Embodiment 1

[0035] refer to figure 1 with Figure 4 Shown: a film for welding, including a metal layer 1, a solder layer 2, and a viscous adhesive layer 3, the outer surface of the metal layer 1 is covered with a solder layer 2, and the outer surface of the solder layer 2 is glued with welding activity sticky glue layer3.

[0036] The welding film 5 is a strip-shaped rubber strip, the length is not limited, and the upper and lower sides of the welding film 5 are sticky.

[0037] The metal layer 1 is made of metal copper.

[0038] The welding film 5 is wound on a fixing base 6 .

Embodiment 2

[0040] refer to figure 1 with image 3 Shown: A welding method comprising the following steps:

[0041] S1. Making the welding film 5: using a cutting device to cut the metal layer 1 of the required size; coating or plating the surface of the metal layer 1 with a solder layer 2; then coating or plating the surface of the solder layer 2 with soldering properties The active adhesive adhesive layer 3 is finally pasted with a release paper 7 on the outer surface of the adhesive adhesive layer 3; the welding film 5 is a laminar film.

[0042] S2. Punch the welding film 5 into a row of holes in units of 1cm*1cm. The film can be broken or divided into small pieces according to the size of the weldment. The upper and lower sides of the welding film 5 are sticky, and it is sandwiched between two welding metal 4 in the space between, bonded and fixed;

[0043] S3. Melt the welding film 5 at 115°C-1250°C until it is fixed by welding.

Embodiment 3

[0045] Refer to Figure l and figure 2 Shown: the application of the welding film 5 in the fan welding process in the main computer case:

[0046] The welding film includes a metal layer 1 , a solder layer 2 , and a viscous adhesive layer 3 , the metal layer 1 is attached with the solder layer 2 , and the solder layer 2 is adhered with the viscous adhesive layer 3 . The welding film 5 is a strip-shaped rubber strip, the length is not limited, and the upper and lower sides of the welding film 5 are sticky. The metal layer 1 is made of metal copper. The welding film 5 has a width of 5 cm and a thickness of 15 mm. The welding film 5 is wound on a fixing base 6 .

[0047] The operation of welding the fan and the computer case with the welding film of the above structure:

[0048] First, use a cutting device to cut off the required length of welding film 5 from the fixed seat, and its size is similar to the size of the fan welding surface; then, clamp the welding film 5 in the ga...

Abstract

The invention discloses a glue piece for welding. The glue piece comprises a metal layer, a welding flux layer and a viscous glue layer, the welding flux layer is attached to the outer surface of the metal layer, and the viscous glue layer adheres to the outer surface of the welding flux layer. A brazing method includes the following steps that (1) the glue piece for welding is manufactured; (2) the glue piece for welding is clamped between two workpieces to be bonded and fixed; and (3) the glue piece for welding is melted until the workpieces are welded and fixed. The glue piece for welding has the two-sided viscous glue layer and can bond and fix the workpieces to be welded, the welding position is accurate, the effect is good, a welding method is convenient, rapid and time and effort saving, and the glue piece for welding can be manufactured into different sizes, made of different materials and widely applied to effective welding of various metal or non-metallic materials. Compared with weld-aid pastes, the glue piece has the advantages that the using process is environment-friendly, an operation table board and the workpieces are not polluted, the glue piece is odorless, the quality guarantee period is long, and the storage condition is not strictly limited.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding method, and also to a welding material and its application. Background technique [0002] In the traditional welding process, solder paste or welding liquid is usually applied to the space between the welded metals, and then heated and melted to weld and fix the welded metals. Soldering paste is a paste-like chemical substance that plays two main roles in the welding process: "removing oxides" and "reducing the surface tension of the material to be welded". It is widely used in clock instruments, precision components, medical equipment, and stainless steel crafts , tableware, mobile communications, digital products, air conditioners and refrigerator refrigeration equipment, glasses, knives, radiators, and various types of PCB boards and BGA solder balls. The soldering paste is in a paste-like amorphous state, and its dosage is brought by soldering A certain amount of inconvenien...
