Metallintyössä

Metallintyössä refers to metalworking in Finnish. It encompasses a broad range of processes and techniques used to shape and form metal into useful products. These processes can be categorized into several main types, including forming, cutting, joining, and finishing.

Forming processes involve changing the shape of metal without removing material, such as forging, rolling, extrusion, and drawing. Forging heats metal and shapes it with compressive forces, while rolling passes metal through rollers to reduce its thickness or create a specific profile. Extrusion pushes metal through a die to create long shapes, and drawing pulls metal through a die to reduce its diameter and increase its length.

Cutting processes remove unwanted material from a metal workpiece. This can be done mechanically, using saws, drills, or milling machines, or thermally, with methods like oxy-fuel cutting, plasma cutting, and laser cutting. Machining is a common term that encompasses many of these cutting and shaping techniques.

Joining processes are used to connect two or more pieces of metal. Welding is a prevalent method, using heat to melt and fuse metals together, often with the addition of a filler material. Brazing and soldering are similar but use a filler metal with a lower melting point that joins the base metals without melting them. Mechanical fasteners like bolts and rivets also serve to join metal components.

Finishing processes are applied to improve the surface appearance, durability, or functionality of metal parts. This can include grinding, polishing, painting, plating, and anodizing. Each of these stages contributes to the final product's quality and suitability for its intended application. Metallintyössä is fundamental to numerous industries, including automotive, aerospace, construction, and manufacturing.
