Abstract

The utility model relates to a large-diameter carbon-dioxide arc welding wire, which is made by winding and combining six welding wires around a welding wire. The welding wires are continuously wound by a special-purpose device into a large-diameter carbon-dioxide arc welding wire, the outer diameter of which is above 2.4mm. If the chemical composition of the material of the central welding wire is changed, various carbon-dioxide arc welding wires of different standards such as stainless steel, low-alloy steel and the like can be achieved. The utility model has a remarkable energy-saving effect, and the energy consumption of the utility model is as much as 30 to 40 percent of a prior carbon-dioxide welding wire; efficiency is remarkably improved, an ordinary welding seam can be completed with one to two times, and efficiency is improved by 3 to 4 times; the utility model can be arbitrarily coiled; the utility model can be used for three-dimensional welding; the utility model is simple in manufacturing technique, good in usability and wide in practicability.

Description

The large-diameter carbon-dioxide gas protecting welding wire
Technical field
The utility model relates to the large-diameter carbon-dioxide gas protecting welding wire, is particularly useful for the welding of various different metals and alloy material.
Background technology
Since the last century the eighties, expanded in industries such as machine-building, shipbuilding, automobile making, engineering machinery, coal mine machineries with the welding new method, new material and the new technology that are welded as representative automatically; The carbon dioxide gas shield welding wire has that energy-efficient, welding performance is good, the technology applicability is strong, is easy to realize semi-automation and advantage such as automation welding with it, and is with the fastest developing speed in welding profession; It more and more is subjected to people's favor as the substitute products of welding rod.At present, the welding wire specification of domestic welding wire manufacturer production is 1.6 millimeters of Ф 0.8~Ф; Do not occur greater than the welding wire more than 2.4 millimeters for gage of wire, its reason is always: 1) along with gage of wire strengthens, and the proportional increase of its welding current, and welder power is infinitely increased, the workman can't operate.2) gage of wire strengthens, and its Pan Yuan can't carry out at all.3) general major diameter welding wire only can use in submerged arc welding, but can not carry out continuously uninterrupted welding, can only carry out the level welding, and the welding space is restricted.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of textural association, the large-diameter carbon-dioxide gas protecting welding wire that be convenient to process, welding effect is good.
Large-diameter carbon-dioxide gas protecting welding wire of the present utility model; it is closed around center one root bead skein silk by six roots of sensation welding wire and forms; be coated with copper protective layer respectively on every root bead silk, the every root bead filament diameter that is combined into one is identical, and the diameter of every root bead silk is equal to or greater than 0.8mm.
Can add nickel, chromium, manganese, the titanium that changes its chemical analysis respectively in the material of cored welding wire in described.
Large-diameter carbon-dioxide gas protecting welding wire of the present utility model is applicable to the welding of various different metals and alloy material.Seven identical larger-diameter welding wires that are coated with copper protective layer respectively of diameter are combined, and welding wire is coiled into a large diameter carbon dioxide gas arc welding silk by the special equipment system of continuously twisting; Its external diameter if change the chemical analysis of that root bead wire material that is located at the centre, can obtain the carbon dioxide gas arc welding silk of different cultivars more than 2.4 millimeters.Compared with prior art, 1) energy-saving effect is fairly obvious, only is 30~40% of former carbon dioxide welding wire; 2) labor productivity obviously improves, and welding one normal weld originally needs 6~7 times, and only 1~2 time now, improve 3~4 times of effects; 3) Pan Yuan arbitrarily; 4) can carry out the omnibearing stereo welding.Its production technology is simple, and serviceability is good, has practicality widely.
Description of drawings
Fig. 1 is welding wire cross-sectional structure figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Shown in Figure 1, large-diameter carbon-dioxide gas protecting welding wire of the present utility model is made of seven identical solid welding wires of diameter, and every solid welding wire outer surface is coated with copper protective layer, and the six roots of sensation solid welding wire 1 in the seven root bead silks is around middle solid welding wire 2.In the identical thin welding wire of seven diameter, the diameter of every thin welding wire can be respectively: 1.6 millimeters of Ф 0.8, Ф 1.0, Ф 1.2, Ф and more than, for example, when the thin welding wire diameter that adopts is: during 1.0 millimeters of Ф, optional its seven stranded and form a diameter and be: the carbon dioxide gas arc welding silk that Ф is 3.0 millimeters; Therefore, adopt single thin welding wires such as 1.6 millimeters of Ф 0.8, Ф 1.0, Ф 1.2, Ф respectively, can obtain the carbon dioxide gas arc welding silk of Ф 2.4, Ф 3.0,4.8 millimeters of Ф 3.6, Ф and above different size respectively.Change the chemical composition of the solid welding wire 2 that is located at heart portion, in its material, add nickel, chromium, manganese, titanium respectively, can obtain carbon dioxide gas arc welding silks different size, many kinds such as stainless steel, low-alloy steel.

Claims (1)

1. large-diameter carbon-dioxide gas protecting welding wire; it is characterized in that: it is stranded around center one root bead silk (2) by six roots of sensation welding wire (1) to be one; be coated with copper protective layer respectively on every root bead silk, the every root bead filament diameter that is combined into one is identical, and the diameter of every root bead silk is not less than 0.8mm.
