What is the difference between full penetration and full cross-sectional penetration?
Thread Content
As the title suggests: Are full penetration and full cross-section penetration the same thing? What’s the difference?
Full penetration means that the deposited metal has the same thickness as the plate. A fully penetrated structure is a groove type that ensures full penetration of the weld joint; it is a groove type that facilitates double-sided welding or welding equivalent to double-sided welding.

For example, in the case of butt welding and thick plate insertion welding, what does full penetration mean?
The nozzle is inserted into the plate, and the gap between the openings in the plate and the nozzle is filled. For welded structures, refer to GB150 and HG/T20583
Is the groove too large? Is it really necessary?
