Abstract
The utility model relates to a welding electrode. The welding electrode comprises a welding core and a coating layer covering the welding core; the cross section of the welding electrode is provided with a round structure, of which the diameter is 4 mm to 6 mm; and the length of the welding electrode is 250 mm to 450 mm. The welding electrode has the advantages of high temperature resistance, high oxidation resistance, little scum, high weldability, high fluidity, even, bright and plump welding spots, and the like.
Description
[technical field]
The utility model relates to a kind of welding rod, is specifically related to a kind of improvement of welding rod structure, belongs to welding technology field.
[background technology]
Common welding rod is made of core wire and coating two parts.Welding rod be outside the metal core wire with coating evenly, centripetally extrusion on core wire.The difference of welding rod kind, core wire are also different.Core wire is the metal-cored of welding rod, for quality and the performance that guarantees weld seam, the content of each metallic element in the core wire is all had strict regulation, particularly to the content of objectionable impurities (as sulphur, phosphorus etc.), strict restriction should be arranged.Therefore, the core wire composition directly affects the composition and the performance of weld metal, so the harmful element in the core wire will lack as far as possible.
Defectives such as and at present, common welding rod is the test that is unable to bear high temperature more than 300 ℃, causes oxidation easily, and welding back scum silica frost is more, and solder joint is inhomogeneous, thus make not prison welding solid, influence welding quality and aesthetic property is relatively poor.
Therefore, for avoiding above-mentioned technical problem, the necessary more reasonably welding rod of a kind of structure that provides is to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of energy high temperature resistant, anti-oxidant strong welding rod.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of welding rod, and it comprises a core wire and is coated on coating layer on the core wire, the rounded structure in the cross section of this welding rod, its diameter is 4～6mm, the length of this welding rod is 250～450mm.
Welding rod of the present utility model also can be set to: it further comprises the clamping part that is formed by core wire.
Compared with prior art, the utlity model has following beneficial effect: the core wire of welding rod of the present utility model can bear higher temperature (300 ℃～450 ℃), and non-oxidizability is strong, scum silica frost is few, solderability and good fluidity, simultaneously, even, the light, full of solder joint.
[description of drawings]
Fig. 1 is the sectional view of welding rod of the present utility model.
Fig. 2 is the side view of welding rod of the present utility model.
[specific embodiment]
See also Fig. 1 and shown in Figure 2, the utility model is a kind of welding rod, and it comprises a core wire 1 and is coated on coating layer 2 on the core wire 1, the rounded structure in the cross section of this welding rod, and its diameter is 4～6mm, the length of this welding rod is 250～450mm.Wherein, the diameter of described core wire 1 is not less than 2/3 of whole piece welding rod diameter, thereby makes core wire 1 can bear higher temperature (300 ℃～450 ℃).The concrete composition of described core wire 1 and percentage by weight are respectively tin 47～57%, zinc 41～51%, aluminium 1～6%, and the harmful element of described core wire 1 is less, thereby make core wire 1 can bear high-temperature soldering more.One end of described core wire 1 extends coating layer 2, thereby forms a clamping part 11, and described clamping part 11 accounts for 1/16 of whole piece welding rod length, by these clamping part 11 soldered pincers (not shown) clampings this welding rod welding is used.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
