Compared with prior art, the advantage of the invention is that：
1st, the welding wire that the present invention can be after strand is forged, and operating efficiency is high, can eliminate strand welding wire ring,
Planted agent's force phenomenon, so as to obtain preferable strand welding wire surface state, and the linearity of strand welding wire can be improved, finally obtained
Forging strand welding wire has following excellent properties：
（1）, electric conductivity
On the basis of all advantages of rope form strand welding wire are kept, surface forging is carried out, welding wire surface is formed the face of cylinder
Form, the contact surface with ignition tip are longitudinal solid line, with the formalness of traditional monofilament and essentially the same using configuration custom,
Add the strand welding wire good characteristics that monofilament does not possess again simultaneously；
（2）, frictional force
Strand welding wire after surface forging, internal structure keep strand welding wire feature itself, outside original helical groove portion
Lease making crosses swaging deformation, and filling and leading up groove makes formalness be in cylinder planar, surface flat smooth as conventional monofilament, significantly
Reduce the frictional force between welding wire and electric installation, improve the service life of each auxiliary in wire feed path, and with traditional weldering
The versatility for connecing equipment and auxiliary is high；
（3）, welding process gas shield performance
Forge strand welding wire surface form flat smooth as conventional monofilament of completion, the conveying of welding process gas and guarantor
Shield occurs than more complete in the absence of the Welding Problems of new life；
（4）, surface manufacture process control difficulty
It is to carry out forging processing again after the completion of rope form strand due to forging strand welding wire, passes through high-frequency and high intensity
Process is forged, shaping is forged under the requirement of integral diameter, the diameter and configuration of surface requirement to a certain monofilament can be by forging
The secondary repairing of process, monofilament displacement and impact endurance test shock of the slag inclusion during forging easily keep good cleaning；
（5）, welding process molten bath control difficulty
Rotating the arc control is made electric arc height in the range of gage of wire circular arc in strand welding wire welding process after forging
Degree is concentrated, and has both maintained the advantages that strand welding wire welds required rotating the arc melting bath stirring, and control fusion penetration molten wide very well
Requirement, easily realize perfect welding process；
（6）, manufacture coiling gap to using process influence
Strand welding wire after forging into helical groove, solves rope form diameter extrusion packing in the case where keeping strand welding wire characteristic
The defects of rope form strand welding wire manufacturing process of having determined；
（7）, internal memory stress influence
Strand welding wire after forging, internal stress have substantially eliminated, from being fabricated onto the process used and conventional monofilament
It is basically identical；
（8）, it is twisted after string diameter control error precision
The trueness error for forging strand welding wire controls a step to be easier to realize by forging footpath mould in the fabrication process,
And forged by the high-frequency and high intensity of manufacturing process, the very small string diameter shape having substantially no effect on during storage of residual stress
Become；
（9）, welding wire manufacturing process and production cost control
Forge strand welding wire quality control and concentrate on the final step forged, enormously simplify production procedure, monofilament is drawn
Range request reduction was pulled out, each monofilament lay pitch of strand process and string diameter is required to reduce, significantly improving production efficiency, saves manufacture
Cost.
2nd, the present invention uses planetary gear construction, and transmission power is big, and hammering deformation can be significantly carried out to strand welding wire, and
And deflection is big, better than the swager of traditional cylindrical roller structure；
3rd, the present invention can be lubricated using planetary gear construction using lubricating grease to structure, will not be to strand welding wire
Surface quality is had an impact, and because strand welding wire surface is not smeared with greasy dirt, and the swager of traditional cylindrical roller structure is being forged
Oil stain, which is had, during beating is splashed to strand welding wire surface.
