On the corner of Wood Lane and Uxbridge Road. The unusual pub name is thought to be derived from the fact that one of the "Cambridge five" Cold War spies worked nearby at the BBC and 'weld' is a joint/joining i.e. a coming together. Bought by Young's in 2014, the pub was last refurbished in late 2023 and now has an attractive glass-roofed courtyard.

On the ground floor is the large horseshoe-shaped main bar and a mix of banquettes, table and chairs. An upstairs room with a bar is available for hire. DJs play music Friday & Saturday evenings.

A Young's cask ale plus one other (depending on demand) should be available, and a wide food menu includes vegetarian and vegan dishes and Sunday roasts.
