Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding using chemicals to melt materials being bonded without heat, and solid-state welding processes which bond without melting, such as pressure, cold welding, and diffusion bonding.
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 jewelry.
Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC are used to direct the laser beam to the material. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.
A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, as opposed to drawing dies and casting dies which are not. Like molds, dies are generally customized to the item they are used to create.
Industrial processes are procedures involving chemical, physical, electrical, or mechanical steps to aid in the manufacturing of an item or items, usually carried out on a very large scale. Industrial processes are the key components of heavy industry.
Laser engraving is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which in some cases, also includes color change due to chemical/molecular alteration, charring, foaming, melting, ablation, and more. The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out, giving it an advantage over alternative engraving or marking technologies where inks or bit heads have to be replaced regularly.
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added process involving the creation of machines, parts, and structures from various raw materials.
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process.
Republic Steel is an American steel manufacturer that was once the country's third largest steel producer. It was founded as the Republic Iron and Steel Company in Youngstown, Ohio in 1899. After rising to prominence during the early 20th Century, Republic suffered heavy economic losses and was eventually bought out before re-emerging in the early 2000s as a subsidiary. The company currently manufactures Special Bar Quality (SBQ) steel bars and employs around 2,000 people. It is currently owned by Grupo Simec, based in Guadalajara, Mexico.
The Birmingham District is a geological area in the vicinity of Birmingham, Alabama, where the raw materials for making steel - limestone, iron ore, and coal - are found together in abundance. The district includes Red Mountain, Jones Valley, and the Warrior and Cahaba coal fields in Central Alabama.
Electron-beam additive manufacturing, or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts. The raw material is placed under a vacuum and fused together from heating by an electron beam. This technique is distinct from selective laser sintering as the raw material fuses have completely melted. Selective Electron Beam Melting (SEBM) emerged as a powder bed-based additive manufacturing (AM) technology and was brought to market in 1997 by Arcam AB Corporation headquartered in Sweden.
Sumitomo Electric Industries, Ltd. is a manufacturer of electric wire and optical fiber cables. Its headquarters are in Chūō-ku, Osaka, Japan. The company's shares are listed in the first section of the Tokyo, Nagoya Stock Exchanges, and the Fukuoka Stock Exchange. In the period ending March 2021, the company reported consolidated sales of US$26,5 billion.
Carpenter Technology Corporation develops, manufactures, and distributes stainless steels and corrosion-resistant alloys. In fiscal year 2018, the company's revenues were derived from the aerospace and defense industry (55%), the industrial and consumer industry (17%), the medical industry (8%), the transportation industry (7%), the energy industry (7%), and the distribution industry (6%). The company's products are used in landing gear, shaft collars, safety wires, electricity generation products, intervertebral disc arthroplasty, and engine valves and weldings.
The Tennessee Coal, Iron and Railroad Company (1852–1952), also known as TCI and the Tennessee Company, was a major American steel manufacturer with interests in coal and iron ore mining and railroad operations. Originally based entirely within Tennessee, it relocated most of its business to Alabama in the late nineteenth century, following protests over its use of free convict labor. With a sizable real estate portfolio, the company owned several Birmingham satellite towns, including Ensley, Fairfield, Docena, Edgewater and Bayview. It also established a coal mining camp it sold to U.S. Steel which developed it into the Westfield, Alabama planned community.
Photochemical machining (PCM), also known as photochemical milling or photo etching, is a chemical milling process used to fabricate sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960s as an offshoot of the printed circuit board industry. Photo etching can produce highly complex parts with very fine detail accurately and economically.
Olympic Steel, Inc. is a metals service center based in Cleveland, Ohio. The company processes and distributes carbon, coated and stainless flat-rolled sheet, coil and plate steel, aluminium alloy, tin plate, and metal-intensive branded products primarily in the United States. Metals processing and value added services include tempering, stretch leveling, cutting-to-length, slitting, edging, shearing, blanking, burning, forming, shot blasting, laser punching, plate rolling, fabricating, machining, and welding. Its Chicago Tube & Iron subsidiary is a distributor of steel tubing, pipe, bar, valves & fittings, and fabricates pressure parts.

In 1887, Richard Knight LeBlond founded the R. K. LeBlond Machine Tool Company in Cincinnati, Ohio to manufacture metal cutting lathes. The LeBlond Aircraft Engine Corporation was formed as a subsidiary in 1928. As a result of a joint venture with Makino Milling Machine, LeBlond Makino Machine Tool Company was formed in 1981. In 1996, LeBlond Makino Machine Tool Company changed its name to Makino. Then in 1997, LeBlond Lathe Parts was founded to focus on the service and support of all LeBlond lathe equipment manufactured since 1887. In 1998, after acquiring the W. F. & John Barnes Company, the company's name was changed to LeBlond Ltd to reflect a broader business purpose. LeBlond continued its acquisition strategy by acquiring the Standard Modern lathe service parts business in 1999. The Johnson Press and Deka Drill service parts businesses were acquired from South Bend Lathe in 2001 and the South Bend Lathe and Dynablast parts businesses in March, 2002. LeBlond's product support team had collectively 160 years of service with LeBlond Machine Tool Company, LeBlond Makino and Makino.
Selective laser melting (SLM) is one of many proprietary names for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering (DMLS), the ASTM standard term is powder bed fusion (PBF). PBF is a rapid prototyping, 3D printing, or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together.
