An item of protective gear that shields individuals passing by from stray sparks or metal during the welding process performed by another worker is known as: E. Welding Screens.
An operator is a person tasked with joining two or more metals using a technique called wielding.
In the course of wielding, both sparks and tiny metallic fragments are released, which pose a danger to the operator and others working nearby.
As a result, the equipment outlined below should be worn or utilized directly by a worker actuating the wielding process:
Nonetheless, a type of protective gear that defends other workers nearby from stray sparks or metallic fragments while the operator (worker) is in the act of welding is called welding screens.

Response:
The cutting speed is calculated at 365.71 m/min
Clarification:
Given parameters include
diameter D = 250 mm
length L = 625 mm
Feed f = 0.30 mm/rev
cut depth = 2.5 mm
n = 0.25
C = 700
To find
the cutting speed that ensures the tool life coincides with the cutting time for the three parts
The formula for cutting time is given as
Tc =
....................1
where D refers to diameter, L refers to length and f refers to feed while V represents speed 
Thus, we derive
Tc = 
Tc = 
Given the tool life is expressed as
T = 3 × Tc............................2
where T denotes tool life and Tc is the cutting duration
Calculating tool life by substituting values into equation 2 yields
T = 3 ×
According to the Taylor tool formula, cutting speed is expressed as
× V × 8.37 = 700
This yields V = 365.71
Thus, the cutting speed calculates to 365.71 m/min
