invention relates to a workstation system with welding robots for radar structural parts. The workstation system overcomes shortcomings of low welding efficiency and difficulty in guaranteeing quality due to the fact that existing large radar structural parts are welded manually. By the aid of the workstation system, the large radar structural parts can be automatically and efficiently welded. The workstation system with the welding robots comprises two arc welding devices, the two welding robots, a gantry type slide rail, positioners and a control system device. The arc welding devices are connected with the welding robots, the welding robots are mounted on the gantry type slide rail, the positioners are arranged below the welding robots, and the control system device is respectively connected with the arc welding devices, the welding robots, the gantry type slide rail and the positioners and can control movement trajectories and welding procedures of the welding robots and movement of the positioners. The workstation system has the advantages that the large laser structural parts can be subjected to whole-process efficient automatic MIG (metal inertia gas welding)/MAG (metal active gas welding), the welding quality is improved, the labor intensity of workers is reduced, and the welding efficiency is improved by 4-5 times.
