Is it fully welded?
Thread Content
1. There are two common types of welds used for the skirt and head, as shown in the attached drawings; which of these two configurations achieves full penetration? Is it still not considered fully welded? Why? 2. In HG/T20583-2011, do G1 and G23 in the weld structure table represent fully penetrated structures? Why?
In my personal opinion, all of these 4 structures are considered full-penetration structures.
The original poster is really thorough, waiting patiently for an answer; but it seems that complete welding shouldn’t be avoided
The first two are equipment welding methods, which fall under full penetration welding； The last two are fillet welds in the structure that are not fully penetrated
Agree with the explanation on floor 4; the last two probably weren’t welded thoroughly, while the one at the skirt base should have been welded thoroughly.
a refers to the welding method of the equipment, and it belongs to the through-welding type； G1 and G23 are fillet welds in the structure that are not fully penetrated.
Personally, I think full penetration isn’t necessarily guaranteed; it depends on the dimensions of the structural material
1. Whether the skirt connection is made by butt welding or lap welding, it is always a fully welded-through structure; this is clearly stated on page 19 of the standards for tower-type containers, where it is mentioned that the connection is fully welded-through. 2. Neither G1 nor G23 is a \"fully welded-through structure\""
