Which welding process uses no electricity and is not sensitive to wind or drafts?

Explanation:
Gas welding uses a flame produced by burning a fuel gas with oxygen, so no electricity is needed to generate the heat. Because there’s no electric arc and no shielding gas that can be blown away by drafts, this method is less sensitive to wind or drafts than arc welding processes. The other methods rely on an electric arc and typically require shielding gas or protective slag; wind or drafts can disturb that protective environment and degrade weld quality. So the option that uses no electricity and is comparatively less affected by wind is gas welding.
