Bandsaw blades are welded at the factory, the welds are fine.
Many large industrial bandsaws come with a blade welder mounted on the saw frame. This allows for making inside cuts on a large workpiece. Cut the blade, insert one end through a hole in the workpiece, weld blade back together, make cut in workpiece, cut blade again to free workpiece.
Good blade welders allow you to weld the blade, anneal it to remove the brittleness caused by welding, and grind it smooth again.
Of course, if the blade breaks during usage because you twisted it too much, you can weld it back together.
Some shops with lots of bandsaws, rather than buying pre-made blades, buy large rolls of blade material (teeth already cut), and just make their own blades to length.
It tells you about the blade shear (to get square cuts on the blade ends), the welder station which also does the annealing, and the grinder. Follow the directions for use and you should be good. Just be sure you don't have the blade twisted when you clamp it in the welding station.
