Hand-push type flat plate welding tail heat-dissipating protection device

Abstract

The invention discloses a hand-push type flat plate welding tail heat-dissipating protection device. The hand-push type flat plate welding tail heat-dissipating protection device comprises a flat plate, a protective cover, heat-dissipating fans and a water circulating pipeline, wherein the protective cover covers above a weld joint of the flat plate; a plurality of exhausting holes are reserved in the top of the protective cover; each heat-dissipating fan is oppositely arranged at each exhausting hole; air inlet holes are formed in the two side walls of the protective cover correspondingly; a water storage tank is assembled on the tail part of the protective cover; the water circulating pipeline is arranged in the protective cover; and one end of the water circulating pipeline is connected with a water pump in the water storage tank, and the other end of the water circulating pipeline is inserted into the water storage tank after multi-stage circulation. The hand-push type flat plate welding tail heat-dissipating protection device is exquisite in structure and convenient to use, comprehensively utilizes heat conduction and heat convection heat transfer modes to realize quick cooling of a weld joint area in the welding process, meets the actual welding requirement and improves the welding efficiency.

Description

technical field [0001] The invention belongs to the plate welding technology, in particular to a tail heat dissipation protection device for hand-push plate welding. Background technique [0002] Flat welds are the most common type of welds in the welding process, and flat welds are widely used in shipbuilding and rail transit. Since the plate welding process is mostly multi-layer multi-pass welding, that is, multiple multi-layer welding is performed in the same weld, the temperature of the previous layer of weld before the next layer of weld will have an impact on the quality of the weld. Therefore, in the actual welding process, before the next welding, because the previous layer of weld has not cooled to a certain temperature value, it is necessary to wait for a period of time before the next welding, which greatly reduces the welding efficiency. At the same time, the excessive contact between the weld pool and the external environment during the welding process will cau...
