RE: Welding Stainless Steel

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I was at an AWS seminar last year that dealt with welding of stainless steel. They passed out a booklet by Lincoln Electric that had a table of recommended filler metals. For type 304L stainless steel, they recommended E308L or E347 coated electrode, ER308L or ER347 for solid metal core wire, E308LT-X or E347T-X for flux core wire.

Table 3.2 of AWS D1.6:1999 lists 304L stainless in Base Metal Group A.  Table 3.3 indicates that the prequalified filler metal from AWS A5.9 for Base Metal Group A is ER316L.  An older publication, AWS D10.4-86, Table 4, lists ER316L for welding 316L stainless Base Metal only, but for 304L stainless Base Metal, it lists ER308 or ER347.  Is there any reason to pay attention to the old AWS D10.4?


Have there been important revisions into AWS D1.6 that call for the structural designer to get the latest edition?
