There are lots job aids such like jigs‚ and pipe holders available to help welders do their job and minimize the risk of injury. Special chairs and creepers are available to provide support while performing welding tasks so that bad posture is avoided. There are many causes of injury in the welding field. Common causes of injury are repetitive gripping‚ twisting‚ repetitive reaching‚ and fatigue. Many injuries are developed when there is a mismatch between the capabilities of the worker and the demands

Underwater Archaeology first began in the 19th century when John Deane and Charles Dean excavated the Mary Rose shipwreck (Papadopoulos). It is the scientific study‚ recording and interpretation of the past through the material culture and the remains of human activities that are lying in any aquatic environment. Before the invention of scuba gear‚ excavations predominately took place on land. Due to the vast differences in the environment surrounding excavations on water as compared to on land‚

WELDING Welders are often working on everything you think that has something to do with construction But they work on a lot of things such as; shipbuilding‚ automotive‚ construction and manufacturing industries. Welders work on many dangerous jobs and projects for the whole united states. They work our bridges‚ boats‚ cars‚ roads‚ etc. Welders are basically important without welders there wouldn’t be any boats and bridges that we drive on everyday getting us from point a to b.

What is MIG Welding? Metal Inert Gas (MIG) welding‚ also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas‚ originally argon‚ is also passed through the welding gun at the same

A Definition of Welding Welding is a joining process that produces a local coalescence of materials by heating‚ by applying pressure‚ or both. In essence‚ the welding process fuses the surfaces of two distinct elements to form a single unit. It encompasses a broad range of joining techniques that include fusion welding‚ solid state welding‚ weldbonding‚ diffusion welding‚ brazing‚ and soldering. The Scope and Impact of Welding Welding dates back to the earliest days of metalworking‚ and continues

SBMUnderwater Chaos 1. What’s your reaction to this story? What does it illustrate about decision making? With the vast sums of money invested into large projects like the Eurotunnel (approximately £9.5bn)‚ it amazes observers that important information (i.e. the affect of the cold weather) would not be considered beforehand. However‚ this situation is fairly common in projects that use groundbreaking technologies in extreme environments. These types of projects occur under conditions of uncertainty

I chose the theme underwater because I have found that it provides an optimal learning environment. Children are familiar with under water life from a very early age‚ and I could use that knowledge to incorporate it into my lesson. There’s a vast majority of sea creatures that the kids could fall in love with creating a love for the classroom. Having a bright and colorful classroom will help keep the students alert in class as well as slightly energized. The room will not be too busy that it distracts
