Impact of variable parameters in K-TIG horizontal position welding on penetration state and its recognition based on OCR-SVM model

Hanjie xuebao
Keyhole tungsten inert gas welding (K-TIG) offers the advantage of single-sided welding with double-sided formation without the need for groove preparation, making it an ideal choice for automated welding processes.

Fabrication of Compositionally Graded NiTi Shape Memory Alloy Laminated Composites Through Hot Roll Bonding and its Characterization

Advanced Engineering Materials, Volume 27, Issue 10, May 2025.
A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Critical Factors Governing the Frictional Coefficient in Mg Alloys—Learn From Machine Learning

Engineering Reports, Volume 7, Issue 5, May 2025.
Machine learning models were successfully used to predict the friction coefficient of Mg alloys based on composition, processing, mechanical properties, and tribological parameters. Normal load, elastic modulus, and Zn content are the most important factors in governing the friction coefficient in Mg alloys. ABSTRACT Data‐driven methods are emerging as

Characterization of the Plasma Shape of the TIG Welding Arc

, 2006
Tungsten electrodes were prepared to analyse the plasma geometry at TIG welding. The investigated electrodes were La02, Th02 alloyed. Tip flatted electrodes were grinded as well. The shape of plasma were analysed for 36 different electrodes.

Solidification of Tungsten Inert Gas–Welded Austenitic Stainless Steel with 0.17 wt% N

steel research international, Volume 96, Issue 5, May 2025.
The classical Scheil model with fast diffusion of nitrogen is used to describe the solidification of the weld seam from austenitic CrMnNi–N steel. The microsegregation of the elements Ni, Cr, Mn, Mo, and N is calculated and compared with experimental findings. Further, the correlation between secondary dendrite arm spacing and cooling rate is made.
