Buttering in dissimilar weld is used to control carbon migration and diffusion across boundary. Does it have any negative impact too on the weld performance ?
Thank You Kulwant Singh Sir. These articles definitely give an insight into effect of buttering layer. I am specifically looking for demerits/adverse effects of buttering on dissimilar weld (if any) specially for marine application welds.
Krishnan Raja Sir, Thank you so much for the specific answer.
Will buttering in welds with marine application tend to increase the galvanic corrosion ? If so, then can you please recommend a specific literature regarding the phenomenon, cause or its mechanism.
