electrode must be supplied constant current throughout the welding process is carried out. For a continuous supply of electrodes‚ the electrodes are made in the form of wire to be extended out from the nozzle welder automatically at a specified speed. Protective gas is supplied through the nozzle weld as is done in TIG welding. This process can be done automatically or fully automatically. However‚ the MIG equipment more complicated because the process requires continuous huluran uniform electrode

all over the world in laboratories everywhere. The Bunsen burner safely burns a continuous stream of flammable gas. The hose barb is connected to a gas nozzle on the laboratory bench with rubber tubing. Most laboratory benches are equipped with multiple gas nozzles connected to a central gas source‚ as well as a vacuum‚ nitrogen‚ and steam nozzles. Bunsen burner flames depend on air flow in the throat holes. 1. Air hole closed. 2. Air hole slightly open. 3. Air hole half open. 5. Almost fully open

Steam Turbines: A look into how a steam turbine functionsStacy L. Rousseau EE ’03 At a time when energy is such an issue in our country‚ it may be surprising to realize that the major technology involved in producing electrical energy today was developed over a century ago by Charles G. Curtis: the steam turbine. The aim of a steam turbine is to produce the maximum amount of electrical energy in the minimum amount of space. Today‚ steam turbines produce more electrical energy than any other system

of actual running time and repairs had been made twice a month for the last six months. Keeping the machinery in top-running condition has not been a priority and its’ effects have been felt down the line with over-pressurized cans. The plastic nozzle heads were often found with burrs on the inside rim. This forced the company to increase the application pressure at the filling head to solve this problem. Quality is being affected within the “materials” variable. Finally‚ there are numerous

Question: Do you think the ballistic missile defence program is a good idea???? Answer: Answering this question the first thing which come into our mind is that “Ballistic missile” what is ballistic missile….? Definition of Ballistic missile:- “Ballistic missile is a missile with a high‚ arching trajectory‚ which is initially powered and guided but falls under gravity on to its target which set on the time of fire.” What is Ballistic missile:- A missile that is follows a ballistic trajectory

and prevents this gas from escaping. When you pull the safety pin and squeeze the lever‚ the lever pushes on an actuating rod which presses the valve down to open a passage to the nozzle. The compressed gas is released‚ applying a downward pressure on the fire-extinguishing material. This pushes the material out the nozzle with high amounts of pressure.” ("Fire

(LCS) Low-carbon steels contain up to 0.30% C. The largest category of this class of steel is flat-rolled products (sheet or strip)‚ usually in the cold-rolled and annealed condition. The carbon content for these high-formability steels is very low‚ less than 0.10% C‚ with up to 0.4% Mn. Typical uses are in automobile body panels‚ tin plate‚ and wire products.
