What is a Weld Puddle in Welding?

A weld puddle is a molten pool of metal that forms when two pieces of metal are joined together through welding. The size and shape of the weld puddle depend on a number of factors, including:

the type of welding process being used,
the angle at which the weld is being made,
the amount of heat being applied,
and the speed at which the weld is being made.

One of the most important things to remember when welding is to keep the weld puddle small. A large weld puddle can lead to a number of problems, including:

poor weld quality,
excessive heat build-up,
and metal slag inclusion.

What is Puddle arc welding?

Puddle arc welding (PAW) is a type of welding in which the weld puddle is kept under control by using an electrode that is constantly dipped into the puddle. This helps to keep the size and shape of the puddle consistent, which leads to better weld quality.

Stick welding puddle

Stick welding, also known as shielded metal arc welding (SMAW), is a type of welding in which the weld puddle is kept under control by using a stick electrode that is dipped into the puddle.
