Abstract
The invention relates to a welding electrode with a coating, belonging to welding materials for manual electric arc or automatic electric arc continuous welding. The disk type welding rod of the invention is provided with a welding rod ring (1) radially wound on a welding rod mould disk (2), one side or two sides of the welding rod ring (1) are provided with a conductive groove (4), the tail part (3) of the welding rod passes through the welding rod mould disk (2) and is exposed outside, and the disk type welding rod also comprises an end sealing clamp (5) for pressing the whole welding rod ring (1) except the head part (6) of the welding rod. The disk type welding electrode is particularly suitable for noble welding materials such as stainless steel and the like.
Description
The present invention relates to a kind of welding rod with coating, is the manual welding material that electric arc connects or automatic arc welding connects continuously.
The welding rod of existing band coating in the world all is that length is not more than 50 centimetres one one straight short welding rod, and this welding rod has with next major defect: 1. because welding rod length is very short, can not carry out continuous arc welding, more can't weld automatically; 2. because can not continuous welding, welding line joint be a lot, has a strong impact on weldquality; 3. the welder needs often to change welding rod, and welding production efficiency is low; 4. each root bead bar all has the tail end of 4-5 centimeter length can not weld and abandon, and the waste of material rate improves welding cost greater than 15%.
The purpose of this invention is to provide a kind of disk type welding rod that turns to the band coating of plate-like, the length of its welding rod can decide according to the needs of fusion length, generally speaking can be greater than more than 5 meters, device in when welding by welding gun, the disc type welding rod can slowly rotate under manual or electronic effect, carries out the continuous electric arc welding.Thereby in the many disadvantages that fundamentally overcomes existing welding rod.
Invention is achieved in that and radially is wound with electrode ring (1) on welding rod dish (2), the one or both sides of electrode ring (1) offer conductive trough (4), welding rod afterbody (3) passes the welding rod mould and is exposed, and also comprises the end envelope card (5) of the whole electrode ring (1) that compresses except that welding rod head (6).
Also having electrode ring (1) is that welding rod coiling by sub-thread band coating forms.
In more detail: at first prepared the bigger electrode coating coating of viscosity, go out the welding rod of the band coating of all lengths with this coating material production, electrode size can be controlled at below the diameter 2.5mm, the core wire material can be the needed metal material of each weld seam, as ordinary carbon steel, stainless steels etc. are wound on this very long welding rod on the preprepared welding rod dish to welding rod by the drum machine then.Again according to the size of welding rod welding current, offer the conductive trough of certain width in the one or both sides of the good electrode ring of coiling after coiling finishes, be packaged into box at last, promptly get disk type welding rod.
This disc type welding rod has four advantages:
1, can carry out the manual arc continuous welding fully, also can be used as automatic arc welding and connect material, improve welding quality comprehensively and enhance productivity.
2, do not have welding line joint, increased substantially weldquality, reduced the percent defective of welding, reduced welder's solder technology difficulty.
3 compare with the cost of existing welding rod, and the disc type welding rod can be saved cost more than 15%.
4, disc type welding rod compact appearance, beautiful, easy to carry.
Narration below by embodiment and accompanying drawing thereof describes the present invention in detail.
Accompanying drawing: the disk type welding rod structure chart, wherein:
(1) electrode ring (2) welding rod mould (3) welding rod afterbody
(4) conductive trough (5) end envelope card (6) welding rod head
The structure of disk type welding rod shown in the drawings is described as follows:
Welding rod figure (1) has the welding rod of band coating radially to be wound on welding rod mould (2) by the long energy brake forming of sub-thread upward to form, and the material of curved bar mould can be plastics, bakelite or thin metal material.Welding afterbody (3) does not have coating, and the open slot that passes welding rod mould bottom is exposed, and can switch on, and plays and shares the partly conduction of welding current.Conductive trough (4) is offered in the one or both sides of electrode ring, and the degree of depth of conductive trough is slightly larger than coating thickness.Welding current mainly is to rely on conductive trough to conduct to core wire, and the width of conductive trough decides according to the size of electrode size.For example the straight carbon steel electrode size is that the width of its conductive trough of 1.6mm can be designed to about 2mm.The quantity of conductive trough can be provided with 6 generally speaking, also can carry out specific design according to the size of welding current.
End envelope card (5) can move radially along the end sealing groove of welding rod mould baffle plate, can compress whole electrode ring all the time, only allows welding rod head (6) be exposed.End envelope card also can be designed to the outer ring Zhou Yidong along the welding rod mould.
According to the quantity of electrode ring, disk type welding rod can be divided into individual layer again, bilayer or multilayer disk type welding rod.
Because all there is baffle plate on welding rod mould both sides, so the coiling of electrode ring is very convenient, conductive trough just can mill with the conventional mechanical processing method to be made, so the production of disk type welding rod enforcement is easy.
Claims (2)
1, a kind of disk type welding rod, it is characterized in that, on welding rod mould (2), radially be wound with electrode ring (1), the one or both sides of electrode ring (1) offer conductive trough (4), welding rod afterbody (3) passes welding rod mould (2) and is exposed, and also comprises the end envelope card (5) of the whole electrode ring (1) that compresses except that welding rod head (6).
2, according to the described disk type welding rod of claim 1, it is characterized in that, electrode ring (1) be by the welding rod of sub-thread band coating radially coiling form.
