Difference between 7018 and 6013 electrodes?

6013 is normal arc electrode which is used for light jobs like sheet welding or tank

making but when it comes to heavy construction jobs where strength required

is more 7018(Low Hydrogen) Arc Electrode is used like boilers, heavy structures

etc. Working with 6013 is far easier than 7018, which requires welder's skills.

Neatness in finishing is also more with 6013 than 7018.
