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

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

Hot tap operation is a combination of many variables‚ welding is only one of them‚though it’s critical for any hot tapping operation. Note Hot Tap could lead to serious fatalities if not done properly. Since you mentioned about Shell’s DEP‚ please note these DEP’s are well respected in the industry. That does not mean what’s written is absolutely unquestionable‚ but there’re good rationale on what’s written in the DEP’s.
