Bohler EASN 2 Si-IG for GTAW Bohler FOX EAS 2Si for SMAW
For GTAW Process use ER90-B9 and for the SMAW Process use E 9018-B9, or E 9015-B9
Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.
In European Shipbuilding Industries used SMAW,GTAW,GMAW,SAW,FCAW(MAG). In INDIAN Shipbuilding Industries used, LBW,EBW,EGW,ESW,FCAW,SAW.
smaw welding is sheilded metal arc welding
There is two technique of arc initiation, first TAPPING Technique and second SCRATCH Technique. TAPING Technique is generally use in GTAW and SCRATCH Technique is used for SMAW process.
GAS TUNGSTEN ARC WELDING
The minimum thickness for SMAW welding is about 18 ga. with a steady hand.
The tip of the tungsten electrode has to be hot in GTAW because you are trying to weld two pieces of metal together, and that takes a lot of heat.
Advantage of smaw :*equipment is relatively inexpensive Equipment is portable because the welding machine can be powered with gasoline or diesel powered w/ engines.
