"Friction welding" is a processing method that achieves bonding by generating friction heat through the contact and pressure of metal parts against each other, causing the materials to heat up and compressively deform strongly due to the applied pressure, bringing the bonding surfaces close together. 【Examples of processing using friction welding】 From mechanical joining of stainless steel components to friction welding ■ Reduction in the number of parts: from 6 parts (7 points) to 2 parts (2 points) ■ Improvement in quality: tensile strength increased by 23%, torsional strength increased by 12% ■ Reduction in processes: reduction of assembly tasks such as bolt tightening ■ Weight reduction of products: reduction in weight of slit collar (70g) and screws (20g) 　　　　　　　　　　↓ Achieved a 28% cost reduction along with increased strength and weight reduction! *For more details, please refer to the PDF document or feel free to contact us.

"Friction Stir Welding" is a technique that joins base materials by rubbing them together at high speed, softening the materials due to the friction heat generated while simultaneously applying pressure to achieve the joint. It eliminates the need for consumables such as welding rods and flux, reducing labor costs. No heat source other than friction heat is required, resulting in high energy efficiency. Additionally, it allows for a reduction in material and processing costs compared to machining from solid blocks, and by minimizing the weight of the material, it can improve yield rates. [Features] ■ Achieves joint strength equivalent to the base material through individual jointing ■ Enables joining of dissimilar metals (e.g., copper + aluminum, aluminum + stainless steel, etc.) ■ Joint conditions can be numerically managed, ensuring reproducibility and stable quality ■ Environmentally friendly ■ Cost reduction is possible *For more details, please refer to the PDF document or feel free to contact us.
