Arc welding

first melt (primary) electrode or stick is made by welding the briquettes together in an inert atmosphere. In the VAR furnace, the electrodes are double or triple melted to produce sound ingot. Like few tens to a few hundreds of briquettes – depending on the ingot size. The VAR process ingot production flow is shown in this flow chart. The primary electrode of titanium is connected to the cathode of the furnace. It is melted by the direct current arc produced between the water cooled copper…

labor force. Most people referred Saint Domingue as sugar island. During the month of August, the French slaughtered slavers set torches to sugar houses and came fields. Thousands of people marched on Cap-Francais. After the march the revolt spreader arcs the colony. At the end of the year, thousands of people were dead including the white people. When the French set the sugar cane fields on fire, the smoke from the fire found its way to the Atlantic trade winds. People were feared for their…

During the welding process, heating may be continued, but frequently the heat from welding is sufficient to maintain the desired temperature without a continuation of the external source of heat. The interpass temperature, defined as the base metal temperature at the time when welding is to be performed between the first and last welding passes, cannot be permitted to fall below the preheat temperature. 2.2.1 Requirement…

Even though helium (He) is the second most abundant element in the universe, it is the most important element. First, let me provide you with some information about helium and its history Helium was first discovered in the sun and not the earth. In 1868, astronomer Pierre Janssen found this gas while watching the colors when the sun was going thru a full solar eclipse. Since the Greek word for sun is helios, he named the gas helium. It was not until 1895 that helium was discovered on earth…

Introduction Definition First we must look at what a robot is and from a definition given by a leading United States robotics research institute, where they defined a robot as a multifunctional, reprogrammable manipulator that has been made and is designed to actuate the movement of tools, materials, specialized devices and parts through variable motions that are programmed in order for the performance of different tasks as required by man (Robot Institute of America, 1979). The term robot was…

CHAPTER 1 INTRODUCTION 1.1 Background To overcome the problems interconnected with manual involvement in production operations, it is essential to step towards automation. One such sector where manufacturer is focusing is on programmable robots. Robot is an electromechanical device which is used to do the specified work prescribed by the human beings. First robot was invented by George devol in 1954. Robots are controlled with the help of computers; the desired work is programmed with the…

Lincoln Electric has become the world largest manufacturer and leading company in the industry of welding equipments. The company was able to maintain a reduced cost and reduced price strategy because of the company’s technological innovation and product and application support, the company was able to earn a price premium for many of its products. In…

For the past two decades, more research efforts have been focused on the development of Advanced High Strength Steels (AHSS). The AHSS include Dual Phase (DP) steels, [1–10], High Strength Low Alloy steels (HSLA), Transformation Induced Plasticity (TRIP) steels, Twinning Induced Plasticity (TWIP) steels, and medium manganese steels, (Bouaziz et al., 2013). The majority of the research are focused on the development of third generation of steels due to interest in the mechanical properties of…

The case study that we were required to read was very interesting as it dates back to the early 1900’s. This means we were able to see the culture of the company and how it progressed over a century of time! I’d like, for a second, to take the abstract thought of how this company held on to its beliefs and values even through all the changes and advancements we’ve have in our culture with people’s rights and the change of the cultural norm. Analyzing the case study you are quickly led to…
