11/30/2023 0 Comments Flux core welds![]() Using filler metals with added deoxidizers also helps weld through such contaminants, but these products should never replace proper pre-cleaning. To prevent this problem, remove any rust, grease, paint, coatings, oil, moisture and dirt from the base metal prior to welding. It can appear at any specific point on the weld or along its full length. Porosity results when gas becomes trapped in the weld metal. Porosity and wormtracking are both common weld discontinuities that can weaken the integrity of your welds. The two most prevalent type of wire feeding problems-burnback and birdnesting-tend to extinguish the arc prematurely, which in turn can lead to weld defects. They can cause a considerable amount of downtime. Wire feed stoppages and malfunctions are common problems on many job sites. ![]() Fortunately, with some know-how and a bit of practice, you can prevent some of the common problems associated with the process and gain the weld quality you need. Still, it doesn’t mean that the process is without its challenges. That’s not surprising, as it offers high deposition rates, excellent chemical and mechanical properties, and the weldability required for these jobs. It has been useful for structural steel erection, heavy equipment repair, bridge construction and other similar applications. Self-shielded flux-cored arc welding (FCAW) has been a viable welding process many years. Dura-Flux Self-Shielded Flux-Cored Gun with Replaceable Cable Linerįlux-cored welding offers many advantages when welding on construction applications, including high disposition rates, and good chemical and mechanical properties.Dura-Flux Self-Shielded Flux-Cored Gun with Fixed Cable Liner.Our application experts can also advise you on the mixture and operating mode best suited to your needs, also supporting you with the equipment and gas management services you need. These include improved productivity combined with high quality across a range of plain carbon, alloy, stainless and duplex steels. These mixes have been designed to bring you the full benefits of FCAW welding. We deliver a range of tried-and-tested FCAW welding gases under our CORGON ®, CRONIGON ®, VARIGON ® and FORMIER ® families. Self-shielding operation where gas is produced when fluxing agents decompose within the wire ![]() Gas-shielded operation where a shielding gas is supplied from an external source, such as a gas cylinder It also typically enables higher wire deposition rates and greater arc stability although the process efficiency of MIG is usually superior. It offers more flexibility with alloy compositions than MIG, for instance. It can also be used for surfacing and hardfacing.įCAW is a variant of the MIG/MAG process and while there are many common features between the two processes, there are also several fundamental differences. The entire arc area is covered by a shielding gas, which protects the molten weld pool from the atmosphere.įCAW is a highly productive process for a range of plain carbon, alloy, stainless and duplex steels. The arc is struck between a continuously fed consumable filler wire and the workpiece, melting both the filler wire and the workpiece in the immediate vicinity. ![]() PLASTINUM Dynamic Temperature Control with CO₂įlux-Cored Arc Welding (FCAW) uses the heat generated by a DC electric arc to fuse the metal in the joint area.
