One of the significant causes of undercuts in welding is a high voltage current when welding is done by a high current supply or with a continuous long welding electrode.

The groove forms at the welding site, which cause undermines the welding strength.

Moreover, these grooves are also forms at the bottom line of the welding site.


Undercut in welding also affects excellent welder. No one is safe from these defects. The only way to save from undercuts is to reduce the electric current supply. Vey first, workers have the experience to do welding in proper terms. If a welder uses too long a welding electrode, then he also experiences undercut. To prevent these issues, follow the above guideline.


The primary defect of welding is undercutting that eats the base metal due to the high current supply. People in the welding profession must know about; what is undercut in welding? This article acknowledged about undercut in welding and brief the reader about the single-step solution. Also, learn more about what is TIG welding and other details about welding.
