Just for a comparison, here is the drum seam from my parents Hotpoint WF541 that has the recently phased out Hotpoint drum:

... and here is a pic of our Hoover's drum seam that will have the same kind of seam on the Hoover/Candy machines that exploded. I checked today and the Indesit drum now fitted to Hotpoints also has this kind of seam:
Don"t see any price change tbh..
As far as I can see, the WT541"s drum is screwed, and Hoover is the welded?(aswell as the new indesits?)
But it doesn"t seem that screwing is more expencive than welding? Is there sth I misunderstood?
thanks 4 such a proffesional reply! and Happy new year!!

Welds
Using a few screws would probably be cheaper than welding is my guess. Since 201 stainless is quite "springy" aligning the holes could be not easy. With a decent weld there is one long strong joint. Welding is used with piping, custom stainless ducts in many industries.
In a consumer product, production cost is a massive concern. Thus one might have a crimped joint and just a few tack welds or few screws. In design reviews, wringing out (reducing ) costs matter. Designs are changed to save a few cents. ( 1/100 of a dollar ). If 1 million units are made, saving 5 cents is 50000 dollars. There are folks whose job is to just lower the cost.
As the rpm increases, the design has to be better to have this joint not fail.
