Welding All Around Symbol Meaning. As a reference take a look at Figure 8 of AWS A242012 Standard Symbols for Welding Brazing and Nondestructive Examinations. Weld all around example.
The weld-all-around symbol also indicates welds completely around a joint in which the metal intersections at the welding points are in more than one plane. Field welds are welds not made in a shop or at the place of initial construction and are indicated using the field weld symbol fig. Welds completely around a joint in which the metal intersections at the points of welding are in more than one plane are also indicated by the weld-all-around symbol.
The all the way around symbol does not imply the weld is circular.
There is some confusion at my office as to the definition of the all around weld symbol. It could also be a matter of making sure the pontoon is sealed where it all comes together where as the double sided fillet weld would not accomplish that. There is some confusion at my office as to the definition of the all around weld symbol. I would argue the welding symbol isnt correct because you cant weld all around the clipped corners.
