Abstract
The invention relates to an improved welding rod, which comprises a core wire and a cover, wherein the cover covers on the core wire; a cross section of the core wire is in a regular pentagon shape or a regular hexagon shape; at least four circular holes are arranged in the cover; the diameter of each circular hole is 1mm; the circular holes are uniformly distributed along the circumference of the end face of the cover. According to the improved welding rod, through changing the shape of the cross section of the core wire, a contact area of the wire core and the cover is increased, and the combustion is quicker and more sufficient; meanwhile, the circular holes are arranged in the cover, the accumulated increased internal pressure is relieved, and the occurrence of the phenomenon of splashing or air holes is reduced.
Description
Technical field
The present invention relates to a kind of welding rod, relate in particular to and a kind ofly can light fast, reduce and splash or modified welding rod that the pore phenomenon occurs.
Background technology
Welding rod is exactly the consumable electrode for SMAW that scribbles coating, and it is dimerous by coating and core wire.The chamfering of 45 ° of left and right is arranged at welding rod front end coating, and this is for the ease of striking.At afterbody, one section naked core wire is arranged, accounts for welding rod overall length 1/16, be convenient to soldering turret clamp and be conducive to the conduction.
Core wire in the welding rod of prior art is cylindric, and core wire is coated with one deck coating, and the core wire of this structure shape and coating contact area are little, are not easy to light fast; Simultaneously, due to after welding rod is heated, after fusing and vaporization occur the core wire in it, interior pressure raises rapidly, easily produces and splashes or pore.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide a kind of and can light fast, reduced and splash or modified welding rod that the pore phenomenon occurs.
The present invention is achieved through the following technical solutions:
A kind of modified welding rod, comprise core wire and coating, and described coating is coated on core wire, and the cross section of described core wire is polygon, is provided with at least four circular holes in described coating.
Further, described polygon is regular pentagon.
Further, described polygon is regular hexagon.
Further, the diameter of described circular hole is 1mm, and described circular hole circumferentially is uniformly distributed along the end face of coating.
Further, the length of this welding rod is 250-450mm.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by changing the cross sectional shape of core wire, increases its contact area with coating, and burning is abundant more fast; In coating, be provided with circular hole simultaneously, alleviate the interior pressure of gathering increase, reduce and splash or the generation of pore phenomenon.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of modified welding rod of the present invention.
The specific embodiment
In order to make purpose 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, the structural representation that Fig. 1 is a kind of modified welding rod of the present invention.
Described a kind of modified welding rod, the length of this welding rod is 250-450mm, and it comprises core wire 1 and coating 2, and described coating 2 is coated on core wire 1, and the cross section of described core wire 1 is polygon, and described polygon is regular pentagon or regular hexagon.The present invention, by changing the cross sectional shape of core wire 1, increases its contact area with coating 2, and burning is abundant more fast.
Be provided with at least four circular holes 3 in described coating 2, the diameter of described circular hole 3 is 1mm, and described circular hole 3 circumferentially is uniformly distributed along the end face of coating 2.The present invention is by being provided with circular hole 3 in coating 2, gathers the interior pressure of increase in the time of can effectively alleviating burning, reduces and splashes or the generation of pore phenomenon.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications 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.
