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.
Tensile and Compressive Force: T ensil e Forces A force, that pulls the body, is called as tensile force. Here member AB is tension member carrying tensile force P. As
Evaluate the resultant both in magnitude and direction of the four force acting on the body as shown in figure given below :
how do you differentiate between wet steam and dry steam?
Q. A beam made of C.I. having section of 50mm external diameter and 25 mm internal diameter is supported at 2 points 4 m apart. The beam carries concentrated load of 100N at the ce
Determine the stress in the meridional direction: A doubly curved shell of thickness 8 mm is filled through a liquid under an internal pressure of 2.0 N/mm 2 . At a specific p

Casting processes Casting processes. Here, the metal in the molten state is poured into a mould and allowed to solidify into a shape. The mould may be expendable or permanent.
Reduced costs result from failure Easier fermenter planning (particularly in light of above) Easier downstream scheduling Off the shelf supplies e.g. motors Routine sup
State the assumptions in pin joined trusses?
Determine ratio between mass flow rate to condensing steam: In steam power plant, the steam 0.1 bar and 0.95 dry enters condenser and leaves as saturated liquid at 0.1 bar an
