Welding Rod Used For Carbon Steel. The 33 rod is ideal for welding HSLA steels and AR plates to themselves or in dissimilar combinations where good ductility is desired even at low temperatures. So if youre planning on welding really old cast iron steel alloys remain your best bet for exceptional results.
A group of electrodes known as the low-hydrogen welding rods is also recognized by welding pedagogues as the fourth group of welding rods. For high temperature applications such as in the electrical power industry the high carbon 308H electrode provides better creep resistance than does 308L. However in some cases when welding to alloy steels the 29-9 nickel is sometimes used.
We Offer Specialized Welding Solutions in ER2594 ER2209 2205 DSS 2507 Duplex SDSS.
Stainless steel electrodes can also be used for welding manganese steels and for welding them to carbon and low-alloy steels. It is the most popular electrode for 50kgmm2 class high tensile steel. A group of electrodes known as the low-hydrogen welding rods is also recognized by welding pedagogues as the fourth group of welding rods. The E6012 electrode is used for welding thin sheet metal such as window frames metal furniture automobiles rolling stock freight cars and ships.
