Abstract
The utility model relates to an anti-splashing welding rod which comprises a core wire and a coating. The coating wraps the core wire which is provided with a semicircular protruding face, and the coating is provided with a semicircular opening. A triangular opening is changed to be the semicircular opening, inside pressure in the coating can be fully released, and splashing is prevented; the semicircular protruding face enables the contact area of the core wire and the coating to be large, and combustion is quicker and more adequate.
Description
Technical field
The utility model relates to a kind of welding rod, relates in particular to a kind of anti-welding rod that splashes.
Background technology
Carbon is the main alloy element in steel, and when phosphorus content increases, intensity, the hardness of steel obviously improve, and Plasticity Decreasing.In welding process, carbon plays certain deoxidation, under high arc temperature effect with oxygen generation chemical combination, generate carbon monoxide and carbon dioxide, arc region and molten bath surrounding air are got rid of, prevent the harmful effect that airborne oxygen, nitrogen pernicious gas produce molten bath, the content of oxygen and nitrogen in minimizing weld metal.If phosphorus content is too high, reduction is violent, can cause larger splashing and pore.Consider that carbon is on the hardenability of steel and the impact on crack sensitivity increase thereof, the phosphorus content of low carbon steel welding core is generally 0. 1%.
Welding rod consists of core wire and coating two parts, welding rod be outside metal core wire by coating (coating) evenly, centripetally extrusion on core wire.Existing welding rod, easily stress is concentrated and in welding process, is occurred splash phenomena, causes the short-circuit conditions of solder joint and solder joint, affects welding quality.Patent 201020529484.6 discloses a kind of anti-solder stick that splashes, and has really played good release internal pressure, has prevented the effect of splashing, and triangular in shape because of its opening, anti-splash phenomena can not be eliminated completely.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of anti-welding rod that splashes is provided.
The utility model is to be achieved through the following technical solutions:
The anti-welding rod that splashes, comprises core wire and coating, and described coating is coated on core wire, and described core wire is provided with semi-cylindrical hill face, and described coating is provided with semicircle opening.
Further, the quantity of described semi-cylindrical hill face is four, is evenly distributed on core wire.
Further, the diameter of described semi-cylindrical hill face is 1mm, and the diameter of described core wire is 3mm.
Further, the quantity of described semicircle opening is four, is evenly distributed on coating.
Further, the diameter of described semicircle opening is 1mm, and the diameter of described coating is 7mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by triangle open mouth being become to semicircle opening, can fully discharge its internal pressure, prevents from splashing; By semi-cylindrical hill face is set, make core wire and coating contact area large simultaneously, burn more abundant sooner.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anti-welding rod that splashes of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of a kind of anti-welding rod that splashes of the utility model.
Described a kind of anti-welding rod that splashes, comprises core wire 1 and coating 2, and described coating 2 is coated on core wire 1, it is characterized in that, described core wire 1 is provided with semi-cylindrical hill face 3, and described coating 2 is provided with semicircle opening 4.The interior pressure producing after welding rod is heated can discharge automatically, overcomes solder alloy and splashes, thereby avoided the phenomenons such as the easy short circuit of welded product, company's weldering, has improved operating efficiency and product quality.
The quantity of described semi-cylindrical hill face 3 is four, is evenly distributed on core wire 1, and the diameter of described semi-cylindrical hill face 3 is 1mm, and the diameter of described core wire 1 is 3mm.
The quantity of described semicircle opening 4 is four, is evenly distributed on coating 2, and the diameter of described semicircle opening 4 is 1mm, and the diameter of described coating 2 is 7mm.
To sum up, the utility model, by triangle open mouth being become to semicircle opening 4, can fully discharge its internal pressure, prevents from splashing; By semi-cylindrical hill face 3 is set, make core wire 1 and coating 2 contacts area large simultaneously, burn more abundant sooner.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
