Requirements on hydrogen content of unalloyed and low-alloyed welding consumables

The hydrogen content should be lower than or equal to 5 ml of hydrogen per 100 g of weld metal when welding with unalloyed or low-alloyed welding consumables. Solid wire used in MAG/ GMA and TIG/ GTA welding can produce these low hydrogen contents in weld metal.

The hydrogen content for other types of welding consumables should be obtained from the respective manufacturers. SSAB provides examples of suitable consumables in TechSupport No. 60, together with other useful information available on our homepage: https://www.ssab.com/en/support/how-to-process/how-to-weld.

If consumables are stored in accordance with the manufacturer’s recommendations, the hydrogen content will be maintained to meet the requirement stated in the table below. This also applies to all coated consumables and fluxes.
