Common Mistakes to Avoid in Arc Welding
Even experienced welders can face challenges that compromise weld quality. Issues like surface porosity and undercut can weaken joints, leading to structural failures. Understanding these defects is crucial for producing strong, durable welds.
Surface Porosity and Pinhole Defects
Surface porosity occurs when gas bubbles become trapped in the weld, creating tiny holes. These pinhole defects weaken the joint and make it prone to cracking. Contaminants like oil, dirt, or moisture on the surface are common causes.
To prevent porosity, clean the metal thoroughly before welding. Use solvents like acetone for effective cleaning. Proper storage of electrodes also reduces the risk of moisture contamination.
Weld Undercut and Its Impacts
Undercut happens when the weld metal doesn’t fill the groove completely, leaving a gap along the edges. This mistake creates stress concentrators, increasing the risk of cracks. Incorrect machine settings or improper torch angle often cause undercut.
To avoid undercut, maintain consistent speed and angle during welding. Adjust amperage and voltage settings to match the material thickness.
