Hi all,
Are there any problems with welding SS 304 to SS 304L? The weld in question is between two 3'' Sch 40S pipes.
Thanks.

250 deg F to avoid any more heat input as necessary for 304 stainless steel.

What about an interpass temp of 350 deg F? That is what I have most commonly seen and approved.

There is no reason to weld with anything other than 304L filler, unless the weld must have some special properties.
