Hello all
when i weld 3 mm fillet weld lap joint , how many layers should i do ? i guess it would be only 1 layer but a welder told me that it would be 2 layers first root and cap
and i would like to ask what is the maximum gap of fillet weld lap joint between the two materials to be welded
thank you
Hello
thank you all for this helpful information it really helped me , and i would like to inform you that the welder welded this lap joint with first pass only with electrode diameter of 2.5 mm and the electrode is E7018 , and the weld is accepted.
Now i have another question , it may looks like i'm not have the enough experience , the welder welded first pass for butt weld with electrode E7018 and the second pass he started to weld it with Electrode E6013 , i told him not to and he should have brought E7018 and then weld it , he told me it's ok and this won't affect the metallurgy of the weld so i told him ok and weld , so he welded the second pass with E6013 as the butt weld was two passes , the root pass E7018 and the cap was E6013 , is that possible or not ?
Thank you all again
