What is semiautomatic welding? Semi-automatic welding is manual welding with equipment that automatically controls one or more of the welding conditions. The welder manipulates the welding gun to create the weld while the electrode is automatically fed to the arc. What two welding processes are semiautomatic processes? What two welding processes are semiautomatic processes? By […]

What is the accuracy of a tape measure?
What is the accuracy of a tape measure? Up to 12 ft., a precision tape measure will be accurate to about ±1⁄32 in.; beyond 12 ft., it’s within ±1⁄16 in. Other areas for potential error include the hook at the end, which, if not precisely assembled, can cause inaccurate measurements. Which measuring tool was more […]

What is the difference between Q and K in equilibrium?
What is the difference between Q and K in equilibrium? Re: Difference between Q and K. The difference between K and Q is that, K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage of a reaction. Therefore, […]
