Dataset of dimensionless operating conditions for welding and metal additive manufacturing

The present dataset contains the dimensionless operating conditions obtained by processing a wide range of welding and metal Additive Manufacturing (AM) process parameters through a unified theoretical framework based on the Rosenthal solution [1]. The exploratory data analysis covered Arc and Beam Welding (AW and BW, respectively) on various materials, joint types, and bead sizes ranging from 0.5 to over 10 mm. As for AM, we considered Laser Metal Deposition (LMD) and Selective Laser Melting (SLM) on steel, Al, Ni, Ti, Cu, and Co-Cr alloys by limiting the research to the last five years of published literature.

Nomenclature:
U Velocity magnitude
P Power
p Welding power (AW and BW)
d Distance between adjacent scan lines (SLM)
s Nominal layer thickness (SLM)
Τ0 Initial or preheating temperature
R ̅ Melt pool half-width
Ar Melt pool aspect ratio
Ũ Dimensionless velocity
P ̃ Dimensionless power

Welding joint types are identified by the initials B, L, and T, standing for Butt, Lap, and T- joints, respectively.
