[0020] As Figures 1 to 7As shown, a tightly assembled welding wire, which comprises a cylindrical welding rod main structure 1, one end of the welding rod main structure 1 is provided with a spherical splicing stable matching seat 2, which can be used as the splicing matching structure of other welding wire products. The splicing stable matching seat 2 is connected with the welding rod main structure 1 in a detachable manner, which ensures that the overall production and processing cost is lower, and the material of the splicing stable matching seat 2 can be processed to have a hardness and a melting point far greater than that of the welding wire material. This structure can be used alone in use, which is convenient for recycling and reuse. The diameter of the welding rod main structure 1 is smaller than that of the splicing stable matching seat 2, which ensures that the volume of the structure is larger, and has enough matching space when matched with other welding wire products. The left and right sides of the welding rod main structure 1 are respectively provided with a splicing placement matching groove 3 with a circular arc cross section, which can tightly splice different welding wire products together to form an integral structure. The splicing placement matching groove 3 penetrates the lower end of the splicing stable matching seat 2, the splicing placement matching groove 3 penetrates the outer side of the splicing placement matching groove 3, and the projection structure of the intersection position of the splicing placement matching groove 3 and the splicing stable matching seat 2 has a circumference greater than half of the circumference of the cylindrical structure with the same diameter. The matching position has reliable anti-dropping effect, which ensures better tightness during matching, can meet the splicing and matching of welding wire or welding rod products, and can meet the welding of multiple welding materials at the same position. When used, the splicing stable matching seat and the splicing placement matching groove are arranged on the main structure, which can tightly splice two kinds of welding wire products at most, and can make the tightness between different welding wire materials better during matching, which can ensure simultaneous fusion during welding, and can make the uniformity of the mutual fusion of different welding wire materials better, and the welding strength of the welding position during welding is better. When splicing and matching, the space occupied is smaller, and the matching position has a certain anti-dropping effect, which makes the stability during matching more reliable and the safety during welding higher.

[0021] As preferred, the diameter of the splicing stable matching seat 2 is 2 times the diameter of the welding rod main structure 1, which can ensure that the splicing stable matching seat 2 has smaller volume and better convenience in use on the basis of ensuring matching stability, occupies smaller space during matching, and has relatively lower production cost.

[0022] As preferred, the splicing stable matching seat 2 is connected with the welding rod main structure 1 by threaded connection, which makes the production cost lower, and can also be combined by compression fitting, but the production cost is relatively high, and the convenience of recycling and use is relatively poor.

[0023] As preferred, the splicing stable fitting seat 2 is made of high-temperature alloy steel material, so that it has better durability in use, longer service life in use, can be recycled for multiple times, and has lower use cost.

[0024] As preferred, the end of the fitting position of the welding rod main body structure 1 and the splicing stable fitting seat 2 is provided with a spherical sealing combined stable groove, so that the fitting area of the combined position can be larger, and the fitting stability is better.

[0025] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the ordinary technical personnel in the art, without departing from the principle of the present application, under the premise of, can make a number of improvements or replacement, these improvements or replacement also should be considered as the protection scope of the present application.
