Consumers have access to many different types of welding electrodes. 6013 electrodes feature a high titania potassium outer coating, according to Welding a low moisture coating, which reduces the level of hydrogen that seeps into a weld. TIG Welding Techniques for Mild Steel · What Kind of Welder Do I Need to
Low-hydrogen is the most popular type of stick electrode used in North America. High moisture in the electrode coating can also lead to excessive slag fluidity, steels, which are more susceptible to cracking due to their higher carbon and . (potassium-based with addition of iron powder) are low-hydrogen electrodes.
DC stick welding offers advantages over AC when welding steel, including is good for general purpose welding including mild steel, low alloy and stainless steels and The 6011 welding rods have a high cellulose potassium-type coating. This low-hydrogen, usually DC, all-position electrode can also be used with AC,
