Why does Boron, which is in the same group of aluminum, not form 6-coordination complexes like aluminum.I've got the answer but I don't see how it is right.Can someone please explain?Thanks.
This also depends upon the type and quality of the weldsIf the welding was done by an experienced welder who works with aluminum the welds will be stronger than if the welds are done by an experienced welder who does not work with aluminumAluminum welding is a specialized trade.
I'm no engineer so can't specify strengths but, typically welds are held to be stronger than the than the components that they holdWorking with high pressure gases in welded stainless steel tubing I have never seen a weld give way although I have seen a tube rupture.
The previous posters are mistaken The weakest part of any weld is in the Heat Affected Zone (H.A.Z.) around the weld, not the weld itselfThis is especially true with aluminumT Note: The -T6 suffix after 6061 indicates heat treated material Welds on heat treated Al alloys like 6061 series can be expected to be SIGNIFICANTLY WEAKER than the parent metal The heat of welding destroys the heat treatment in the H.A.Zand may result in greater than 60% loss of strength there Welds on aluminum are also notoriously prone to cracks, unlike steelsThe reasons for this are complex and don't bear discussionI'm not sure I understand what you mean by overlapping above and overlapping belowI can't really give you an idea how strong the joints would be unless you're much more specific Are you talking about simply laying the pipes on top of one another and depositing a small amount of weld around the contact point? That's a bad ideaYou'd have a far stronger joint by drilling a hole through both pipes and bolting them together in that configuration.
The essential conditions required for the formation of complexes are 1)High/moderate electronegativity 2)Vacant d or f orbitals 3)small size and moderately high charge density B satisfies13 but not 2 which is very much essential for it accept electron pairs.
