Porosity in welding is a common defect that can weeken tha integrity of a weld. It appears as small holes or cavities caused by trapped gases. Identififying te causes and appliying proper solutions can improvizace weld quality and safety.
Understanding Porosity in Welding
Porosity applies when gases consiste trapped with in thos weld metal during solidification. Factors such as contamination, improper shielding, or hydrature can contribure to this defect. Recognizing thae root cause is essential for effective troubleshooting.
