Undercut can occur for several reasons: Excessive heat from high current and voltage settings. If the travel speed is too fast, the electrode moves away from the weld pool prematurely. If edges are not prepared properly dirt or grit on the welding surfaces tends to block heat transfer which can cause undercutting.

What is undercut means in welding?
Supply. Gases. 5 UNDERCUTTING As shown in Figure 10-3, undercutting is a defect that appears as a groove in the parent metal directly along the edges of the weld. It is most common in lap fillet welds, but can also be encountered in fillet and butt joints.

How do welders avoid undercuts?
The root pass is the first weld that is performed on an open joint. Undercutting can often occur at the root pass of a welded point. The way to prevent this from occurring is to not push the electrode in too far when performing the root pass on a pipe.

What is undercut and why does it happen?
An undercut is a surface and subsurface defect resulting from grooves within the parent metal area. Like all other defects, instead of improving the joint strength, it introduces weak points that often propagate structural failure.
What causes undercut when welding?
Undercut can occur for several reasons: Excessive heat from high current and voltage settings. If the travel speed is too fast, the electrode moves away from the weld pool prematurely. If edges are not prepared properly dirt or grit on the welding surfaces tends to block heat transfer which can cause undercutting.
