Abstract
The invention provides a welding method. In the method, two electrodes of a welding power supply are respectively connected with welding materials through cables; two welding materials are in overlapped joint with the same weldment; a loop is directly formed by means of two polar welding materials; and welding is performed. The welding method improves the welding efficiency, reduces electric energy computation, and can be widely applied to welding equipment, such as handle welding machines, carbon dioxide arc welding machines, submerged-arc welding machines, metal argon-arc-welding machines and the like.
Description
(1) technical field
The present invention relates to a kind of welding method.
(2) technical background
Welding is a kind of by heating or pressurization, or both and usefulness, and with or without packing material, make workpiece reach the technological method for processing of combination.
Workpiece can be with various similar or inhomogeneous metals, nonmetallic materials (plastics, graphite, pottery, glass etc.), also can be with a kind of metal and a kind of nonmetallic materials.Being welded on of metal has application widely in the modern industry.
According to the residing state difference of metal material in the welding process, at present welding method is divided into following three classes:
(1) melting welding: in the welding process, the weldment joint is heated to molten state, the plus-pressure method of finishing welding is not called melting welding.Fusion welding method commonly used has arc welding, gas welding, electroslag welding etc.
(2) pressure welding: in the welding process, must exert pressure to weldment (heat or do not heat) is called pressure welding with the method for finishing welding.Press welding method commonly used has electric resistance welding (butt welding, spot welding, seam weldering), friction welding (FW), rotating arc welding, supersonic welding etc.
(3) soldering: in the welding process, employing is made solder than the low-melting metal material of mother metal, weldment and solder are heated to above the solder fusing point, are lower than the temperature of mother metal fusing point, utilize the wetting mother metal of liquid solder, fill the play movement and with mother metal mutually counterdiffusion realize that the method that connects weldment is called soldering.Method for welding commonly used has gas brazing, induction brazing, furnace brazing, salt bath brazing and vacuum brazing etc.
The welding method of present technology, be that positive pole with the source of welding current connects wlding by cable, the negative pole of the source of welding current joins by cable and weldment, when wlding contacts with weldment, just formed the loop, thereby weld, there is the low and big defective of electric energy loss of welding efficiency in this welding method.
(3) summary of the invention
Technical assignment of the present invention is at the deficiencies in the prior art, and a kind of welding method that improves welding efficiency, reduces electric energy loss is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of welding method, the two poles of the earth of the source of welding current are connected with wlding respectively by cable, and two wldings overlap same weldment, rely on two polarity wldings directly to form the loop, weld.
Above-mentioned welding method, its source of welding current are DC welder or AC welding set.
Above-mentioned wlding is a welding rod.
A kind of welding method of the present invention compared with prior art, the beneficial effect that is produced is:
1) the two poles of the earth of the source of welding current all connect wlding, rely on two polarity wldings directly to form the loop, weld, and have so both improved welding efficiency, have also reduced the consumption of electric energy.
2) be suitable for welding equipments such as handgrip weldering, carbon dioxide gas arc welding, submerged-arc welding, metal argon arc welding.
(4) description of drawings
Accompanying drawing 1 is a theory structure schematic diagram of the present invention.
Among the figure, 1, the source of welding current, 2, cable, 3, cable, 4, wlding, 5, wlding, 6, weldment.
(5) specific embodiment
Below in conjunction with explaining below 1 pair of a kind of welding method work of the present invention of accompanying drawing.
As shown in Figure 1, a kind of welding method of the present invention is that the two poles of the earth with the source of welding current 1 are connected with wlding 5 with wlding 4 respectively with cable 3 by cable 2, wlding 4 and the same weldment 6 of wlding 5 overlap joints, rely on two polarity wldings 4 and wlding 5 directly to form the loop, weld.
The above-mentioned source of welding current 1 is DC welder or AC welding set; Wlding 4 and wlding 5 are welding rod.
Its processing and fabricating of a kind of welding method of the present invention is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Claims (4)
1. a welding method is characterized in that, the two poles of the earth of the source of welding current are connected with wlding respectively by cable, and two wldings overlap same weldment, relies on two polarity wldings directly to form the loop, welds.
2. a kind of welding method according to claim 1 is characterized in that, the source of welding current is a DC welder.
