Steel joining methods for thick plates with a large thickness-to-width ratio and thin plates.
Very high fastening strength with just one step! Fastening different thicknesses of iron that are difficult to weld without pre-drilling. No heat is generated, and it can be easily used by anyone.
Generally, it is said that thick plates and thin plates with a large thickness-to-width ratio are difficult to weld. When the ratio of thin plates to the total plate thickness is high, the difficulty of welding increases. We will introduce a method that allows for easy fastening even under such conditions. 1. 'RIVSET' is a high-strength, reliable self-piercing rivet. It mechanically joins different types of materials easily without the need for a pilot hole. It is also possible to fasten more than three 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. 2. In the context of the need for CO2 reduction, the fastening method RIVCLINCH, which uses only air as a power source, does not generate heat and does not use auxiliary materials such as rivets, relies on plastic deformation. By applying multiple points, it can achieve comparable shear strength to spot welding and SPR. 3. 'RIVTAC' allows for high-speed fastening of high-strength materials without the need for a pilot hole. It can be used for profile structures with one-sided access fastening and is compatible with fastening dissimilar materials and the use of adhesives.
