We were told 309 was the electrode of choice.
dissimilar steel grades and the unknown grade ss can easily welded with the help of 680CGS lnt welding electrode

This would depend on several variable such as: Welding process being used (SMAW, GMAW, etc). Specific type and grade of the Stainless Steel. The required tensile strength, ductility, and corrosion resistance. If you are welding pressure piping, the applicable ASME codes have a table in section IX. AWS D1.6 addresses structural applications. There are three basic types of Stainless Steels. Austenitic, Martensitic, and ferritic. Each has characteristics that differ from each other in the post welded condition. For a good selection of electrodes and their applications, your local welding supplier should have free reference books by various suppliers that will help. These are the same books we us to assist us in developing welding procedures to various codes and standards.
M.S. = mild steel S.S. = stainless steel
The answer is "YES". ASME IX allows a welder qualified on base metal P(or S) number 1 to 11 to weld P1 to 11. Please refer to ASME IX QW-423. Hope this helps. Sun.

309 stainless steel welding rod used to MS to SS 308 stainless steel welding rod only used to SS

SS - steamship; MS - motor ship.
It probably can be used. SS is Steel with Chromium and Nickel added BUT it will not be corrosive resistant & will not match the SS in color or strength. It would be like gluing a piece of Pine wood to a piece of Mahogany.

The best way to successfully weld SS to MS or even Hardened Tool steel to MS is to use Magna 303 welding rod mfg by Magna Industrial, Australia. It has been tried and tested and is the only successful way to weld different steels and the weld has a tensile strength of 1,20000 psi, but these rods are expensive and suitable primarily for maintanence or repair welding
Yes. There are covered electrodes made for SMAW (stick) welding of SS. I have actually repaired one of my wifes SS cooking pots that had a broken handle with a stick welder.

during the welding of any pipes, pressure parts,ms to ss welds-energy/load/frequency/current needs to be constant rather than fluctating which will affect the weld deposition with in the gap which will lead to weld porosity. Rectrifire eliminates the above
