Presentation on theme: "ASME P Material Numbers Explained"— Presentation transcript:
1 ASME P Material Numbers Explained ASME has adopted their own designation for welding processes, which are very different from the ISO definitions adopted by EN DesignationDescriptionOFWOxyfuel Gas WeldingSMAWShielded Metal Arc Welding (MMA)SAWSubmerged Arc WeldingGMAWGas Metal Arc Welding (MIG/MAG)FCAWFlux Cored WireGTAWGas Tungsten Arc Welding (TIG)PAWPlasma Arc WeldingStraight polarity = Electrode -veReverse polarity = Electrode +ve
2 ASME F Numbers F NumberGeneral Description1Heavy rutile coated iron powder electrodes :- A5.1 : E70242Most Rutile consumables such as :- A5.1 : E60133Cellulosic electrodes such as :- A5.1 : E60114Basic coated electrodes such as : A5.1 : E7016 and E70185High alloy austenitic stainless steel and duplex :- A5.4 : E316L-166Any steel solid or cored wire (with flux or metal)2XAluminium and its alloys3XCopper and its alloys4XNickel alloys5XTitanium6XZirconium7XHard Facing OverlayNote:- X represents any number 0 to 9
3 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. A1Plain unalloyed carbon manganese steels.A2 to A4Low alloy steels containing Moly and Chrome MolyA8Austenitic stainless steels such as type 316.
4 ASME Welding Positions Note the welding progression, (vertically upwards or downwards), must always be stated and it is an essential variable for both procedures and performance qualifications.

13 Welding Positions QW431.1 and QW461.2 Basically there are three inclinations involved.Flat, which includes from 0 to 15 degrees inclinationdegrees inclinationVertical, degreesFor each of these inclinations the weld can be rotated from the flat position to Horizontal to overhead.
