Transient thermal responses on 316L stainless: Part one

14 May 2019

In their article, ‘Investigation on transient thermal responses on 316L austenitic stainless steel and low carbon ferritic steel welding using pulsed Nd: YAG laser (Part one of two)’, Kuman KS from the University of Madras, talks about the welding of different combinations of materials’ joints in accordance with change in working/operating temperature, and how it is seeing a rise in demand throughout the industry, due to both technical and economic reasons. 

“However, many problems incurred with dissimilar joints such as selection of filler metal, different thermophysical, and mechanical properties; therefore, the selection of proper welding variable is very important,” Kuman explains. “In most of the power plants, dissimilar welds joints are employed in many circumstances, one of those is to connect the heat exchanger to external pipe systems at the tailor ends. The combination of 316L austenitic stainless steel and low carbon ferritic steel is often used for these circumstances since it possesses a good combination of mechanical properties, formability, and weldability.”
