Description and Applications
E320-16 coated electrodes are used for welding Carpenter 20 or 20 Cb-3 stainless steel. Often referred to as 320Cb-16 or 20 Cb-3*, this electrode produces weld deposits that resist chemical corrosion from sulfuric acid, phosphoric acid and their salts. E320-16 is used to weld both castings and wrought alloys of similar analysis without having to do post-weld heat treatment. The Columbium (Cb) content of this electrode gives 320-16 weld deposits excellent resistance to intergranular corrosion.

Procedure
Clean the work area. Preheating is not required. Use DC+ (reverse polarity), however, an AC machine with a minimum open circuit voltage of 70 volts can be used. The welding current should be kept to a minimum and the welding speed at a maximum to avoid overheating and distortion. The arc length should be kept as short as
possible without touching the flux-coating of the electrode to the molten weld pool. The electrode should be tilted 15° in the direction of travel. Stringer beads should be used in the flat, horizontal, & overhead positions.

Vertical welding should be done using the weaving technique but not exceeding 2-3 times the diameter of the electrode. Be sure to remove all slag before making additional passes. On the final pass, allow the part to cool before removing the slag cover.
