Background

The existing aluminum profile products are limited in extrusion processing size or required in three-dimensional structures, and welding processing is often needed to obtain the required final product shape. In order to improve the efficiency and quality of welding, practitioners have developed many different designs of welding interface positions, which are all intended to improve the yield and efficiency of welding. However, the conventional welding scheme usually considers only a simple design for the matching position of two profiles, mainly aiming at better matching between the welding position and the welding gun. Although the structural design is different, the problems that the heat affected zone is large in the welding process and defects such as air holes and cracks are easy to generate are still difficult to avoid.

Particularly, for 6-series aluminum-magnesium-silicon alloy, because 6-series aluminum alloy has high strength, easy processing and forming and good corrosion resistance, the 6-series aluminum alloy is widely applied to various use scenes, particularly to applications needing welding and forming, such as ship decks, pedestrian bridges and the like. However, since the 6-series aluminum alloy has good heat conductivity, the heat affected zone is easily enlarged during welding, welding energy is wasted, welding efficiency is reduced, and welding defects are generated. Therefore, how to improve the welding effect of the welding interface by carrying out novel structural design on the welding interface is very important.

The conventional welding interface is designed as shown in fig. 1, and mainly leaves a position filled with a melted welding wire as a joint of two profiles. All the strength of the combined part is determined by the combination of the melted welding wire and the base material, and the local heat affected zone is larger and the integral welding quality is difficult to ensure because the area of the part needing to be filled is large and the heat input is large.

Furthermore, if the terms "first" and "second" are used for descriptive purposes only, they are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. Thus, the definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features, and in the description of the invention, "at least" means one or more unless specifically defined otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "assembled", "connected", and "connected", if any, are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; or may be a mechanical connection; the two elements can be directly connected or connected through an intermediate medium, and the two elements can be communicated with each other. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.

In the present application, unless otherwise specified and limited, "a first feature" on "or" under "a second feature may include the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact through another feature therebetween. Also, the first feature "above," "below," and "over" the second feature may include the first feature being directly above and obliquely above the second feature, or simply an elevation where the first feature is at a higher level than the second feature. The first feature being "above", "below" and "beneath" the second feature includes the first feature being directly below or obliquely below the second feature, or merely means that the first feature is at a lower level than the second feature.

The following description will be further made in conjunction with the accompanying drawings of the specification, so that the technical solution and the advantages of the present invention are clearer and clearer.

Therefore, when the combined welding is carried out, most of the directly heated points are at the positions of the auxiliary strips, the volume of the welding interface position needing to be filled is small, and compared with the traditional filling area, the filling area can be reduced by 10% -30%, so that the welding material cost can be saved, the welding time is shortened, and the welding efficiency is improved; and the total contact area of the welding interface is larger, the connection strength is better, the loss of the welding strength can be better compensated, and the strength of the welding position is higher.

In this embodiment, it is preferable that the cavity is a cylindrical cavity, and the auxiliary bar 5 is an auxiliary round bar. Because of the length of part welding material is longer, if there is 10 meters continuous welding such as boats and ships deck, twist reverse easily appearing when production in the auxiliary strip, if adopt special-shaped auxiliary strip to lead to probably appearing the card and dying or fill inhomogeneous condition when putting into welding interface position easily, use the round bar can effectively avoid the material to twist reverse the problem of twisting, guarantee to put into the interface smoothly after the cooperation section bar combination, guarantee to fill the effect. Of course, the specific shape of the cavity and the auxiliary strip can be selected by those skilled in the art according to the actual use situation, such as using a square or a special-shaped auxiliary strip in the case of a short length of welding material, and is not limited to the embodiment.

It should be noted that the outer ends of the bottoms of the first welding position 3 and the second welding position 4 are respectively provided with welding grooves which are matched with each other, and when the first welding position 3 and the second welding position 4 are in butt joint, the two welding grooves form a welding port 6 which is located at the bottom of the cavity.
