Hallock Campbell AWS definition dispute

Hallock Campbell (Harvard grad, AWS glossary author) wrote to Tom in Japan in 1985 critiquing his use of "parameter" in a Welding Journal title. Tom showed the dictionary cited Bridgman; Campbell's handwritten reply: "Percy, how could you?" Used as launchpad for Tom's "weld defined by properties, not process" reformulation in his keynote address.

The paper I wrote was called "In Search of the Perfect Weld." I started by taking the AWS definition from their glossary: a weld is "a localized coalescence of metals or non-metals produced by either heating the materials to the welding temperature with or without the application of pressure, or by the application of pressure alone, and with or without the use of filler metal." If you analyze that, what you get is: a weld is something that can be metal or non-metal, can have temperature or not, can have pressure or not, and can have filler metal or not. Isn't that a great definition?
