One can have Multiple Reference Lines as well as Multiple
"Weld" Symbols that make up the overall
welding symbol... In other words, a
weld symbol will represent the type of joint to be
welded together where the two members meet or a surface to be built up as in overlays & repairs... Whether it be an edge, fillet, groove, plug, projection, seam, slot, spot, stud, surfacing... All of these are names for
"Weld" Symbols... They are not
welding symbols because, the latter represents the reference line, arrow,
weld symbol, contour & finish symbols, and included with these
weld symbols also, may or may not be any of the supplementary symbols, dimensions & numbers, tail if any, field &
weld all around symbols, and any other details and/or reference(s) that make up the
"Welding" symbol... One only has to look in, or refer to: AWS A2.4 and look in the table of contents where there should be two or three listings numbered: 3.5 "Combined
Weld symbols"
3.6 "Multiple arrow lines" and 3.7 "Multiple reference lines" to read what is allowed and acceptable in creating the appropriate "Welding Symbol" for the parts and/or component/assemblies that require
welds to join together or build up.
cool::
Oh, and the version I referred to of A2.4 is 98 for
"Standard Symbols for Welding, Brazing and Nondestructive Examination" which was the only one I could find close by me... So if there are any changes or significant differences in the newer editions, please post them.
