Tbh its personal preference ive done like this ive done the way in my pics ive done bigger criss crosses wider ones stringer beads it doesnt really make a difference the main thing is it is done to the spec and passes xray which they do and thats what the guy paying the wages wantsheres how it should look not like a good year tractor tyre tread

My weave doesnt exceed 3 times the diameter of the wire . The pic you have shown is large pipe probably heavy schedule and therefore requires alot of filling passes and requires a three bead stringer . I can assure you my single cap beads are no wider than any of the stringers in your pic . The pipe used on my pics is 5 mm wall thickness you basically get away with root hot pass and cap .using a 3.2 mm tig wire a one bead cap is perfectly within the realms . I have stated in previous post this procedure is quite lax as it is heating water pipework running at 1.5 bar of pressure . Its not powerstation offshore steam or chemical hence the cheap blue band pipe . Next time i am doing some higher spec work i will take photos of the heavier shedules with stringers and updatewhat spec are you working to max weave usualy 3 x wire diameter , split cap = FASTER TRAVEL = less heat input thats all
no doubt be ok on the bomb il give you 9 outa,10

Thanks . There was no high frequency or foot pedal used .these welds where done with a cheap scratch start inverter . We only use high frequency when the spec is higher due to tungsten inclusion and even then it would be button start with no foot pedalA 10 out of 10 in my book, would be a cap that doesnt flatten out around the top part, welded in position without a footpedal
Must say though, very noice job done of those
