Symbols for indicating welded joints on engineering drawings were
originally devised by individual drawing offices to provide more
useful information than a simple arrow with the instruction ‘weld
here’. This practice was obviously unsatisfactory, especially when
drawings were passed from one company to another and, to solve
this problem, the numerous symbols in existence were rationalised
to some extent by countries compiling their own standard specifications
for welding symbols.
