Welding methods for difficult-to-weld hot materials and aluminum.

Very high fastening strength in one step! Fastening different materials that are difficult to weld without pre-drilling. No heat is generated, and it can be easily used by anyone.

"RIVSET" is a high-strength, reliable self-piercing rivet. It easily mechanically joins different types of materials without the need for a pilot hole. It is also possible to fasten three or more materials. This product penetrates the upper base material and expands at the tip due to the shape of the die within the lower base material. By using self-piercing rivets, fastening can be easily achieved for thin sheets that are difficult to weld, materials with different properties, and dissimilar materials. Examples include combinations with a high ratio of total plate thickness to the thinnest plate thickness, aluminum 5000 x aluminum 6000, hot press materials, and plate assemblies that require multiple welds at spots. 【Features】 ■ Fastening of dissimilar metals ■ No need for pilot hole processing ■ Environmentally friendly construction method ■ Cost reduction ■ High static and dynamic strength ■ Ideal for combinations of various materials, including high-tensile steel sheets.
