Using basic-type flux cored wires significantly improve the toughness of weld joints, but the addition of fluoride decreases the weld-ability of the metal.In this paper, the flux cored tungsten inert gas (FCTIG) process was used to weld DH36 steel with a basic-type flux cored wire and a rutile-type flux cored wire. The microstructure and …

Shielded metal arc welding process can work on both AC and DC. The constant current DC power source is invariably used with all types of electrodes (basic, rutile and cellulosic) irrespective of base metal (ferrous and non-ferrous). However, AC can be unsuitable for certain types of electrodes and base metals.

The slag is usually self-removable with rutile coating rods. The weld metal hydrogen level is high for rutile covering rods and hence they are not suitable for welding high-strength & thick materials. Examples of rutile coating rods are: E6013 (E 38 0 RC 11), E7024 (38 0 RR 54), and E71T-1 flux cored wire. Type RB (rutile basic)
