Flux-cored Arc Welding (FCAW) is functionally identical to GMAW/MIG welding, except that the continuously-fed consumable electrode wire delivered through the torch is hollow and filled with a flux. Email Address. As far as expense, flux core wire can be more expensive to run, though the low initial startup cost of welding with a dedicated Flux core machine makes it initially more appealing. This power supply creates an arc between a consumable or non-consumable electrode, passing either AC or DC current to the base material. This fusion welding uses AC or DC power supply as its source of heat. Marty Rice is a welding instructor at a high school career center in Texas. Some of the most common uses for arc welding include steel erection, heavy equipment repair, pipeline welding and many major construction projects. Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. Two of the most common kinds of arc welding used in industrial processes are gas metal arc welding and flux cored arc welding. It is a fusion welding process. In flux cored arc welding, a tubular wire is filled with the flux material. Flux cored welding advantages and disadvantages. by Marty Rice . Advantages. Flux Core Arc Welding (FCAW) Advantages & Disadvantages . Zip Code. It is also known as Manual metal arc welding; stick welding or electric arc welding. The flux is contained directly inside the core of the tubular electrode. Fill out the form to recieve a no obligation info packet. It melts during the welding and is then able to shield the weld from the atmosphere. When using FCAW, a welder does not have to stop and change rods as in SMAW. You are giving your express written consent for Tulsa Welding School to contact you regarding our educational programs and … He is the author of Arc Welding 101, which appears in each issue of Practical Welding Today®, and is an honorary member of the Iron Workers Local 263. When the ark is initiated between the wire electrode and the workpiece, the filler is heated, allowing it to blend with the material to create the weld. Arc welding is a welding process that use an electric arc to create enough heat to melt a metal, it cools and result to bonding of the metals. Full Name. Phone Number. Arc welding can use either direct or alternating currents, and uses consumable or non-consumable electrodes coated in flux. The advantages of flux-cored arc welding include: Have You Considered a Career in Welding or HVAC? Welding is performed with the heat of an electric arc that is maintained between the ends of a coated metal electrode and the work piece. A shielding gas can be used in conjunction with the process, but typically the flux generates the necessary atmospheric protection by producing both gaseous protection and a liquid slag over the weld. The positive aspects of a wire with a cored flux versus solid wire with gas surrounding it appeals to many people especially beginners. The temperatures in arc welding get up as high as 6,500 degrees Fahrenheit.
