What is a Conductor in Welding?

A conductor is a material that has a relatively large number of loosely bonded electrons that may move freely when voltage (electrical pressure) is applied. Metals are good conductors.

In welding, the conductor is used to carry the current from the power source to the electrode. The size and type of conductor used to depend on the amperage and voltage of the power source, as well as the type of electrode being used.

2 types of welding conductors

There are two types of welding conductors:

Solid conductors are made of a single piece of metal,
while stranded conductors are made of multiple smaller pieces of metal (strands) twisted together.

Which type of conductor is best for welding?

It depends on the application. Stranded conductors are more flexible than solid conductors, so they are better suited for applications where the conductor will need to be bent or moved around. Solid conductors are more durable than stranded conductors and can carry more current, so they are better suited for high-amperage applications.

What is electricity in welding?

Electricity is the flow of electrons through a material. In welding, the electrode and the workpiece are conductors. The power source provides the voltage (electrical pressure) that causes the electrons to flow.

What is work lead in welding?

A work lead is a conductor that carries the current from the power source to the workpiece. The size and type of conductor used to depend on the amperage and voltage of the power source, as well as the type of electrode being used.

Crater definition welding

A crater is a depression that forms at the end of a welding arc. Craters are caused by the sudden cooling of the molten metal as it comes into contact with the air. Craters can be prevented by using proper welding techniques, such as maintaining a short arc length and keeping the electrode tip clean.
