Euro socket, and yes it looks like they spot welded them ( poorly) then put the hot snot to hold the pieces together so the little flakes of CCA that will invariably fall off the plated steel ( brass is expensive, so just brass plate it, she'll be all right) will still not fall out of the plastic housing.The 2 halves of the conductor strip are not spot welded together, that looks more like a formed rivet in the metal, a mechanical fastener.
Amazing is that the cable conductors actually are the right number of strands, and the PE is the same number of strands, I regularly see that the PE is half the metal and twice the plastic ( guess which is cheaper) in cables.
Yes the modern made stuff, even from reputable manufacturers who have an established name for quality products, is now a lot poorer, with the material being thinner, the rating being nominally the same but in real life they do not meet this. If I try drawing 16A ( the rated current in S Africa) from a modern outlet plate, using a cheap 16A rated plug, it will overheat and possibly catch fire. Outlet uses thin brass which loses spring after 5 insertion cycles, and the plug that goes in it uses a plated hollow steel pin with stamped wire terminals, not the old one which uses a brass stamping with a backing spring steel collet to ensure contact, and the plug has solid brass pins with a cut thread for the wire holding screw.
