How Does Electric Current Generate an Arc in Welding?

Electric current generates an arc in welding by providing a path for the flow of electricity between the welding electrode and the workpiece. The main components involved in this process are the welding machine, the electrode, and the workpiece.

First, the welding machine produces an electric current. This current travels through the electrode as it contacts the workpiece. When the electrode touches the workpiece, a small spark occurs, which creates a localized heat.

Next, the heat generated by the initial spark raises the temperature of the electrode and the surface of the workpiece. This heat is substantial enough to ionize the air gap between the electrode and the workpiece. Ionization creates a conductive plasma channel, which allows the electric current to flow continuously.

Then, the arc establishes as the electric current continues to flow through this ionized air gap. The arc generates extremely high temperatures, which melt the electrode and the base metal, allowing them to fuse together.

Finally, the combination of heat and molten metal forms a strong weld joint. This process relies on controlling factors like current intensity and electrode type to achieve the desired welding results.

In summary, electric current generates an arc in welding by creating a flow of electricity that ionizes air, forming a stable plasma channel. The arc produces the heat needed to melt metal and join materials together.
