Weld all around Field weld

AWS A2.4 convention: arrow-side info is BELOW the reference line, other-side info ABOVE. This is an interpretation / detailing aid only - not a substitute for the contract weld spec, the EOR, or AWS D1.1. Symbols shown: fillet, V-groove, bevel, square groove.

Weld Symbol Builder & Reader

Build a weld symbol from its parts, or turn a symbol back into plain English. Pick the weld type and size for each side, add all-around, field-weld, contour, length, and pitch - the symbol updates live and reads itself back, so you can sanity-check what an engineer's callout actually means.

Everything here is a detailing and interpretation aid. It does not replace the contract weld specification, the engineer of record, or AWS D1.1 - always verify against the project documents.
