Fillet weld size for clad material
Fillet weld size for clad material
(OP)
I found the drawing indicates size of weld leg 9 mm. The joint is fillet weld of support bar on the clad material. However, clad thickness is only 3 mm.
Are there any problems to size the fillet weld greater than the thickness of clad material? Please comment.

RE: Fillet weld size for clad material
The answer is no. It is probable that the designer wanted to assure fusion of the support bar to the base metal of the vessel for strength purposes. Fillet welds are sized for strength as a function of base metal thickness. Cladding is treated like a barrier coating and cannot be taken credit for strength like a weld overlay that is fused with the base metal.
Make sure the support bar fillet weld deposit is cladded to assure corrosion protection in service.
