How Does This Metal Zipper Work?

How Friction Stir Welding (FSW) Creates a Perfect Seal Think of it less like gluing two things together and more like kneading two separate pieces of dough until they become one inseparable lump. This happens in four key stages: 1. Plunging & Intense Friction ⚙️ First, a rotating tool, made of a material much harder than the aluminum being welded, is slowly plunged into the joint between the two parts (e.g., the liquid cooling plate and its cover). The tool's high-speed rotation generates immense friction, which in turn creates intense, localized heat. 2. Plasticization (Softening, Not Melting) 🔥 This is the most critical step. The heat generated by friction brings the metal to a "plasticized" state. This means it becomes soft and malleable like clay, but it never reaches its melting point. This is why FSW is called a "solid-state" process. 3. Mechanical Stirring & Forging 🦾 As the rotating tool moves forward along the seam, its specially designed pin stirs the softened metal from the two separate pieces, mixing them together under extreme pressure. This action is a type of localized forging. It forces the molecules of the two pieces to intermingle and bond on a microstructural level. 4. Consolidation & Recrystallization 🛡️ As the tool passes, the stirred, forged material behind it immediately begins to cool and solidify. Because it was joined under immense pressure, it recrystallizes into a single, uniform piece of metal with a very fine-grained internal structure. #fsw #liquidcooling #machine #cnc #thermalmanagement
