Abstract

Incoloy 800 is a single phased, austenitic, solid solution alloy with fine dispersion of gamma prime particles and carbides. In general, this alloy lias good weldability and all the most common processes can be applied to it. With careful attention to edge preparation and fit up upto 8mm thick plates can be autogenously welded. This alloy is sensitive to segregation effects. It displays tendency to solidification cracking. There is some doubt about the susceptibility of this alloy to HAZ liquation cracking. Here the grain size plays an important role. This alloy can be welded either using high nickel fillers or matching composition filler materials. High heat-input welding processes like electroslag welding can be successfully used.

Abstract

1. Direct Cladding of Copper onto Steel using Oscillating MIG Technique (S. V. Dilipan, -M.S. Thesis-1979).

There has been increasing use of copper and its alloys for cladding components which have to handle fluids that need non-toxic and noncorrosive atmospheres. Also it has been found that they perform better under reducing conditions unlike stainless steel, aluminium and titanium which are better in oxidising conditions.
