The economic breakpoint for section thickness using these three routes is a matter for some
conjecture but, as a rule of thumb, one would use solid plate up to 10 mm, above this roll
bonded material up to 35 mm total thickness. Explosive bonding is common above 35 mm and
weld overlay is the preferred method at thicknesses greater than 100 mm. Normally, the
cladding thickness is 1.5 mm minimum, 2 - 3 mm is most common; heavier deposits are rarely
encountered except as explosively bonded tube plates or weld overlayed components.
