Here are the welds I'll be basing mine on..
I've mostly found attached parts have a rough fillet
welded plates have a leveled/rough fill with minor gaps or a slight divot. At least based on the era I want to represent.
Started on the groundwork. Here's one very exciting bollard
I used the ID code on the bollard as my signature.
Made from a till receipt roll middle, and half a Gustav hip joint.
