Welding of Ferritic / Martensitic Stainless Steels - TWI

When this is associated with a weld it is often known as weld decay.Developments in recent years of extra low carbon,titanium or niobium containing grades have,however,improved this situation.The ferritic stainless steels are generally welded in thin sections.Most are less than 6mm in thickness where any loss of toughness is less significant.WELDING OF STAINLESS STEELS AND OTHERwelding characteristics of stainless steels,so they may exercise better control over the finished products with respect to welding.In addition to welding,other ancillary joining methods are discussed,including soldering and brazing.WELDING OF STAINLESS STEELS AND OTHERwelding characteristics of stainless steels,so they may exercise better control over the finished products with respect to welding.In addition to welding,other ancillary joining methods are discussed,including soldering and brazing.
