Steel joining method for thick and thin plates (e.g., 3mm + 1mm)

Very high fastening strength with 1-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 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 within the lower base material due to the shape of the die. 2. In the context of CO2 reduction, the fastening method RIVCLINCH, which uses only air as a power source, generates no heat and does not use auxiliary materials like rivets, relies on plastic deformation. By applying multiple impacts, it can achieve comparable shear strength to spot welding or 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 access from one side, and it is also possible to fasten dissimilar materials or use adhesives in conjunction.
