Abstract

The utility model relates to a welding wire and especially relates to an alloy welding wire comprising a welding wire body. A cross section of the welding wire body is quadrangle; and four inwardly recessed arcs are connected in an end to end way to form the quadrangle. With the above structure, the cross section of the welding wire is designed into a quadrangle with four inwardly recessed sides, namely into a quadrangle with a closed angle, so rolling of the weld joint can be prevented; and with the closed angle, problems of arc ignition and broken arc can be avoided during welding, so welding effect can be guaranteed.

Description

A kind of alloy welding wire

Technical field

The utility model relates to a kind of welding wire, particularly a kind of alloy welding wire.

Background technology

When welding, as the welded wire material of filling metal or the use of conduct conduction simultaneously, the cross section of existing welding wire is generally circle, can roll, and easily brings confusion to working site.

Utility model CN 201970025 U have announced a kind of alloy welding wire, the cross section of this welding wire is square, thereby solve the problem that welding wire easily rolls, but brought welding during because cross section lines are too stiff, be difficult for the even easily problem of current interruption of striking, greatly affected production efficiency.

Utility model content

For above-mentioned defect of the prior art, the utility model provides a kind of alloy welding wire, and this welding wire has not only ensured self intensity, and toughness has also solved the problem that welding wire easily rolls, and has avoided being difficult for the consequence of striking, easy current interruption simultaneously, has ensured welding efficiency.

A kind of alloy welding wire described in the utility model; Comprise welding wire body, the cross section of described welding wire body is quadrangle, and wherein, quadrangle is by four end to end formation of the circular arc caving inward.

Preferably, in described quadrangle, the joint on every two limits is semi arch and joins.

Preferably, described this external surface of welding wire is coated with olive oil reservoir.

Adopt after said structure, by the cross section of welding wire is designed to the quadrangle that every limit caves inward, it is angular quadrangle, the problem of effectively having avoided welding wire easily to roll, while is due to the existence of wedge angle, in the time of welding, also reduce to be difficult for the probability that the problem such as striking, current interruption occurs, ensured admirably welding effect; Be set to semi arch by the joint on every two limits in quadrangle and join, ensured the intensity of welding wire, in the processes such as carrying, be difficult for causing local loss, guaranteed the stability of welding current in welding process; By at the coated olive oil reservoir of welding wire outer surface, play lubricant effect, effectively improve Wire Performance.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of joint, two limits in the utility model quadrangular cross section.

Detailed description of the invention

In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, a kind of alloy welding wire of the present utility model; Comprise welding wire body 1, the cross section of described welding wire body 1 is quadrangle, and wherein, quadrangle is by four end to end formation of the circular arc caving inward.By the cross section of welding wire is designed to the quadrangle that every limit caves inward, it is angular quadrangle, the problem of effectively having avoided welding wire easily to roll, while is due to the existence of wedge angle, in the time of welding, also reduce to be difficult for the probability that the problem such as striking, current interruption occurs, ensured admirably welding effect.

Preferably, as shown in Figure 2, in described quadrangle, the joint on every two limits is semi arch and joins, and has ensured the intensity of welding wire, is difficult for causing local loss in the processes such as carrying, has guaranteed the stability of welding current in welding process.

Preferably, as shown in Figures 1 and 2, this external 1 surface of described welding wire is coated with olive oil reservoir, plays lubricant effect, has effectively improved Wire Performance.

The above; it is only detailed description of the invention of the present utility model; protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
