Abstract
The utility model discloses a kind of cable formula welding wire, including：Central hair and curl up in the peripheral silk of central hair periphery, wherein 1.015 1.030 times of a diameter of peripheral gage of wire of the central hair, the central hair of a diameter of peripheral 1.015 1.030 times of silk diameter is formed by 2 or 3 root wire twistings.
Description
Technical field
Field of welding material is the utility model is related to, particularly a kind of cable formula welding wire.
Background technology
Cable formula welding wire is also known as stranded electrode, sees a kind of multi-strand stranded welding wires of patent document 200910027603.X, is to use
More medicine cores or solid welding wire rotation are twisted, and what application was most at present is 7 strands, as shown in Figure 1 and Figure 2, wherein a root wire
2 are referred to as central hair, and positioned at centre, remaining 6 root wire 1 (being referred to as peripheral silk) surrounds central hair, and middle cored welding wire and peripheral welding wire are straight
Footpath is equal, and cable shape formula major diameter welding wire is illustrated through twisted formed, i.e., respectively by diameter of phi 1.0mm and, Φ 1.2mm, Φ 1.6, Φ 2
With Φ 2.4 welding wire be twisted into diameter of phi 3.0, Φ 3.6, Φ 4.8, Φ 6, Φ 7.2 cable formula welding wire.Carried out using this welding wire
Automatically or semi-automatically arc welding have energy-efficient (deposition efficiency is high, welding penetration is big, saves electric energy), welding equipment it is simple,
Outstanding advantages of easy to operate and joint quality is reliable and stable, great application value.
The cable shape formula formed using an existing this middle cored welding wire six roots of sensation periphery welding wire equal by diameter is found
Major diameter welding wire, welding process China and foreign countries weld all around silk burn-off rate be more than middle cored welding wire burn-off rate, this phenomenon with often
The theory analysis of rule contradicts.1st, theoretical according to electric arc, under conditions of direct current, electric arc has the function that to gather to center,
The current density that six roots of sensation periphery welding wire forms six rotating the arcs should be less than the current density of middle cored welding wire, therefore, center weldering
The burn-off rate of silk should be more than the burn-off rate of peripheral welding wire；2nd, in terms of radiating condition, there are six rotations around middle cored welding wire
High-temperature electric arc, and around peripheral welding wire be protective gas (gas shield welding) or slag (submerged-arc welding), it is clear that peripheral welding wire will be to
Periphery radiating, therefore, the burn-off rate of middle cored welding wire should be more than the burn-off rate of peripheral welding wire.
Therefore it provides one kind, in arc welding process, the cable formula welding wire that middle cored welding wire can synchronously melt with peripheral welding wire is
Urgent problem to be solved.
Utility model content
In view of this, main purpose of the present utility model is, overcomes above-mentioned existing for existing cable shape formula major diameter welding wire
Defect, and a kind of cable formula welding wire is provided, technical problem to be solved is to make it in arc welding process, middle cored welding wire and periphery
Welding wire can synchronously melt.
The utility model provides a kind of cable formula welding wire, including central hair and curls up in the peripheral silk of central hair periphery, its
In, 1.015-1.030 times of a diameter of peripheral gage of wire of the central hair.
In such scheme, the central hair of a diameter of peripheral 1.015-1.030 times of silk diameter is by 2 or 3 root wires
Twisting forms.
In such scheme, the central hair that is made up of 2 root wires is two cable formula central hairs, in two cable formulas
The filament diameter of heart silk is 0.5 times of central hair diameter, and lead angle is 65-70 degree.
In such scheme, the central hair that is made up of 3 root wires is three cable formula central hairs, in three cable formulas
The filament diameter of heart silk is 0.464 times of central hair diameter, and lead angle is 56-60 degree.
The cable formula welding wire of the utility model cable formula welding wire single, central silk equal with peripheral silk diameter with existing diameter
Compared to clear advantage and beneficial effect.By above-mentioned technical proposal, cable formula welding wire of the invention in arc welding process,
Central hair fusing synchronous with peripheral silk, makes welding process more stable.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, and in order to allow above and other purpose of the present utility model, feature
It can be become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, described in detail as follows.
