The topic I am researching for my I-Search is welding. The reason I want to be a welder is because it is something I really enjoy doing and many of my family members are welders. Welding has many ups to the job but it also has its downs to it also.The ups to the job are it pays well in the beginning and the more experience you have the more you make and you also get to admire the work you did. The downs to the job are you tear down your body very quickly and also have the chance to have a pipeline

WELDING OF CAST IRON Cast iron is an extremely versatile material‚ used in thousands of industrial products. It is hard‚ wearresistant‚ and relatively inexpensive. Like steel‚ it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility)‚ this is not true of all cast irons‚ as we shall see shortly. Cast iron‚ like steel‚ is an iron-carbon alloy. In composition and structure‚ and in some of its properties‚ it is quite different

Thermo-elasto-plastic analysis will be used to replicate the butt welded pipe joint and the residual stress will be determined. Residual stress that arises in welded joints by heating and cooling cycles during the welding process is another major factor in fatigue failure of welded structures. Welding residual stresses might lead to a drastic reduction in the fatigue strength of welded elements. In multi cycle fatigue (N > 106 cycles)‚ the effect of residual stresses can be comparable to the effect of stress

Is Our Constitution Still Relevant? The United States Constitution is often called “a miracle document” because it has proved so enduring while so many other attempts at self-government have failed. In reality‚ it was a miracle of sorts that the Constitutional Convention ever materialized in the first place. This is one of the reasons I believe the constitution is still relevant. The articles of confederation weren’t working so the constitutional convention was finally held in order to draft the
