Welded bracket — fillet + V-groove callouts

AWS A2.4 welding callouts on a fabrication drawing — an intermittent double-fillet bracket with a weld-all-around flag, and a full-penetration V-groove butt weld with backing, root opening, and the welding process in the tail.

What this shows

A welding symbol is the standard way a drawing tells a fabricator how to weld a joint — codified by AWS A2.4 (US) and ISO 2553 (international). It is a reference-line skeleton: a horizontal line, a leader arrow to the joint, and a weld glyph snapped above (other side) or below (arrow side) the line, with dimensions in fixed slots.

The first joint is an intermittent double fillet — a size=8 arrow-side fillet welded 50 long on a 150 pitch, a size=6 fillet on the other side — carried all around the gusset (the open circle at the leader junction) as a field weld (the flag), with the GMAW process noted in the tail. The second joint is a full-penetration V-groove butt weld: a 60° included angle with a 3 mm root opening and a 12 mm effective throat, a backing weld on the far side, ground flush, welded SMAW with E7018 electrode. Each callout is placed correct-by-construction — the engine owns the skeleton, you describe the weld.
