What is a Clear Puddle in Welding?

In welding, a clear puddle is defined as a pool of molten metal that is free from impurities or contaminants. This type of puddle is necessary in order to create a high-quality weld joint.

In order to achieve a clear puddle, the welder must use a clean electrode and must clean the area around the weld joint before beginning the welding process. If there are any impurities present in the puddle, they can cause the weld joint to be weak or to fail entirely. Therefore, it is crucial that the welder takes the time to create a clear puddle in order to produce a strong, high-quality weld.

How do you read a welding puddle?

In order to read a welding puddle, the welder must be able to understand the different colors that the puddle can take on.

The color of the puddle can indicate the temperature of the metal and can also tell the welder whether or not the weld is being performed correctly.
For example, a blue puddle indicates that the metal is too cold and needs to be heated up before welding can continue.
On the other hand, a yellow puddle means that the metal is too hot and needs to be cooled down before continuing.

How do you control weld puddles?

In order to control weld puddles, the welder must have a good understanding of how the welding process works.

What is debris from welding called?

Debris from welding is typically called slag. Slag is a type of impurity that can be found in the welding puddle. Slag is typically made up of oxides and other contaminants that are present in the metal being welded. When slag is present in the puddle, it can cause the weld joint to be weak or to fail entirely. Therefore, it is important for the welder to remove all slag from the puddle before continuing with the welding process.

What is a pinhole in welding?

A pinhole is a small hole that is present in the weld joint. Pinholes are typically caused by impurities in the welding puddle. When impurities are present in the puddle, they can cause the weld joint to be weak or to fail entirely. Therefore, it is important for the welder to remove all impurities from the puddle before continuing with the welding process.

Difference between pinhole and porosity in welding

Porosity is a type of impurity that is present in the welding puddle. Porosity is typically caused by gas bubbles that are present in the metal being welded. A pinhole is a small hole that is present in the weld joint. Pinholes are typically caused by impurities in the welding puddle.
