A weld symbol is the shape drawn on a Print to tell the welder: how to prepare a welding joint, what process can be used to weld (mig, tig, arc, etc) what filler rod to use, how wide and long the weld should be, how to deal with the weld after your done (grind flush, brush clean, or nothing) and a million other things....

Its a tool that design engineers use to communicate what the weld needs to be to meet their design specifications.

What is meant by the term welding and draw various welding symbols?

Welding is the process of joining two metals, usually involving a heat source. Welding symbols are the symbols used on part prints or assembly drawings to show size and type of weld, the specific welding process, and many other variables pertaining to that particular weld. A welding symbol looks like an arrow pointing to the location of the weld, with a horizontal line 'carrying' other symbols and numbers that describe how to make that weld. A picture of a welding symbol can be found when an image search is done.
