Are you talking pipe welding ? Schedule 40 / 80 ? If it is 40 , two stringers and a weave cap is ok. If doing 80 , all stringers . I like stringers because there is better control and less movement. With a weave all you need to do is cover the last and burn into the sides.

What does schedule have to do with your technique? If its 80 you could weave a fill and cap the same as 40, if its 5g....2g and 6g stringers no matter what schedule. If its 160 or XX you might need to weave two stringers, this aint nothing new baby, lol.

For me on 40 just two passes and a cap. On 80, I don't like weaving and prefer stringers. I would rather use four stringers to fill instead of two weaves. I just like stringers.
