...The Art of Welding Welding is defined as the process of joining together metal pieces or parts by heating the surfaces to the point of melting using a blowtorch, electric arc, or other means, and putting them together by pressing or hammering. Welding is more of an art rather than a skill. It takes a special person to be able to completely master the art. Skills that a welder would need to have would be a very detail-orientated mind set. (Welding Basics) anyone can weld, but nobody is going to pay someone to weld something together crappily. The reason I am doing my research on welding is because I want to figure out if this is what I would like to do the rest of my life. I only have minor experience with welding. But, the experience I have had so far has been fun and exciting. Most of the work I have done with welding has involved my cars which is most likely the biggest reason that I have become so interested in this field of study. I have figured out that training for welding workers can range from a few weeks of school or on-the-job training for low-skilled positions, to several years of combined school and on-the-job training for highly skilled jobs. Training is available in high schools, and other types of institutions such as technical institutes, community colleges, and private welding schools. The Armed Forces have welding schools as well. (Jeffus,153) While some employers provide basic training, they prefer to hire workers with experience or more formal training...

...Electroslag Welding Electroslag Welding Electroslag Welding is a welding process, in which the heat is generated by an electric current passing between the consumable electrode (filler metal) and the work piece through a molten slag covering the weld surface. Prior to welding the gap between the two work pieces is filled with a welding flux. Electroslag Welding is initiated by an arc between the electrode and the work piece (or starting plate). Heat, generated by the arc, melts the fluxing powder and forms molten slag. The slag, having low electric conductivity, is maintained in liquid state due to heat produced by the electric current. Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 50 mm) materials in a vertical or close to vertical position. An electric arc is initially struck by wire that is fed into the desired weld location and then flux is added The slag reaches a temperature of about 3500°F (1930°C). This temperature is sufficient for melting the consumable electrode and work piece edges. Metal droplets fall to the weld pool and join the work pieces. Electroslag Welding is used mainly for steels.

...1 Arc welding - an overview 1.I History of welding Methods for joining metals have been known for thousands of years, but for most of this period the only form of welding was forge welding by a blacksmith. A number of totally new welding principles emerged at the end of 19th century; sufficient electrical current could then be generated for resistance welding and arc welding. Arc welding was initially carried out using carbon electrodes, developed by Bemados, and was shortly followed by the use of steel rods. The Swede Oskar Kjellberg made an important advance when he developed and patented the coated electrode. The welding result was amazing and formed the foundation of the ESAB welding company. Figure 1. I Principle of Manual Metal Arc ( M M ) welding. Another early method of welding which was also developed at that time was gas welding. The use of acetylene and oxygen made it possible to produce a comparatively high flame temperature, 3100°C, which is higher than that of other hydrocarbon based gas. The intensity of all these heat sources enables heat to be generated in, or applied to, the workpiece quicker than it is conducted away into the surrounding metal. Consequently it is possible to generate a molten pool, which solidifies to form the unifying bond between the parts being joined. Figure 1.2 Submerged arc welding. © 2003, Woodhead Publishing Ltd WELDING PROCESSES HANDBOOK Later, in the 1930s, new methods were developed. Up until then, all metal-arc welding...

...for even ventilation of both lungs. Flow tests simulating surgical ventilation conditions were conducted. These results confirmed that adequate air flow could be obtained independent of any pressure differences across the membrane. Tests of the prototype also confirmed that maximum instrumentation diameter was increased through this design when compared to a commercially available ETT with identical outer dimensions (35 Fr). Finite element analysis was conducted to determine the necessary thickness of the membrane for a safe design. One key design feature of the membrane is that its state of maximum deflection (2.1mm) does not significantly hinder airflow through the smaller lumen. Tests to further evaluate the functional requirements of safety and ease of use are currently under way. Methods of manufacturing this design are also under investigation. Keywords: endotracheal tube, flexible membrane, airway access, neutral axis INTRODUCTION Endotracheal tubes (ETT) are used to maintain patient airway access during surgical procedures. During thoracic surgery it is often necessary to ventilate the lungs separately. This allows one lung to be ventilated, while the other may be deflated.

