Electric arcs are created when electricity jumps between two electrodes, forming a bridge of electrons visible to the eye. The temperature and brightness of the arc depend on gas type and pressure. Electric arcs are used for welding, lighting, and melting metals. They can also be used for plasma speakers. Nikola Tesla’s Tesla coil and […]
Gas tungsten arc welding uses a tungsten electrode to create a clean weld with less contamination. It is used on thin and non-ferrous metals, requires a shielding gas and filler rod, and produces no smoke. Protective gear is necessary due to the high heat and UV rays. Gas tungsten arc welding is a type of […]
Stick welding uses a two-piece electrode with a metal alloy core and silicon-based flux to create strong welds. Moisture and incorrect heat settings cause porosity, while spatter indicates excessive heat. Proper handling and direction of the electrode ensure a structurally sound weld. Shielded metal arc welding, also known as stick welding, uses a two-piece electrode […]
Plasma arc welding is a more focused and automated process than gas tungsten arc welding, using a narrow copper orifice to create a plasma arc that can reach high temperatures and speeds. It requires at least two types of gas and can be varied based on key components. However, it is more expensive and complex, […]
Flux Core Arc Welding (FCAW) is a welding process that uses a flux-filled consumable hollow electrode. It can use external shielding gas or rely on the flux content of the electrode. FCAW has advantages over shielded metal arc welding, including high welding speeds and less pre-cleaning. FCAW machines work with constant voltage or current power […]
An arc welder uses electric current to melt steel and join pieces together with a welding rod. The rod is covered in flux to protect the weld from contaminants. The traditional arc welder is being replaced by the MIG welder, which uses a coil of wire and a shielding gas. The TIG welder uses a […]
Welding is the process of bonding materials by melting metal or thermoplastic surfaces. Arc welding is a common metal welding process that uses a high energy power supply to create an electric arc between the welding tool and the material being welded. Gas metal arc welding (GMAW) and flux core arc welding (FCAW) are two […]
Submerged arc welding uses a flux layer to cover the area being welded, providing benefits such as reduced UV radiation and a higher quality weld. It can be done indoors or outdoors and is excellent for joining thin sheet metal quickly. However, it has limitations in the materials it can be used on and concerns […]
An arc converter generates audible or radio frequency energy using an electric arc between two conductors. It requires high initial voltage and constant current to sustain the arc. The arc generated contains a broad spectrum of frequencies and can be tuned to a specific frequency using a tuned electrical circuit. The resonant or tuned circuit […]
An electric arc furnace uses an electric arc to melt materials, typically metals. It has a shell with a domed bowl, electrodes, and a refractory hearth. AC or DC power sources can be used, and additives are often used to promote chemical balance. Arc furnaces offer flexibility, quick shutdown and restart, and are cheaper to […]
Learning arc welding requires practice, persistence, and attention to detail. One can learn through self-practice, apprenticeships, technical colleges, or by seeking help from friends and family. Safety equipment is crucial, and willingness to practice is key to becoming a skilled welder. Arc welding is a skilled and often complex task, requiring attention to detail and […]
“Story arc” is a literary term for a narrative plot or subplot that includes a setup, escalating conflict, and resolution. It is used in TV series, soap operas, and comic books. “Character arc” describes the change and growth of a character. Multiple story arcs can occur at the same time, and they are labeled as […]
Arc eye is a painful condition caused by UV radiation, often from welding. Symptoms include blurred vision and eye pain. Mild cases can be treated with eye drops and ointment, but serious injuries require emergency care. Prevention includes wearing eye protection and avoiding UV exposure. Arc eye is a condition in which the outer layer […]
“Shot across the bow” is a nautical term originating from the 18th century, used to identify a ship’s country. It has a literal and figurative meaning, and is now used as a warning shot in modern times. Expressions in the English language come from various sources, such as foreign languages. Another popular source of colorful […]
