This is used differently in different countries. But generally, if a welder is contracted to do say 100 weld joints, of a 1" pipe, then the total work involved is 100" dia welding work. If 100 weld joints of a 2" pipe is 200 weld work and so on.
the basic principle of welding is 1. first we have some broken material 2. a welder 3. welder should know how to weld

A spot welder uses 2 electrodes positioned opposite each other. 2 pieces of metal (usually thin) are placed like a sandwich between the electrodes which come together with force and an electrical current is passed thru them which actually melts the pieces where they touch each other. This produces a small weld "spot" . This spot is about the same size as the tips of the electrodes.
