  • Welding — is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle ) that cools to… …   Wikipedia

  • Continuous cooling transformation — diagram of EN S355 (ASTM A 572 Grade 50, warranted yield stress 355 MPa) for welding (fast cooling, linear scale). A continuous cooling transformation (CCT) phase diagram is often used when heat treating steel.[1] These diagrams are used to… …   Wikipedia

  • welding — Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved …   Universalium

  • Continuous casting — The macrostructure of continuously cast copper (99.95% pure), etched, ∅ ≈ 83 mm. Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a semifinished billet, bloom, or slab for subsequent rolling… …   Wikipedia
