Technical Field

[0001] The invention belongs to the field of brazing, in particular to the field of aluminum alloy brazing, and specifically relates to a high-conductivity clamp welding sheet filling auxiliary tool and a use method thereof. Background Art

[0002] The high-conductivity welding clamp is a welding clamp composed of a high-melting-point metal and a low-melting-point solder, see patent CN113909734B. It requires a high-melting-point metal to be set through the welding clamp to form a conductive channel with a certain area. During the welding process, these channel materials do not melt. In the production process, in addition to winding the two materials with each other and extending them into sheets through a calender, the solder can be filled first, and then the metal particles or metal wires can be filled. During the filling process, in order to ensure that the material in the welding clamp is compact, it is necessary to fill the solder first, and then insert the opening rod into the solder to form a hollow channel, and then fill the metal. During the filling process, after the opening rod is pulled out, part of the solder will refill the shell, resulting in the filled metal cannot form a coherent channel, so it is necessary to design a new filling auxiliary tool.

[0009] Or fill the brazing shell with brazing material, and use auxiliary tools to insert them from both sides of the top of the shell from the outside to the inside, until the tapered section of the guide rod is completely pushed out of the brazing shell and stays for a while, then pull the auxiliary tool out in the opposite direction at the same time to bring out the brazing material of the welding shell, fill the two empty grooves pulled out by the auxiliary tool with metal particles or metal wires, and press the brazing shell into a sheet.