...Victoria Gribble Network Administrator & Payroll Clerk S & S Welding, Inc. 22131 68Th Ave South; P.O. Box 1505 Kent, WA 98035-1505 Dear Victoria Gribble: I’m writing in response to your welder fabricator apprenticeship opportunity listed in an S & S advertisement. The opportunity is of interest to me as a means for furthering my career and education in the welding field. My current education include classes in advance welding and metal sculpture all of which all involve TIG, MIG, and Torch, I am skilled in all 3, and I can work well in a team environment or independently. My most recent work experience was as a deep water Lifeguard at a popular theme park. This job demanded that I stay focused and alert because the lives of many depended on the attention me and my co-workers paid to assure that lives were not at risk. I learned that communication was ultimately important when it came to teamwork. Being able to effectively communicate with other team members was a skill beyond what was demanded of me physically to assure that all life safety elements were properly in place. I can see that this skill would also be important for a welding apprenticeship position. As a volunteer I have worked in supervisory capacities with young children. This experience called upon my ability to effectively communicate as well as to problem solve. Assuring that the needs of all children were met often required negotiation and compromise. My intention was to problem...

...operation. B&L manufactured approximately 40 trailers per year, with about two-thirds produced during the period from November to April. The outrigger bracket, part number T-178, was an accessory that could be used to secure oversized containers. The bracket consisted of four component parts welded together, and each trailer sold by B&L had 20 brackets – 10 per side. The Metal Fabricating Division was presently manufacturing the outrigger bracket. The subassembly parts – T-67, T-75, T-69, and T-77 – were processed on a burn table, which cut the raw material to size. Although the burn table could work with eight stations, this machine had only been operating with one station. The final assembly operation, T-70, was performed at a manual welding station. Manufacturing lead time for the outrigger bracket was two weeks. However, the Metal Fabricating Division had been able to coordinate supply and production with assembly operations. Consequently, finished inventory levels of the outrigger bracket were kept to a minimum. B&L’sinventory holding costs were 20 percent...

...WELDING TECHNICIAN I always loved doing activities with my hands, crafting different items out of raw materials. I remember when I took woodshop and welding class at high school and I enjoyed how I had the opportunity to create and sculpt items. That’s why I feel becoming a welding technician would be great for me. Welders are needed all over the world, its like you have endless work . Welders are in high demand they‘re need for everything when it comes to manufacturing. It just sounds like everything i'm looking for in a career. The reason I chose this profession was because I’m a hands on kind of guy. I like to get my hands dirty. Ever since I was a little kid, I was always dismantling things around the house. I stayed in trouble with my mom. As I become older, I started to notice that I was pretty good with my hands. My mom was always asking me to repair things around the house, like the dvd player or the lawn mower or just odd jobs around the house. But what really interested me in the welding job was my welding class. I had a teacher named Mr. Green who taught us the safety procedures, proper clothing to wear and welding using the basic methods. I found the class very interesting, We created tables, chairs, and a barbeque pit and even statues from raw metals. This class really made me want to become welding technician. Based on my personality assessment from type focus, my personality type is “introversion, intuition, thinking and perceiving”. This...

...point in 2006, Stropki looked back on his company’s more than 100 years in the welding equipment and consumables industry with pride, wondering whether a strong push into India should be the next step in his company’s globalization. An India expansion had been considered for several years, but thus far the company had focused on growing its operations in China and elsewhere around the globe. If Stropki were to approve a significant allocation of resources toward an India expansion, he wondered what would be the best way to enter. He had a wealth of company lessons and experiences to apply to the India investment decision, as his company had had international operations since the 1940s, had struggled internationally in the late 1980s and early 1990s, and had gone on to regain its global competitive advantage in the late 1990s and early 2000s. During Stropki’s tenure as CEO since 2004, the company had further expanded globally and by 2006 owned manufacturing operations in 19 countries across five continents. Most recently, the company had enjoyed increasing success in China as a result of its aggressive expansion through both a joint venture and set of majority-owned plants. As Stropki opened the Cleveland newspaper to check the previous Sunday’s Cleveland Browns score, he wondered how he could apply the lessons of the Chinese experience in particular, to India.
