309 stainless steel welding rod used to MS to SS 308 stainless steel welding rod only used to SS
308 is considered an all around rod for stainless steel. But not recommended for food grade stainless. 309 is usually used when welding carbon steel to stainless steel.
The most common types of rods used for welding stainless steel are 308, 309, and 316. 308 rods are best for welding 304 stainless steel, while 309 rods are recommended for welding 309 stainless steel. 316 rods are suitable for welding 316 stainless steel and are also good for general-purpose welding of higher-grade stainless steels.

We were told 309 was the electrode of choice.
During the reign of Constantine I (the Great, 306-337) the popes were: Marcellus I (308-309), Eusebius (309-310) Miltiades (311-314), Sylvester I (314-335), Mark (330), and Julius I (337-352). Between 304 and 308 there was an interregnum, a period where there was not a pope.
The difference between 309 and 132 is 177 numbers.
It depends on the type of stainless steel. Stainless steels come in various compositions and are identified by numbers and letters. Electrodes should be chosen that match these. For example when welding 316 stainless use type 316 electrodes. In a lot of situations you can safely use the next higher number. 304 stainless can be welded with 308 electrodes, 308 stainless with 310 electrodes. 309 electrodes are generally used to weld stainless to carbon steel.

I have not welded P22, but from what I read it is a low allow stainless that tends to get brittle. The welding techniques specified include a pre and post heat treat and on thicker materials a buffer layer of 316L with the final joint of 309 not sure what p22 pipe is but if it is carbon you should use a 308L filler with 100% argon purge 308L is a filler for fusing carbon steel and non carbon stainless. If it were 316 stainless you would want to use a 319 filler P22 is a steel alloy containing 2 1/4% chromium. It is weldable with most carbon steel alloy fillers such as E-70s2, ER-7018, etc. However, to weld it to a low grade stainless steel alloy such as 304, you would need to use a bi-metal welding alloy such as E-309, or ER-309. The above answer is incorrect regarding 308L being a filler for carbon steel to stainless steel. It is in fact 309 which is used for dissimilar metal welding when one component is stainless steel. I have also had good success welding two dissimilar metals together using inconel alloy welding electrodes such as INCO-182.

multiplying? 2*155 10*31 adding 309 and 1 308 and 2 etc subtracting 311-1 312-2 etc
