different tool pin profiles. The formability of welded blanks was evaluated at constant FSW process parameters. It has been found that the welded blanks with square pin profile tool produced better formability properties as compared to other tool pin profiles. It was found that the pulsating action of the square pin profile is said to be the reason for this improvement. A microstructural......
to produce the joints. The results indicate that the weld joints are notably affected by joining with different tool pin profiles. The triangular tool pin profile produces the best metallurgical and mechanical weld properties compared with other tool pin profiles. Besides, the lowest tensile strength and microhardness are obtained for the joint friction stir welded with square tool pin profile......

Combining the geometric relationship and the derivation of the tooth profile equation, the expression of entraining speed... shows the generation principle of cycloid gear tooth profile. The modified cycloid pin wheel transmission has a main working section with θ∈[30°, 120°] [28, 33]. θ is the angle that the arm OOc rotates......
mechanical and electrical performances of the joint. Among the tool parameters, pin profile plays a vital role in determining the material flow path and therefore controls the weld travel speed. The size, shape, and pattern of the stir zone are based on the tool pin profile [5]. Pin profile also plays a significant role in the heat generation. VIJAY and KUMAR [6] revealed that variation in the degree......
