Description

A kind of novel copper arc welding electrode

Technical field

The utility model relates to copper arc welding electrode technical field, specially a kind of novel copper arc welding electrode.

Background technique

Copper arc welding electrode refers to the wlding using copper and copper alloy, is applicable to oxy-acetylene, TIG, MIG welding, is widely used in The manufacturing industry such as automobile, steamer, electrical.When carrying out actual welding operation, most of weld seams are all that linearly, welding operation is very Simply, but when being welded to the weld seam with special angle, when being welded using two linear copper arc welding electrodes, no It can guarantee the welding effect that weld seam bending is pointed out, it can be by the intensity of low welding.And copper product has good thermal conductivity, meeting Quickly heat is conducted, it is heated not enough uniformly so as to cause brazing core, to reduce the effect of welding.

Utility model content

The purpose of this utility model is to provide a kind of novel copper arc welding electrode, has convenient for bending and improve the excellent of welding effect Point solves the problems, such as to be not easy to bending and welding efficiency is low.

To achieve the above object, the utility model provides the following technical solutions: a kind of novel copper arc welding electrode, including brazing core, Bending slot and groove, brazing core both ends are symmetrically fixed with striking block, and two striking block surfaces are coated with striking painting Layer, brazing core upper surface open up fluted, and brazing core upper surface is fitted with coating, and the brazing core is together with coating two sides Outer wall symmetrically offers the bending slot being equally spaced.

Preferably, brazing core lower surface uses V-type inclined design, and striking block diameter is less than the diameter of brazing core.

Preferably, the coating is partly wrapped in brazing wicking surface, and inside grooves are filled with coating.

Preferably, the bending slot inner wall angle of brazing core two sides distribution is 90 degree, and is located at the folding of brazing core two sides Curved groove corresponds to each other.

Compared with prior art, the beneficial effects of the utility model are as follows:

1, the utility model has been achieved the effect that improve brazing core inner temperature, be located at recessed by setting coating and groove Coating inside slot can release heat after combustion, so that conduction increases the internal temperature of brazing core, accelerate to brazing core inner The thawing speed of brazing core promotes the welding effect of brazing core.

2, the utility model has achieved the effect that, convenient for bending brazing core, staff can basis by setting bending slot Brazing core is bent by bending slot, is bonded the angle of brazing core with specific weld seam, avoids by the case where actual use When the weld seam to special angle welds, needs to be fitted in inside weld seam using two linear copper arc welding electrodes, cause The effect of the vertex welding defective tightness of weld seam.
