I have a question about these two connection type. Which is useful. Base material is H Profile, Flannge is 115mm thick and body is 79mm. It is using for tower project all perpendicular connection connected by weld. Root and hot done by 8018, fill and cap done by FCAW. We done all wps and pqr for these connection everything is ok. The question whic is better? At present progress goes on X connection.

Thanks to sharing knowledge
