ASME P Material Numbers Explained ASME has adopted their own designation for welding processes, which are very different from the ISO definitions adopted by EN24063. Designation OFW SMAW SAW GMAW FCAW GTAW PAW Description Oxyfuel Gas Welding Shielded Metal Arc Welding (MMA) Submerged Arc Welding Gas Metal Arc Welding (MIG/MAG) Flux Cored Wire Gas Tungsten Arc Welding (TIG) Plasma Arc Welding

Note:- X represents any number 0 to 9

ASME A Numbers These refer to the chemical analysis of the deposited weld and not the parent material. They only apply to welding procedures in steel materials. A1 A2 to A4 A8 Plain unalloyed carbon manganese steels. Low alloy steels containing Moly and Chrome Moly Austenitic stainless steels such as type 316.

ASME Welding Positions Graphic Representation Note the welding progression, (vertically upwards or downwards), must always be stated and it is an essential variable for both procedures and performance qualifications. Welding Positions For Groove welds:Welding Position Flat Horizontal Vertical Upwards Progression Vertical Downwards Progression Overhead Pipe Fixed Horizontal Pipe Fixed @ 45 degrees Upwards Pipe Fixed @ 45 degrees Downwards Welding Positions For Fillet welds:Welding Position Flat (Weld flat joint at 45 degrees) Horizontal Horizontal Rotated Vertical Upwards Progression Vertical Downwards Progression Overhead Pipe Fixed Horizontal Welding Positions QW431.1 and QW461.2

Basically there are three inclinations involved. Flat, which includes from 0 to 15 degrees inclination 15 - 80 degrees inclination Vertical, 80 - 90 degrees For each of these inclinations the weld can be rotated from the flat position to Horizontal to overhead.
