Why is it important not to weld when everything is wet?

Welding in wet conditions is dangerous because moisture can lead to electrical hazards, increasing the risk of electric shock. Additionally, water can contaminate the weld, causing defects like porosity and weak joints. Wet surfaces can also hinder the proper fusion of metals, resulting in compromised structural integrity. For these reasons, it's crucial to ensure that the work area and materials are dry before welding.
