AWS D10.18M/D10.18

This standard provides a summary of recommended industrial practices for welding piping¹ fabricated from aluminum alloys. Joint design, welding current, and shielding gas tables are included. This standard makes use of both the International System of Units (SI) and U.S. Customary Units. The measurements may not be exact equivalents; therefore, each system must be used independently of the other without combining in any way. The standard with the designation D10.7M:2000 uses SI Units. The standard designation D10.7:2000 uses U.S. Customary Units. The latter are shown within parenthesis ( ) or in appropriate columns in tables and figures. Pipe sizes are listed as DN (diameter nominal) and NPS (nominal pipe size). The exact pipe diameters are listed in Table 13.

1. The terms pipe and piping in this standard are intended to include tube and tubing where appropriate.
