IN SAW WHY SLAG OCCURS?
Flux core arc welding
In European Shipbuilding Industries used SMAW,GTAW,GMAW,SAW,FCAW(MAG). In INDIAN Shipbuilding Industries used, LBW,EBW,EGW,ESW,FCAW,SAW.
The main difference between Flux-Cored Arc Welding (FCAW) and Gas Metal Arc Welding (GMAW) is the type of consumable electrode used. FCAW uses a tubular electrode filled with flux to protect the weld pool, while GMAW uses a solid wire electrode with an external shielding gas. FCAW is often preferred for outdoor welding due to its self-shielding capabilities, while GMAW generally produces cleaner welds.

FCAW (Flux-Cored Arc Welding) wire contains a flux that generates shielding gas and slag during the welding process, which can be used in both indoor and outdoor environments. In contrast, GMAW (Gas Metal Arc Welding) wire is solid and relies on an external shielding gas to protect the weld from contamination, making it best suited for clean environments. Additionally, FCAW can be used on thicker materials and is often preferred for heavy-duty applications, while GMAW provides a cleaner weld and is typically used for thinner materials.
There are, yes, and tubular electrodes are very common (Flux-Cored Arc Welding (FCAW)). The electrode in this process is a tubular wire which is filled with fluxing and alloying element. Such electrodes have increased penetration depth, deposition, and quality enhancement of the weld and robustness over solid wires. Tubular electrodes are particularly prone to heavy fabrication, structural welding tasks and also effective in outdoor set ups where lack of shielding gas may occur.

At steel structures on-site of a building, the most common type of welding used is Shielded Metal Arc Welding (SMAW), also known as stick welding. This method is favored for its versatility and effectiveness in outdoor conditions, where wind and other environmental factors may affect other welding processes. Additionally, Flux-Cored Arc Welding (FCAW) is also utilized for its high deposition rates and ability to weld thicker materials. Both techniques are suitable for structural applications and provide strong, durable joints essential for building integrity.
The American Welding Society abbreviations for the arc welding processes that melt a tubular electrode with alloys deoxidizers and slag formers in their cores are FCAW (Flux-Cored Arc Welding) and metal-cored arc welding (MC).
The amount of weldable meters from a 15kg spool of FCAW 71T wire depends on several factors, including the wire diameter and the type of joint being welded. Generally, a rough estimate is that 1 kg of wire can weld approximately 1 to 1.5 meters, depending on the application. Therefore, a 15kg spool could yield around 15 to 22.5 meters of weld. For precise calculations, it's best to refer to specific welding parameters and joint designs.
MIG stands for metal inert gas. It is a non-standard term for gas metal arc welding (GMAW) and flux cored arc welding (FCAW) according to the American Welding Society (AWS). It is simply Metal Inert Gas.
FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage. An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon. The process is widely used in construction because of its high welding speed and portability. Cored electrodes produce a more stable arc, improve weld contour, and improve mechanical properties of the weld metal. Porosity and costly filler material as compared to GMAW.
A certified welder is one who has successfully passed the requirements of an industry specification for welding in a particular process (SMAW, GMAW, FCAW, GTAW), and in a specific position (1G, 2G, 3F, 6G, etc.), with a specific material (mild steel, aluminum, stainless, etc.) The certification relates only to the specification that was qualified to, in the position qualified, on the material qualified, and only with the process used. A master welder is one who can, or has, passed the most restrictive position (Usually 6G), in all processes, and in many different material groups. There is no mention of "master welder" in welding specifications, it is usually an internal company designation. It is expected that a Master Welder can weld any material, in any position, with any process.
