1. Introduction Oxy Acetylene welding is one of many kinds of welding. The fundamental process is to joint two parts of metal becoming one part by a high temperature. The thermal flame is created by using the mixing of oxygen and acetylene gas (anthonycastronovo, nd) 2. Compatible materials are used for oxy acetylene welding: - Mild steel Aluminum, stainless steel, copper and brass. However these things are suitable for brazing process (anthonycastronovo, nd) 3. Before the welding procedure…

The primary focus of the lab was to understand the process and effects of cold working and annealing compared to a baseline sample. Cold working is a form of strain hardening in which metals are worked through the use of applied pressure, thereby making the metal harder[]. This applied pressure led to harder material by creating linear defects known as dislocations. The specific type of dislocation that occurred in this lab was an edge dislocation where an extra plane of atoms was inserted into…

once, for example sand mould casting, the lost-wax method and precision casting. For larger quantities of liquid metal, there are basically two methods: ingot casting and continuous casting. Ingot casting normally uses a permanent mould made by cast iron isolated by ceramic material. There are limitations with the ingot casting methods. The structure in the centre of the ingot will get coarse which decreases the strength of the metal and when casting larger quantities of metal the handling of…

S elements in a representative single nanoparticle of the PtFeS catalyst as shown in Fig. 3c. Overlapping the mapping of Pt, Fe, and S EEL signals from a single nanoparticle validates the core–shell structure, indicating the formation of sulfur and iron atom-rich core and Pt-rich shell. Those structures could form more favorable compressive strain on Pt because of the contraction by binary alloy of Fe and S in the core. The apparent positive effect of PtFeS core–shell structure enables…

Have you ever been bewildered about what life was like on a Texas plantation? After reading this you will hopefully have solved some of those absurd mysteries. What was life truly like as a slave? How did the ancients endure? How do you get tools when you can’t go to the store? Well, if you needed any weapons in the past, you would generally go to the blacksmith. Blacksmithing is a fascinating job that keeps the culture of medieval castles and knights alive. Understanding blacksmithing is a…

fat I should switch to nonfat chocolate milk and skip the fried chicken and have grilled chicken on my sandwich; additionally, I should delete the bacon on my omelet. On this particular day, my mineral intake was under for dietary fiber, potassium, iron, and magnesium. I could gain soluble fiber by adding oatmeal, kidney beans, apples, pears, and carrots to my diet; consequently,…

This project is over a career that i would want in the future. In this paper i will be writing about welding. First i will tell you what welding is. Welding is the act of fusing metal together by basically melting the metal together. Welders can be found anywhere in the world. If there is something to be built with metal you’ll find a welder there. There are several different duties of being a welder. You must be able to read blueprints, be able to read a tape measure, maintain equipment such…

Curt Phillips MEC 113 Project Screwdriver A screwdriver is a hand tool which is considered to be used as a hand-operator to unloose a screw with slotted heads. The first characteristics for screwdriver that it is a shaped like a cross, and has a beveled tip. The second characteristic for screwdriver that it has a tip of a flat-blade tip. It is flat and tapered, and somewhat like a chisel. The materials that are made for the handle of a screwdriver are steel, wood, metal or plastic. In…

How many parts does the basic lacrosse stick have? It is composed of three parts; a loosely woven or net pocket, aluminum or hardwood handle or shaft and a strong plastic head. The different parts of the stick can be changed out or replaced to give the player flexibility and a greater feel for performance during the game. Depending on the position of the player different sticks apply to different positions. The size, shape and length will very according to the need and requirement for any given…

Throughout this exhibition, I have created one specific theme—to take you through the technique of gilding and the material of gilt bronze. Gilding or Ormolu is a “decorative technique for applying fine gold leaf or powder to a solid surface such as wood, stone, or metal to give a thin coating of gold.” In this case, the exhibition will revolve around gilt bronze Asian artwork. Let us take a tour through multiple pieces and learn about the gilding technique, and how the material has held up…
