PROS AND CONS OF UNDERWATER WELDING To briefly present the advantages and disadvantages of underwater welding let us first separate this two compound words‚ the UNDERWATER and WELDING. Underwater is anywhere where this is water‚ either in low or in deep aquatic areas. Now‚ Welding is the action of burning something (particularly a metal) into creating or fixing something with the use of a high temperature to burn down or melt a metallic material so that it can be reformed. Combining this two concepts

Welding of Joint : * Clean the joint surface. * Preheat the joint area of shell ( 1m lg ) to 150 deg * Welding electrodes are to be preheated * Complete the root run on the outer surface of the joint side with 2.5mm electrode. * Next with 4mm electrode & then 5mm & 6 mm electrodes. * Gouge & remove the root run weld from the inner surface of the joint‚ check with Dye penetrant for any cracks and start the root run inside. * Complete the inside welding.

Arc Welding (SMAW) is the most widely used welding process in the small scale industries‚ because of its low cost‚ flexibility‚ portability and versatility. Shielded metal arc welding is one type of welding process which uses consumable electrode consist of filler core rod coated with chemicals that will help during welding by providing flux and shielding. This process give pure and clean weldment that has high material deposition rate compared to traditional welding process. The SMAW welding parameters

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
