What is the difference between slag and flux?
Hint: Flux is a substance which we add to molten metal to bond with impurities that can be removed afterwards, slag is a waste material which is removed. Fluxes are used during refining of metals and slag is impure residue.
What is flux and slag with example?
Flux is a substance added to molten metals to bond with impurities that can be readily removed while slag is the waste material which is removed. Example: CaO is a impurity, to remove it SeO2 (sand) is used as flux to produce CaSiO3 as slag.
What effect does slag have on a vertical weld?
Type of flux coating For vertical welding, the slag must be more fluid to flow out to the weld pool surface but have a higher surface tension to provide support to the weldpool and be fast freezing.
What is the purpose of slag?
While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.
What is flux and slag?
1)Flux is the material or substance thats is added to molten metals to bond with impurities that can be readily removed whereas slag is the waste material which is removed. Fluxes are used during the refining of metals.
What are the two types of flux?
The so called water soluble fluxes are divided into two categories, organic and inorganic based on composition. Organic fluxes are more active than RA rosin, and inorganic are the most active of all.
What is slag example?
Slag is waste matter separated from metal during smelting. An example of slag is the iron and silica that is removed during copper and lead smelting. An example of to slag is for the heat of copper smelting to remove the iron and silica from the copper.
What is flux in welding?
Weld flux is a chemical purifying agent, flowing agent or cleaning agent. It is commonly used in metal joining and metallurgy. The primary purpose of weld flux is to prevent oxidation of the base and filler materials during the welding process.
What is slag welding?
The American Welding Society (AWS) defines slag as “a nonmetallic byproduct of the mutualdissolution of flux with nonmetallic impurities in welding and brazing processes.” In short, it is the hardened layer left on the top of weld made during flux-cored welding (FCAW).
What is called slag?
Slag is the silicon dioxide and metal oxide mixture left over as a by-product of extracting metal from its ore during the smelting process. Slag consists of the undesired impurities in the metal ore extracted during the smelting process.
What is flux with example?
Flux is a chemical purifying agent, flowing agent or cleaning agent. Most commonly, it is used in metal joining and metallurgy. Some examples of flux include: Ammonium chloride. Zinc chloride.
What exactly is flux?
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field . Flux is depicted as “lines” in a plane that contains or intersects electric charge poles or magnetic poles.
What is the difference between flux and slag?
(1)difference between flux and slag. Flux is the substance added to to molten metals to bond with impurities that can be readily removed. Slag is the waste material which is removed. In metallurgy, substance used to remove or prevent the formation of undesirable oxide and other substances during welding.Jul 11, 2015
What is the meaning of slag when welding?
Slag is the coating left on the weld by the flux. The flux serves a couple of purposes. First some of it burns off into a gas that shields the weld puddle from the atmosphere. Second it helps the weld metal coalesce (mix) with the base metals while pulling impurities out of the weld.
When does flux convert to slag in SMAW welding?
In SMAW welding, the coating in the electrode is known as flux. When the electrode is struck and starts melting, the flux melts and an insulating blanket is formed over the weld metal. That insulating blanket is called slag. In other words, flux converts to slag when the welding progresses.
What is the meaning of flux in metallurgy?
Flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores.
