steelcutting

Steelcutting refers to the process of dividing steel into smaller, usable pieces. This is a fundamental step in metal fabrication and construction, preparing raw steel or semi-finished products for further processing or assembly. Various methods are employed depending on the thickness of the steel, the desired precision, and the available equipment.

Common steelcutting techniques include sawing, shearing, plasma cutting, and oxy-fuel cutting. Sawing utilizes mechanical blades to cut through the metal, suitable for a wide range of thicknesses and offering a clean edge. Shearing is a rapid method that uses opposing blades to slice through thinner steel sheets, often employed for bulk cutting. Plasma cutting employs a high-temperature plasma torch to melt and blow away the steel, allowing for intricate shapes and faster cutting of medium thicknesses. Oxy-fuel cutting, also known as gas cutting, uses a flame to preheat the steel and then a jet of pure oxygen to oxidize and blow away the molten metal, typically used for thicker steel sections.

The choice of steelcutting method impacts the quality of the cut, including edge perpendicularity, surface finish, and the presence of heat-affected zones. Proper selection ensures efficiency, material integrity, and cost-effectiveness in various industrial applications, from shipbuilding and bridge construction to the manufacturing of machinery and consumer goods.
