Embodiment Construction

[0012] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings of the embodiments.

[0013] Such as figure 1 As shown, an alloy welding wire of the present invention includes a welding wire body 1 whose cross-section is quadrilateral, wherein the quadrilateral is formed by connecting four inwardly concave arcs end to end. By designing the cross-section of the welding wire as a quadrilateral with each side sunken inward, that is, a quadrilateral with sharp corners, the problem that the welding wire is easy to roll is effectively avoided. The probability of problems such as arc striking and arc breaking can ensure the welding effect very well. Preferably, such as figure 2 As shown,...

Abstract

The invention relates to a welding wire, and particularly discloses an alloy welding wire, which comprises a welding wire body, wherein the cross section of the welding wire body is a quadrangle which is formed by connecting four inwards-sunken circular arcs end to end. According to the alloy welding wire with the structure, the cross section of the welding wire is designed into the quadrangle with inwards-sunken sides, i.e. a quadrangle with sharp corners, so that the problem of high rolling rate of the welding wire is effectively solved; in addition, due to the existence of the sharp corners, the probability of occurrence of the problems of difficulty in arc striking, arc breaking and the like during welding is also reduced, and welding effects are well ensured.

Description

technical field [0001] The invention relates to a welding wire, especially an alloy welding wire. Background technique [0002] When welding, it is used as a filler metal or as a conductive wire welding material at the same time. The cross-section of the existing welding wire is generally circular and will roll, which is easy to bring confusion to the work site. [0003] Invention CN201970025U discloses an alloy welding wire with a square cross-section, which solves the problem that the welding wire is easy to roll, but because the cross-section line is too rigid, it brings the problem that it is not easy to start the arc or even break the arc during welding, which greatly improves the affect production efficiency. Contents of the invention [0004] In view of the above defects in the prior art, the present invention provides an alloy welding wire, which not only ensures its own strength and toughness, but also solves the problem that the welding wire is easy to roll, and...
