4.7 Fiction Stir Welding Cost Model
This suggestion model considers various cost components engaged in the total cost valuation of a friction stir welded joint pipes. Friction stir welding cost suggestion model is structured using the major cost components. The representative components of a friction stir welding pipes cost evaluation are listed below [37-42]:
1. Labor cost (weld preparation time + actual weld time)
2. Power cost
3. Machine cost
4. Tooling cost
The sum of all the component costs discussed above results in the total cost of the joint and can be expressed mathematically as follows [69-72]:
C_Total=C_L+C_M+C_P+C_T
4.7 .1 Labor cost:
This is one of the most expensive elements contributing to the total weld cost. It should be accounted for properly because careful attention …show more content…
This shows that the cost of the joint for these thicknesses varies with the rotation speed and travel speed of the weld and with the thickness of pipes.
It concludes that the total cost of weld joint was less at lower rotation speeds (485 RPM). As the rotation speed is increased from (1800 RPM), there was a significant increase in the total cost also.
Fig (4-85) to Fig (4-87) show the relation between rotation speed and total cost distribution with respect to the rotation speed and travel speed of weld and material thickness 2 mm thickness of the pipe friction stir
