The primary purpose of flux is "to clean". It mixes with the elements in the molten puddle and removes impurities. As it cools it floats to the surface and creates the slag which prevents Oxygen from attacking the Iron.
For steel, flux core or hard wire with Argon/CO2 is used with the GMAW process.
In Submerged Arc Welding (SAW), granular flux can be reused. This type of flux is typically collected after the welding process, cleaned of impurities, and then reintroduced for subsequent welds. The ability to recycle granular flux helps reduce costs and minimize waste, while still providing the necessary shielding and alloying properties during welding. However, the reuse of flux should be monitored to ensure its performance is not compromised.

Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
Resistance welding plants are used in fence manufacturing.
For steel, flux core or hard wire with Argon/CO2 is used with the GMAW process.
Emery cloth and non acid type flux
The gas acts as the flux would, in shielding the molten steel from the oxygen in the air.
No, the main limitation of flux-cored arc welding is not restricted to ferrous metals. While it is commonly used for welding ferrous metals, it can also be used for welding some non-ferrous metals with the correct types of flux-cored wire. The main limitations typically involve issues like weld quality, porosity, and slag removal.
Flux is any material used to aid in the purification of smelted metals and cleaning or joining of metal in welding. it is a Metallurgy term.
The flux used for hammer welding damascus steel is typically a borax-based flux. Borax helps to prevent oxidation and facilitate the welding process by cleaning the metal surfaces and promoting a strong bond between the layers of steel. It is applied to the steel before heating and hammering to create a solid weld.
Welder slag is a byproduct resulting from the welding process, often forming a layer on top of the welded joint. It consists of the residue from the flux used in the welding rod or wire, which helps protect the weld pool from impurities and contaminants while it cools. Slag is typically removed after welding to inspect the quality of the weld and ensure proper fusion.
What type of welding can we use LPG ?
The arc welding process that deposits a layer of granular flux over the weld area is known as Submerged Arc Welding (SAW). In this method, the welding arc is submerged under a thick layer of granular flux, which protects the weld pool from atmospheric contamination and helps to stabilize the arc. The flux also contributes to the formation of a slag layer that can improve the quality of the weld. This process is commonly used for welding thick materials and in industrial applications due to its efficiency and effectiveness.
A welding chipping hammer is a hand held tool, like yourself. It is used for removing slag after the SMAW or flux core process.
Yes .... but most welds will not be as good as those using flux. SMAW with bare electrodes produces poor results. GTAW and GMAW are done without flux when an inert gas is used to protect the puddle. Some Oxy-fuel welding can be done with out it. In most applications flux is used not only to protect the molten puddle but also add ingredients to the weld.
