SHIELDING GASES
Shielding gas is directed by the torch to the arc and weld pool to protect the electrode and the molten weld metal from atmospheric contamination.
Argon and helium or mixtures of the two are the most common types of inert gas used for the shielding. Argon hydrogen mixtures are used for special applications.
Determine the deflection at free end: For the beam illustrated in Figure, determine the deflection at free end and the maximum deflection. Figure Solution R

why 4R kinematic chain do not form different mechanisms?
Explain the Laws of Thermodynamics Usually thermodynamics contains four laws; a. Zeroth law: this law deals with thermal equilibrium and establishes an idea of temperature.
Constituents of seam welding The essential elements of a seam welding machine are: Main frame containing welding transformer and tap switch. Welding head consisting o
Cobalt-base super alloys (e.g. UNS R30155 (Grade 661) and R30816 (Grade 671)) have superior strength to the nickel base alloys above 1800°F (980°C). The refractory metal alloys
I am studying in Final Year of Engineering(Mechanical) and I would like some help for the project. It will be helpful if you suggest some project related to Automation.
