Provides chemical composition and mechanical property data for a collection of all weld metal deposits.

The file welddb.tar contains three files. File welddb.data contains the chemical composition of the steels studied, and their room temperature mechanical properties. These data have been collated from available literature. The presence of an `N' indicates that the value was not reported in the publication. This is NOT meant to be an indication that the value is zero. Although many columns are presented here, those which only have a small amount of data have been removed for the analysis described in [1 and 2]. This enabled more input lines to be used for neural network analysis.

Files welddb.info and welddb.tex contain, respectively, text and plain TeX versions of this documentation.

Data are arranged as follows :-

Column 1 is Carbon concentration / (weight%)

Column 2 is Silicon concentration / (weight%)

Column 3 is Manganese concentration / (weight%)

Column 4 is Sulphur concentration / (weight%)

Column 5 is Phosphorus concentration / (weight%)

Column 6 is Nickel concentration / (weight%)

Column 7 is Chromium concentration / (weight%)

Column 8 is Molybdenum concentration / (weight%)

Column 9 is Vanadium concentration / (weight%)

Column 10 is Copper concentration / (weight%)

Column 11 is Cobalt concentration / (weight%)

Column 12 is Tungsten concentration / (weight%)

Column 13 is Oxygen concentration / parts per million by weight

Column 17 is Boron concentration / parts per million by weight

Column 18 is Niobium concentration / parts per million by weight

Column 19 is Tin concentration / parts per million by weight

Column 20 is Arsenic concentration / parts per million by weight

Column 21 is Antimony concentration / parts per million by weight

Column 22 is Current / A

Column 23 is Voltage / V
