[0002] Tin soldering sheet is a kind of welding material made of tin (Sn) and other metal (usually lead Pb or silver Ag) alloy, mainly used for the welding of metal parts. Tin soldering sheet is used to melt and fill into the connecting part after heating, and solidifies after cooling, thereby forming the welding of metal parts. The advantage of tin soldering is its good electrical conductivity, low melting point and strong adaptability.

[0003] At present, commonly used tin soldering sheet is directly exposed to air, and tin soldering sheet is easy to oxidize in air, forming an oxide film. This oxide film will affect the quality of metal part welding, resulting in poor welding. When the welding of metal parts only needs to melt and fill one fourth or one eighth of the entire tin soldering sheet into the connecting part, a cutting tool is needed to cut the tin soldering sheet. The cutting of tin soldering sheet by cutting tool is not only low in efficiency, but also not simple and convenient.
