    There are lots of riveted steel fireboxes out there but there are a growing number of welded steel fireboxes. The problem with a riveted box is it requires lap joints and that is a weak spot compared with a welded box because there is a greater thickness of metal at that place and that makes the surface on the fire side further away from the cooling boiler water and there is a tendency for it to degrade over time. That’s the same whether it’s steel or copper.
    I’m surprised that welded copper boxes are few and far between. I only know of two in the UK, both on Danish locos.
