What is blowhole or piping welds defect?
Blowholes or piping in welds are defects characterized by the presence of small voids or cavities within the weld metal. These defects occur when gases, such as hydrogen, nitrogen, or oxygen, become trapped in the weld pool during solidification. Blowholes or piping can compromise the structural integrity and mechanical properties of the weld, leading to potential issues such as reduced […]
