Weld symbols are often used among welders and engineers. Learn how to read common welding symbols and their meaning. Common weld symbols and their meanings When welds are specified on engineering and fabrication drawings, a cryptic set of symbols is used as a sort of shorthand for describing the type of weld, its size and other processing and finishing information. Here we will introduce you to the common symbols and their meaning. The structure of the welding symbol The horizontal line — called the reference line — is the anchor to which all the other welding symbols are tied.

"Burn Through" Definition - Welding, Bonding & Fastener engineering - Eng-Tips
Castings are a product form that often receive radiographic inspection since many of the defects produced by the casting process are volumetric in nature, and are thus relatively easy to detect with this method. These discontinuities of course, are related to casting process deficiencies, which, if properly understood, can lead to accurate accept-reject decisions as well as to suitable corrective measures. Since different types and sizes of defects have different effects of the performance of the casting, it is important that the radiographer is able to identify the type and size of the defects. ASTM E, Standard for Radiographs of castings has been produced to help the radiographer make a better assessment of the defects found in components.

I don't see anything in the post referencing backing. This would be unusual for PJP welds, as the base metal usually acts as backing for these welds. Also, burn-through on backing material would be considered to demonstrate excessive penetration, not lack of fusion. DeanS, The key question to any inspection interpretation question is - which specification being used to reject the part?
Full penetration Weld and Weld symbol Question from reader "Whats a full penetration weld? And whats the welding symbol to use for a full penetration weldment? Answer This is a pretty common question and there is no way to answer it without some pictures. Hopefully this page will shed some light on the subject. A full or complete penetration weld can be a really thick weld that has been beveled and then penetrated by being filled with multiple weld passes, or it could be a sheet metal joint that is.
