Braze welding is the use of a bronze or brass filler rod coated with flux to join steel workpieces. The equipment needed for braze welding is basically identical to the equipment used in brazing. Since braze welding usually requires more heat than brazing, acetylene or methylacetylene-propadiene gas fuel is commonly used. The name comes from ...
Ador Welding Limited (formerly known as Advani–Oerlikon Limited) is an industrial manufacturing company headquartered in Mumbai, India.The flagship company of the Ador Group, Ador Welding produces a variety of welding products, industry applications, and technology services, including welding consumables (electrodes, wires, and fluxes) as well as welding and cutting equipment.
Hot gas welding, also known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic. (Welding PVC to acrylic is an exception to ...
Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound.
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1]
Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
Comair Limited was a public company listed on the Johannesburg Stock Exchange (JSE: COM), [14] but after going into business rescue on 5 May 2020, the company was delisted from the Johannesburg Stock Exchange on 7 April 2021; this gave it access to ZAR100 million rand (USD6.8 million) under the COVID-19 Loan Guarantee Scheme put in place between the South African Reserve Bank and large ...
