The projected salary and the job demand in the next 5 to 10 years. It tells about how welding is very important to our economy. Also my research tells what certifications and licenses I will need to get and the jobs I can do just by learning to weld. My research paper is on the trade welding. Welding

played with lasers? We have all loved the laser fights in movies like Star Wars. Who wouldn’t want wield a laser around while fighting an enemy. Did you know that the term laser came from an acronym meaning “light amplification by stimulated emission of radiation.”? It should actually be all capitalized but for simplicity it isn’t. The first working laser was actually demonstrated by Theodore Maiman at the Hughes Research Laboratories back in 1960. The strength of early lasers was measured

What is laser retinal detachment surgery? How does the lasers work? What is retinal detachment? In the early 1970’s‚ laser were first used to treat eye diseases and has since then become the standard practise for formerly untreatable disorders. Even when there is haemorrhaging and leakage in the back of your eye‚ almost always‚ the eye will look and feel normal when suffering from retinal diseases. Therefore‚ the only way to conclude the necessity of laser surgery is to have a careful‚ dilated retinal

Fusion welding and non-fusion welding Fusion welding is defined as a welding process of using heat by melting the base of metals in order to joint similar types of metals together. Filler is used in this welding process to provide bulk and strength to the welded joint [1]. Whereas non-fusion welding which is known also as solid state welding is a welding process where a particular amount of heat is applied to the joining metals which essentially below the melting point of the base metals that being

For the assessment of risk In order to work safely in a welding environment‚ it is necessary to be able to identify hazards and assess risks. To do that‚ one needs information‚ education‚ training and experience in the appropriate field of work. Legislation Employers have a duty to provide information‚ instruction‚ training and supervision to ensure health and safety at work. Employees have a duty to take care of their own health and safety and those of others‚ and must not intentionally or recklessly

Laser eye surgery has enabled millions of people to throw away their eyeglasses. Now several medical technology companies are hoping that lasers aimed at the feet will allow millions to take their socks off‚ even in public. The target is toenail fungus — an infection in an estimated 10 percent of American adults‚ or 23 million people — that causes toenails to become thick‚ yellow and fetid. If these lasers‚ which recently completed small clinical trials‚ work‚ they will represent a new way

name of our project is ‘Balancing Beam’. My teammate and I decided to build balancing beam is because when we discuss with the children‚ they wanted to build something which is fun and challenging project. After we collected the information from the children‚ we started to discuss with our principle and the principle gave us some advice. Then‚ we decided to build a balancing beam. When we were having a small meeting with the children to discuss about the balancing beam‚ the children feel excited and

BENKELMAN BEAM METHOD A.C.Benkelman devised the simple deflection beam in 1953 for measurement of pavement surface deflection. It is widely used all over the world evaluation of the requirements of strengthening of flexible pavements. This method is done to lay down a uniform procedure for the design of flexible overlays or per I R C:81-1981 here a tentative guideline was published by the Indian road congress under the title “Tentative Guidelines for strengthening of flexible road pavements using
