HOBART
Frequently asked questions
Common questions about HOBART from 3G Electric.
What are the as-welded mechanical properties of Hobart ER316L TIG welding rods?
Hobart ER316L TIG welding rods, such as SKU 54JK88 and 54JK89, have an as-welded yield strength of 58 ksi and a tensile strength of 86 ksi. These rods are classified as ER316/316L and are suitable for joining low-carbon 316L stainless steels. They are supplied in 10 lb packages and are available in diameters including 1/8 in and 3/32 in, with lengths of 36 in. The low-carbon content helps resist intergranular corrosion in welded joints.
What sizes and packages are available for Hobart E308 stick welding electrodes?
Hobart E308 stick welding electrodes are available in multiple sizes and package weights. For example, SKU 54JK85 is a 3/32 in x 12 in electrode in a 5 lb container, while SKU 33M409 is a 1/8 in x 14 in electrode in a 10 lb package. Both are classified as E308/308L-16 and have an as-welded yield strength of 54 ksi and tensile strength of 83-84 ksi. These electrodes are used for welding 304 and 308 stainless steels.
What is the AWS classification for Hobart ER308 MIG welding wire?
Hobart ER308 MIG welding wire, such as SKU 54JK70, is classified as ER308/308L. It is supplied on a 10 lb spool with a 0.03 in diameter. The as-welded yield strength is 59 ksi and tensile strength is 85 ksi. This wire is suitable for welding 304 and 304L stainless steels in applications where corrosion resistance is required. The ER308/308L classification indicates it can be used for both 308 and 308L base metals.
What are the typical applications for Hobart E316L stick welding electrodes?
Hobart E316L stick welding electrodes, such as SKU 54JK87 and 33M413, are used for shielded metal arc welding (SMAW) of 316L stainless steels. They are suitable for applications requiring corrosion-resistant welds, including chemical processing equipment, food processing machinery, and pharmaceutical piping. The electrodes have an as-welded yield strength of 56 ksi and tensile strengths of 80.6-82 ksi. They are available in sizes like 3/32 in x 12 in and 1/8 in x 14 in, in 10 lb packages.
What is the difference between Hobart ER316 and ER316L MIG welding wire?
Hobart ER316 and ER316L MIG welding wire differ primarily in carbon content. ER316L has a lower carbon content (0.03% max) compared to ER316 (0.08% max), which reduces the risk of intergranular corrosion in welded joints. Both are classified under ER316/316L and have similar mechanical properties: as-welded yield strength of 58 ksi and tensile strength of 86 ksi. The low-carbon version is preferred for applications involving corrosive environments or where post-weld heat treatment is not possible.
What package sizes are available for Hobart ER316 MIG welding wire?
Hobart ER316 MIG welding wire, such as SKU 54JK73, is supplied on a 30 lb spool with a 0.035 in diameter. It is classified as ER316/316L and has an as-welded yield strength of 58 ksi and tensile strength of 86 ksi. This wire is used for welding 316 and 316L stainless steels in applications requiring corrosion resistance. The 30 lb spool is suitable for larger welding projects where extended run times are needed.
