Puddle In Welding Link

In manual welding (SMAW, GMAW, FCAW, GTAW), the (or molten pool) is the small, liquid volume of metal directly beneath the arc. Controlling this puddle is the single most important skill a welder can develop.

The welding puddle (or weld pool) is the small volume of molten metal created at the point where the heat source (arc, flame, or laser) meets the base metal. It is the "mixing bowl" where the filler metal and the base metal combine to create a permanent bond. puddle in welding

Once the heat source moves away, this molten pool cools and solidifies to form the final weld bead. In manual welding (SMAW, GMAW, FCAW, GTAW), the
