Which is better MIG or self shielded flux cored arc welding?
It is accepted that self shielded Flux Cored Arc Welding (FCAW) is less prone to the loss of shielding atmosphere while providing the continuous electrode advantage as Mig does. However breathing FCAW fumes is more dangerous to the welder's health. And of course slag has to be removed between passes and at the end of the process.See all results for this questionWhat kind of current is used in arc welding?Both the direct current (D.C) and alternating current (A.C) may be used for arc welding, but the direct current is preferred for most purposes. When the work is connected to the positive terminal of the D.C welding machine and the negative terminal to an electrode holder, the welding set up is said to have straight polarity.See all results for this questionWhat kind of arc welding is used for sound castings?Gas tungsten arc welding (GTAW) with high frequency stabilized Alternating Current is normally used to repair sound castings. Inclusions should be prevented by taking care to avoid touching the surface with the pure tungsten electrode. Argon with or without helium can be used as a shield. Helium helps generating a hotter arc if necessary.See all results for this question
