Plasma cutting. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops ...
Basic mechanism. This is a basic explanation of how a pinch works. (1) Pinches apply a high voltage and current across a tube. This tube is filled with a gas, typically a fusion fuel such as deuterium. If the product of the voltage & the charge is higher than the ionization energy of the gas the gas ionizes. (2) Current jumps across this gap.
A computer numerical control (CNC) router is a computer-controlled cutting machine which typically mounts a hand-held router as a spindle which is used for cutting various materials, such as wood, composites, metals, plastics, glass, and foams. CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle ...
Uses. cutting, heavy demolition. A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, which serve as fuel; these are sometimes mixed with aluminum rods to ...
Metalworking is the process of shaping and reshaping metals in order to create useful objects, parts, assemblies, and large scale structures. As a term, it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges, down to precise engine parts and delicate ...
LOS ANGELES — The VA must build more than 2,500 units of housing for homeless veterans on its sprawling campus in west Los Angeles, a federal judge ruled Friday.. U.S. District Judge David O ...
Compact toroid. Compact toroids are a class of toroidal plasma [1] configurations that are self-stable, and whose configuration does not require magnet coils running through the center of the toroid. They are studied primarily in the field of fusion energy, where the lack of complex magnets and a simple geometry may allow the construction of ...
Dena Smagala’s New York City firefighter husband, Stanley Smagala Jr., died as a first responder to the World Trade Center during 9/11 — and for nearly two decades, she was convinced she'd ...
