If you are not sure about which electrode to use for a particular grade of steel make sure to ask a professional or the manufacturers recommendation.
Welding stainless steel electrode. It is typically used to make welding electrodes and used to join common types of austenitic stainless steels such as 301 302 304 and 305. WELDING OF STAINLESS STEELS 10 INTRODUCTION Stainless steels are defined as iron base alloys which contain at least 105 chromium. They might not be able to weld but they sure know what products to choose and why.
Regarding your second question 308 is a particular type of stainless steel. If you are welding a higher grade stainless you will then need to consider an ER 316L electrode. SMAW - Shielded Metal Arc Welding or Stick Electrode.
The ER 309L electrode is pretty difficult to weld with and it produces a rough looking weld. Suitable for welding stainless steel tanks valves pipes and linings in chemical petrochemical energy food beverage pharmaceutical industries. The bottom line on selecting electrodes or filler wires is to ask you weld supplier on what to do.
In the United States welders mostly follow three methods for welding stainless steel ie. Basic coated electrode for welding austenitic stainless Cr-Ni steels or cast steels having an extra low carbon content as well as stainless or heat resisting chromium steels or cast steels. MIG metal inert gas welding is a semi-automatic welding type.
This process also uses shielding gas against contamination but you can weld thinner metals more efficiently with it. 308L including ER308LSi is predominately used on austenitic stainless steels such as types 301 302 304 305 and cast alloys CF-8 and CF-3. We provide an extensive range of SS electrodes such as 308L 309L and 316L.
Finally the ER 309L is for welding stainless steel to steel. You do need to use an E308H electrode. The thin but dense chromium oxide film which forms on the surface of a stainless steel provides corrosion resistance and prevents further oxidation.
SMAW is an electric arc welding process in which heat for welding is generated by an electric arc between a covered metal electrode and the base metal. Moreover what type of welding rod is used for stainless steel. Stainless Steel Welding ElectrodeEnquire Now.
Stainless steels are weldable materials and a welded joint can provide optimum corrosion resistance strength and fabrication econom y. It uses a continuous consumable solid wire electrode and an argon rich shielding gas for welds. Ad Find China Manufacturers Of Welding Electrode.
Why welding of stainless steel is. The three most common stainless welding processes are. The reason why will be explained shortly.
MIG welding TIG welding and Resistance Welding types. For high temperature applications such as in the electrical power industry the high carbon 308H electrode provides better creep resistance than does 308L. TIG welding stainless steel is performed by using a non-disposable tungsten electrode with a TIG welder for striking up the arc.
OK 6713 can also be used for welding certain air-hardening steels such as armour. Ad Find China Manufacturers Of Welding Electrode. It offers high cracking resistance and good strength and typically can join stainless steel already in service even if the specific material grade isnt known.
The main application is for welding austenitic stainless steel with the same analysis as the weld metal AISI 304 and can also be used for welding AISI 301 302 308 and equivalent grades used for hospital apparatus pharmaceuticals equipment apparatus for nitric acid acetic acid milk soap fertilizer industries. OK 6713 is an austenitic stainless-steel electrode for welding 25Cr20Ni steels. The weld metal resists scaling up to 1100-1150C and does not contain any measureable ferrite.
Stanvac-Superon group is a leading manufacturers and exporters of high quality stainless steel welding electrodes. In the fabrication of stainless steel products components or equipment manufacturers employ welding as the principal joining method.

SS 316 Welding Electrode. What electrode is used to weld stainless steel Stainless steel electrode can be divided into chromium stainless steel electrode and chromium nickel stainless steel electrode these two types of electrode in accordance with the national standard according to the national standard GBT983-2012 provisions of the assessment. The most important thing to keep in mind is choosing the right electrode for the job some of the most common electrodes recommended for welding stainless steel are 316 308 312 and 309.
There are five types of stainless steels depending on the other alloying. Stainless Steel MIG Welding.
