Welding - Answer-the joining of metals at their molecular level; manipulating heat Pulse welding - Answer-by forming one droplet of molten metal at the end of the electrode Then, just the right amount of current is added to push that one droplet across the arc and into the puddle. The transfer of these droplets occurs through the arc, one droplet at a time 4 Components of a Weld - Answer-Metal, Heat Source, Filler Metal, Shield from Air 4 ARC Welding Processes - Answer-stick, mig, tig, plas...
