![]() Key Variables Of Flux Cored Arc Weldingįlux Cored Arc Welding is characterized by the following features: There is a reason behind it, and we will discuss it separately in another article. However, flux cored welding aluminum is not possible. Among them, flux cored welding stainless steel is commonly used. Which Metals Can Flux Cored Arc Welding Be Applied?įlux Cored Arc Welding can be performed on most mild steels, stainless steels, cast iron and other surfacing alloys. Picture 04 – Overview on Gas-shielded Flux Cored Arc Welding (FCAW-G). Out-of-position welding, such as vertical up or overhead, becomes easier with FCAW-G. ![]() The most commonly shielding gas applied for FCAW-G is either Pure CO2 or the C25 (75% Argon and 25% CO2).įCAW-G is commonly found in maintenance and shipbuilding projects. It is sometimes referred to as the combination of MIG welding and Flux Cored Arc Welding. Gas-shielded Flux Cored Arc Welding (FCAW-G)įCAW-G was created mainly to weld structural steels. Picture 03 – Overview on Self-shielded Flux Cored Arc Welding (FCAW-S). You will find FCAW-S in many outdoor constructions where the bulky cylinder of shielding gas is not readily available. However, you will need external shielding gas for this particular FCAW type.įCAW-S is often applied outdoors or for projects with special requirements (such as welding galvanized steels). Hence, the slag created by this type is easier to remove. The flux composition in gas-shielded FCAW is quite similar to that in self-shielded FCAW, but its degree of protection in the weld pool is weaker. Thus, it does not rely on the external shielding gas and can be performed in outdoor conditions. The fluxing agents in self-shielded FCAW bear two functions: to deoxidize the weld pool and to shield the weld pool and metal droplets from contaminants. Self-shielded Flux Cored Arc Welding (FCAW-S) The difference between the two above process types is the composition of fluxing agents located inside the flux core wires. Picture 02 – Two common processes of Flux Cored Arc Welding. Two Popular Types Of Flux Cored Arc Weldingįlux Cored Arc Welding has two common process types: self-shielded FCAW (or FCAW-S), and gas-shielded FCAW (or FCAW-G). Upon being melted, the flux composition inside the hollowed core of the wires generates shielding gas and later, slag layer, to protect the weld puddle from contaminants. One unique feature of Flux Cored Arc Welding lies in its flux core wires. If I have to point out two special traits of Flux Cored Arc Welding, it would be “high welding speed” and “high portability”. This change helps Flux Cored Arc welding overcome many limits that belong to the SMAW process. It has many superior advantages over its stick welding pal, one of which is the removal of the bulky external shielding gas. General Definition About Flux Cored Arc Weldingįlux Cored Arc Welding, sometimes referred to shortly as FCAW, is a semi-automatic (or automatic) arc welding process that utilizes a continuously-fed consumable tubular electrode ( Flux Core Wire) and a constant-voltage power supply (mainly DCEP settings).īeing considered as the sub-type of MIG welding process, FCAW was firstly invented in the early 1950s as an upgraded version to Stick welding (or Shielded Metal Arc Welding, SMAW). In this first section, we will look over some general definitions and how flux cored arc welding is applied in the real world. No more waiting! Let’s jump right in! Picture 01 – The Basic Tutorial Of Flux Cored Arc Welding (FCAW) For Beginners What Is Flux Cored Arc Welding (FCAW)? Some brief comparisons between Flux Cored Arc Welding and MIG, Stick Welding.The complete process of Flux Cored Arc Welding.Basic equipment of Flux Cored Arc Welding.Benefits and drawbacks of using Flux Cored Arc Welding.What exactly is Flux Cored Arc Welding?.In this article, let’s uncover all the basic information about Flux Cored Arc Welding, from: This process had erased all those hassles and brought superior advantages to the job. If you are so tired of all the hassle of Stick Welding, then you should definitely check out Flux Cored Arc Welding.
