. Safety aspect of glow sticks Glow sticks are a form of lighting typically used in events and parties. The chemicals responsible for luminescence are contained within a plastic case. The chemicals are separated by a glass vial‚ such that when the stick is bent‚ the vial breaks and allows the reaction to occur. In general‚ glow sticks are considered safe to use. None of the chemicals used are classified as radiation‚ flammable or explosive hazards. Some of the chemicals however‚ are classified

Underwater welding‚ Underwater welding was invented in Russia in 1932 by Konstantin Konstanovich Khrenov and used it throughout the soviet navy. During WWII‚ the American Cyril D. Jensen‚ professor of engineering at Lehigh university‚ developed the USA’s own underwater welding programs and created 2 U.S. patents in the field. (Agnew‚ 1999-2013) Under water is a technique that is employed in various engineering projects‚ where in welding is carried out under the surface of the water. Underwater

[2] reported that the use of pulsed arc welding in place of conventional GTAW increases the output by 200–400%‚ reduces consumption of argon by three to ten times‚ and also reduces the cost of 1 m weld deposition by three to five times. The aim of pulsing is mainly to achieve maximum penetration

resistance spot welding process parameters on the shear-tensile strength of the welded joints of Inconel alloy 625 was investigated. Experimental study using full factorial design of the welding current‚ welding time‚ and electrode force parameters was conducted. In order to identify the influence of each parameter and their interaction a general linear model and a second order model using response surface method was developed. Nonlinear correlation was observed between the welding process parameters

junior year of high school started‚ things took a major change. The year before‚ I signed up for dual-credit welding‚ mainly because it sounded like an easy class to get dual credits from. On top of that‚ I have always felt comfortable around workshop environments‚ so it was a win-win situation for me. The first few weeks of welding

How to String a Lacrosse Stick Good afternoon ladies and gentlemen‚ my name is Garrett Barker‚ and today I’d like to talk on a subject that interests me a lot; lacrosse. More specifically‚ I’d like to teach you guys something I’ve picked up over the years. Some of you might be like Sammy or Paul and automatically dismiss the idea of lacrosse based on a previous bias they have made from baseball. But according to multiple sources such as Sports Illustrated and Business Insider‚ lacrosse is by

NO THANKSGET THE APP how heat affects metal when it is being welded (peasecha) Charles Pease 3-29-16 English 10 How heat produced from welding affects metal The heat produced from the welding process can cause deformation and can also cause changes in the metal at a molecular level. This can make the metal brittle and even deform it. When the arc is struck and the metal starts to become molten it reaches temperatures in an excess of 8‚000 degrees fahrenheit and such a large input of heat

set in stone for me to see the welding lab. After meeting and learning about all the different opportunities there are after attending this school‚ we finally got to meet with Mr. Jezylo and Mr. Paulsen. As soon as I entered the shop I instantly felt at home. The humming of the welding machines‚ the loud crash of metal falling to the floor after being cut‚ and the sparks flying as students are welding were amazing. I could’ve spent forever in there learning about welding and what it takes to become
