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

Cardiovascular Case Study Atrial Septal Defect(ASD) is a very large problem concerning the heart in its overall function. When the heart‚ being the core of the cardiovascular system‚ has issues; it effects the rest of the body as a result. The core of the problem resides in the atrial septum. Normally the heart is divided into four separate chambers. But a person with atrial septal defect has an atrial septum that allows the blood from the left side of the heart back into the right side.

born with Ventricular septal defect‚ VSD is a common complication in new born presented at child birth. Also a small percentage of adults can get Ventricular septal defect after a heart attack or surgery. VSD is detected mostly right after birth when a child is getting evaluation from a medical doctor. VSD is a treatable defect by surgery or also if the hole in the heart is small they can live with the condition for the rest of their life. (Ventricular Septal Defect: Facts on Inborn Heart Problems

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
