    All types of welding rely on some form of protection to keep the weld puddle from oxidizing. Molten metal has an afinity to oxygen. Some processes use an inert gas ( ie:GTAW GMAW) the G, being Gas, is usually argon,helium, or CO2. SMAW (stick welding) S being Shielded, uses both slag and smoke to protect the molten puddle. Therefore it stands to reason if the wind is strong enough to blow away the smoke or inert gas then oxygen contained in the air can attack and destroy the weld.
