[MW:1899] Re: Multi layer weld capping in SAW

Hi,
 
As per my awareness, multi layer caping in SAW to improve the toughness by way of inceasing the Volume fractin of the Accicular Ferrite in weld metal, and to avoid the over tempering of weld bead.
 
Thanks and regards,

Gents,

 

Does anybody knows why multi layer weld capping, especially in sub arc welding, is preferred than single capping weld? Is there any metallurgical affect due to dilution in single layer weld capping?
