n architecture‚ a truss is a structure comprising one or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes. External forces and reactions to those forces are considered to act only at the nodes and result in forces in the members which are either tensile or compressive forces. Moments (torques) are explicitly excluded because‚ and only because‚ all the joints in a truss are treated as revolutes. A planar truss is one where all the members

Fix the rack is carried out with manganese steel surfacing surfacing . Before welding ‚ welding rod to dry ‚ after welding‚ the surface should be smooth ‚ symmetrical position rack surfacing weight should be balanced ‚ otherwise it will affect the hammer work. This method is simple‚ the cost is higher‚ but the wear resistance can be increased more than 1 times .

metal together and it is really fun. You also get to weld metal on to all different kinds of cars. The career I am doing is welder. In welding you weld metal together and you weld metal onto cars. Welder means a person who welds‚ especially as a profession. I chose this career because I really like to weld metal together and I always wanted to open my own welding shop. Another reason is I thought it would be fun to be a welder‚ because you would see sparks flying all the time. I would like to

AHSS after exposure to elevated temperatures during repair welding or flame straightening and could seriously affect the structural performance of AHSS components after repair. This study‚ requested by General Motors ’ Collision Repair Tech. Center‚ examined the mechanical behavior of two AHSS products‚ a 600 MPa tensile strength (TS) dual phase steel and a 1300 MPa TS Martensitic steel‚ after exposure to typical repair arc welding and flame straightening temperature cycles and developed recommended

should weld Don’t be afraid of the future‚ Build it. Welding is a neat and fun activity that you can build cool things from. Welding is not hard and you can learn to do it. You can do this on your free time. From welding projects and other things you can make money from them by selling them. If you have never welded in your life before you can still learn to weld. It’s not hard to learn and you can do some cool things. All you need is a welding helmet‚ welder‚ and the cables. It may take a little

GAS WELDING Gas welding is a process that use fuel gases and oxygen to weld and cut metals. Uses: 1-welding and cutting metals 2-in Stone Work for flaming 3-in the glass industry for fire polishing 4-in jewelry production How we use it : The apparatus used in gas welding consists basically of an oxygen source and a fuel gas source it’s pumped through hoses and get out to cut or weld the used metal and there are two cylinders one of them contain oxygen and we can control
