Abstract
The utility model discloses a double-wire and double-power-supply CO2 welding gun comprising a gas filling nozzle, welding wires and power supplies, wherein the number of the welding wires in the gas filling nozzle is two, the number of the power supplies is two and the two power supplies supply power to the two welding wires respectively. The two welding wires can be connected in series or in parallel. When being used in series, the welding wires are arranged at front and rear, and are applicable to backing welding of thick plates; and the two welding wires also can be used in parallel, namely are arranged in parallel, and are applicable to filling and cosmetic welding. The two welding wires can be made of different materials or a same material. In the double-wire and double-power-supply CO2 welding gun, higher deposition rate and welding speed can be obtained, so that the working efficiency is improved by one time; the applicability is strong, the mechanical performance of welding joints is good, the splashing is less, electric arcs are stable, the droplet transfer is easy to control, the treatment cost before and after welding is reduced, so that the welding efficiency is greatly improved; and the CO2 welding gun can be matched with a portal frame welding operation system and a welding tractor is achieved, so that the cost performance is higher.
Description
Technical field
The utility model relates to a kind of welding gun, relates in particular to a kind of mariages dual power supply CO2 welding welding-gun.
Background technology
In hull construction, 30%～40% when accounting for the hull construction chief engineer during Welder, welding efficiency directly has influence on shipbuilding period and shipbuilding cost.In the segmentation of shipbuilding was made, steel plate at first needed to finish the welding of plane jigsaw.What thick plates adopted is multi-pass welding.The workmanship that the quality of plane jigsaw welding and efficient directly have influence on whole segmentation, the manufacturing cycle.Advantages such as the CO2 gas shielded arc welding is a kind of generally acknowledged efficient welding method during steel construction piece is built, and has the welding efficiency height, and is energy-conservation.Wherein the CO2 welding has accounted for about 70% of whole welding job amounts in shipbuilding industry, but employing at present all is monofilament CO2 welding.And CO2 welds the welding of inapplicable crin, can not resemble the welding wire that adopts ￠ 4-6mm the Lincoln weld.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned defective of existing single welding wire welding gun, a kind of mariages dual power supply CO2 welding welding-gun is provided.
The utility model comprises that inflation is chewed, welding wire and power supply, and the welding wire number was two in inflation was chewed, and the power supply number is two, gives the power supply of two welding wires respectively.
But two welding wire serial or parallel connections of the utility model.Series connection is used, and promptly welding wire one in front and one in back is applicable to the slab backing welding; Also Ke And joins use, and promptly Han Si And row are provided with, and is applicable to and fills and cosmetic welding.
Two welding wires of the utility model can be made by similar and different material.
The utlity model has following superiority: 1, a workman can operate two CO simultaneously
2Gas shielded welding machine can obtain higher deposition rate and speed of welding, and work efficiency doubles.2, arc stability uses two kinds of electric arcs in same molten bath, and the arc energy of the 2nd root bead silk improves the circulation of liquid welding pool, reduces pore.3, the applicability of mother metal kind is strong, the weld seam satisfactory mechanical property.4, when deposition efficiency increases, keep lower heat input, preceding road weld seam has pre-heat effect to road, back weld seam, and back silk sweating heat input is low, distortion is little, saves power supply 20%.5, splash little, arc stability, the droplet transfer is controlled easily, reduces after welding treatment cost before the weldering, has improved welding efficiency greatly.6, welding changes into 1 time by 2 times, can save CO2 gas 15%.7, welding gun can rotate, and can connect also can join with And, and series connection is used for backing welding, and preceding road weld seam can be used impulse welding.The welding coverage is widened, low to the assembly precision requirement, the swing when having avoided welding.8, mariages dual power supply CO2 welding can be supporting with portal frame welding operation system and welding tractor, and cost performance is higher.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is provided with figure for the utility model embodiment 1 welding wire part;
Fig. 3 is provided with figure for the utility model embodiment 2 welding wire parts.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is set up a welding wire and power supply on the basis of existing single welding wire welding gun, comprise that promptly two welding wires and two give two welding wire power supplies, two welding wire serial or parallel connections respectively.
Referring to Fig. 1,2, present embodiment is packaged in same inflation by two welding wires 1 and chews in 2 and constitute, and 1 series connection of two welding wires one in front and one in back, and connects 3, two welding wires of two power supplys respectively and is manufactured from the same material.
Referring to Fig. 1,3, present embodiment is packaged in same inflation by two welding wires 1 and chews in 2,1 parallel connection of two welding wires, and connect 3, two welding wires of two power supplys respectively and make by different materials.
Claims (3)
1. mariages dual power supply CO2 welding welding-gun comprises that inflation is chewed, welding wire and power supply, and it is characterized in that: the welding wire number was two in inflation was chewed, and the power supply number is two, gave the power supply of two welding wires respectively.
2. mariages dual power supply CO2 welding welding-gun according to claim 1 is characterized in that: two welding wire serial or parallel connections.
