OE on carbon steel welding rod indicates the rod, the first two digits represent the minimum tensile strength of the deposited metal, the third digit represents the welding position, and the combination of the third and fourth digits represents the type of welding current and the type of coating.
For stainless steel welding rods, E represents the rod, the numbers after “E” represent the chemical composition classification code of the deposited metal, and the two digits after “-” represent the type of coating, welding position and type of welding. welding current.
For more details, you can refer to GB5117 and GB983.
