Abstract
The invention relates to a welding rod capable of being fully burnt. The welding rod capable of being fully burnt comprises a core wire and a coating layer covering on the surface of the core wire, wherein the section of the core wire is round; the coating layer is provided with blind holes along the axis direction; the section of the blind hole is round; the diameter of the blind hole is 0.8mm; the front end of the core wire is provided with an angle of chamfer; the tail part of the core wire is provided with a clamping section. According to the welding rod capable of being fully burnt, which is disclosed by the invention, due to the fact that the coating layer is provided with blind holes along the axis direction, the contact area between the coating layer and oxygen is enlarged in the burning process, the coating layer can be guaranteed to be fully burnt, defects of more scummings, uneven welding spots and the like after welding due to insufficient burning are avoided, and the welding quality and the attractive effect are improved.
Description
Technical field
the present invention relates to welding technology field, relate in particular to a kind of welding rod of being convenient to sufficient combustion.
Background technology
welding rod is made up of core wire and coating two parts.Welding rod be outside metal core wire by coating (coating) evenly, centripetally extrusion on core wire.Welding rod kind difference, core wire is also different.Core wire is the metal-cored of welding rod, in order to ensure quality and the performance of weld seam, the content of each metallic element in core wire is had to strict regulation, and the particularly content to objectionable impurities (as sulphur, phosphorus etc.), should have strict restriction, is better than mother metal.Core wire composition directly affects composition and the performance of weld metal, so the harmful element in core wire will lack as far as possible.
the defects such as welding rod of the prior art burning is insufficient, easily causes oxidation, and after welding, scum silica frost is more, and solder joint is inhomogeneous, thus make not prison welding solid, affect welding quality and aesthetic property is poor.
Summary of the invention
the present invention, in order to overcome deficiency of the prior art, provides a kind of welding rod of being convenient to sufficient combustion.
the present invention is achieved through the following technical solutions:
be convenient to a welding rod for sufficient combustion, comprise core wire and be coated on the coating layer on core wire surface, the cross section of described core wire is rounded, and described coating layer offers blind hole along axis direction, and the cross section of described blind hole is circular.
as the preferred technical solution of the present invention, the front end of described core wire is provided with chamfering, and the angle of chamfering is 45 degree.
as the preferred technical solution of the present invention, the afterbody of described core wire is provided with gripping section.
as the preferred technical solution of the present invention, described blind hole diameter is 0.8mm.
as the preferred technical solution of the present invention, the length of described core wire is 300-550mm.
as the preferred technical solution of the present invention, the diameter of described core wire is 6mm.
as the preferred technical solution of the present invention, the length of described gripping section is 1/16 of core wire length.
compared with prior art, the invention has the beneficial effects as follows: the present invention is by offering blind hole at the axis direction of coating layer, in combustion process, increase the contact area of coating layer and oxygen, can ensure the abundant burning of coating layer, prevent from, because of insufficient defects such as the rear scum silica frost of welding is more, and solder joint is inhomogeneous that cause of burning, improving quality and the aesthetic of welding.
Brief description of the drawings
fig. 1 is structural representation of the present invention.
in figure: 1-core wire; 2-coating layer; 3-blind hole; 4-chamfering; 5-gripping section.
Detailed description of the invention
in order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
refer to Fig. 1, Fig. 1 is structural representation of the present invention.
described a kind of welding rod of being convenient to sufficient combustion, comprise core wire 1 and be coated on the coating layer 2 on core wire 1 surface, the cross section of described core wire 1 is rounded, and described coating layer 2 offers blind hole 3 along axis direction, the cross section of described blind hole 3 is circular, and described blind hole 3 diameters are 0.8mm.In combustion process, increase the contact area of coating layer and oxygen, can ensure the abundant burning of coating layer, prevent from, because of insufficient defects such as the rear scum silica frost of welding is more, and solder joint is inhomogeneous that cause of burning, improving quality and the aesthetic of welding.
the front end of described core wire 1 is provided with chamfering 4, and the angle of chamfering 4 is 45 degree, is convenient to striking.
the afterbody of described core wire 1 is provided with gripping section 5, be convenient to soldering turret clamp and be conducive to conduction; The length of described gripping section 5 is 1/16 of core wire 1 length, and the length of described core wire 1 is 300-550mm, and the diameter of described core wire 1 is 6mm.
the foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
