[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] In the description of this utility model, "multiple" means two or more; "greater than," "less than," and "exceeding" are understood to exclude the stated number; "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0020] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components.

[0022] Reference Figures 1-4 The present invention provides a metal strip wire, including a strip wire 10 and at least one cold spray welding layer 20 disposed on the strip wire 10, the cold spray welding layer 20 being used for welding with external devices.

[0023] In this invention, the strip 10 is preferably made of aluminum substrate. Pre-treatment of the area on the strip 10 that needs to be externally welded can improve the reliability of the bond between the strip 10 and the cold spray welding layer 20. The pre-treatment can be grinding, etc., to increase the roughness of the area on the strip 10 to be cold sprayed, thereby improving the adhesion of the cold spray welding layer 20. Furthermore, the pre-treatment area can be the entire surface area of ​​the strip 10, or only the local area to which the cold spray welding layer 20 is attached. Cold spraying is performed on the pre-treated area using cold spraying equipment, so that at least one cold spray welding layer 20 is attached to the strip 10. The cold spray welding layer 20 enables the strip 10 to be welded to external devices.
