Explanation:

1. SMAW is a well - known welding process, and its full form is Shielded Metal Arc Welding.
2. TIG (Tungsten Inert Gas) welding is a different welding process from SMAW. Stick welding, arc welding (in the context of SMAW which is an arc - based process), and manual metal arc welding (another name for SMAW) are related to SMAW.
3. The coating on the electrode in SMAW shields the weld from the atmosphere. The core wire provides electrical conductivity and acts as filler material (to some extent, but the main filler is from the electrode melting). The appearance enhancement is not the primary purpose of the coating.
4. Drive rolls are typically used in wire - feeding welding processes like MIG (Metal Inert Gas) welding. A welding machine, welding helmet, and electrode holder are components of SMAW.

Answer:

1. a) Shielded Metal Arc Welding
2. c) TIG welding
3. c) It shields the weld from the atmosphere
4. d) Drive rolls
