Basically the electrode should match the base metal. 308 or 308L for 308 stainless steel.

What is the welding procedure for welding P22 pipe to 304 stainless pipe?

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.


What metal is used to make screws?

Any metal that isn't too soft can be used. Stainless steel, regular steels, brass. Even aluminium. Titanium can be used as well.


Will aluminum contaminate stainless steel if used together?

No. Stainless Steel will resist contamination from the aluminum when they are used together.


What type of metal is a door handle made of?

Brass, aluminium, stainless steel, cast iron, wood, Bakelite, plastic and other materials have all been used to make door handles. The mechanism is usually made from brass, steel or stainless steel.


Which electrode is used to weld stainless steel to carbon steel?

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.
