Influence of Forming Graphite Skids on the Change in Hardness of Deposited Multilayer Specimens

Abstract:

The paper investigates the influence of the forming graphite skids on the change in the hardness of multilayer samples made of stainless steel AISI 308LSi deposited by electric arc welding in argon. Utilization of graphite skids makes it possible to obtain a product with a smoother outer side surface. An increase in the fraction of the austenite phase is observed in the samples obtained using graphite skids. An increase in the proportion of the austenite phase leads to an overall increase in the hardness of the product.
