One benefit of using thoriated tungsten electrodes is that they require a much lower temperature for welding than pure tungsten. This means that exposure occurs at a relatively slow rate. Still, exposure must be limited.
It is possible to minimize hazards by using thorium-free tungsten electrodes when possible. The American Welding Society (2003) lists cerium, lanthanum, yttrium, and zirconium as possible alternatives to the radioactive thorium. A second line of defense listed by the American Welding Society (2003) is the installation of an effective dust collection system as well as an effective ventilation system. Of course, training and intelligent storage of thorium are also crucial workplace safety measures. Dust generated by grinding should also be collected and properly disposed of, in accordance with local, state and federal regulations (American Welding Society 2003). When adequate precautions and controls are taken, the ill effects of thoriated tungsten electrodes are likely to be…...

When he was rehired in September, he received a month of training and again failed to pass the test standardized by the American Society of Mechanical Engineers Code, for at-LH welding again. When he was laid off after four months, along with five other welders, he had never passed the test Bechtel had designed for high level welders to qualify for the at-LH welding level.
It appears that Bechtel corporation was conscientiously trying to train Ligon to maintain and upgrade his welding competence, as he was trained for four more weeks than other employees (five weeks in all), and was allowed to take the test twice.
Bechtel did not deliberately discriminate against him in testing, as the test was standardized and every welder in the company, African-American or white, had to pass it. The test was designed according to objective criteria that tested welders on various types of welding work in…...

Compare and contrast the confined space recommendations made by the American Welding Society with those found in Chapter 13 of the textbook.
Chapter thirteen explains confined spaces, as open - topped areas of more than 4 feet in depth. The American Welding Society (AWS) defines this as small rooms, pits, vats, sewers and many other enclosed compartments. The differences between them, is chapter thirteen defines these areas specifically, based upon certain dimensions in contracts with the AWS. ("AWS Safety & Health Fact Sheets," 2013) (Suruda & Pettit, 1994)
Using other web resources, compare and contrast the AWS recommendations for controlling exposure to chromium and nickel welding fumes with those of other organizations. If you were the safety professional reviewing the hazards for manual welding involving exposure to these substances, what controls would you establish?
The AWS recommends not breathing gases and staying away from clouds of toxic fumes. They also state…...

Pipeline welding is a highly specialized field within the welding industry, pivotal for the construction and maintenance of infrastructure that transports oil, gas, water, and other substances across vast distances. The process of pipeline welding demands precision and skilled execution to ensure the structural integrity and safety of the pipelines, which are often subject to high pressure and corrosive substances (Nippes & Smith, 2001).
Welding pipelines typically involves the joining of metal pipes end-to-end by melting and fusing them together. Due to the critical nature of these pipelines, a variety of stringent standards and specifications have been established by organizations such as the American Petroleum Institute (API) and the American Welding Society (AWS). These standards ensure that the welding procedures meet the necessary safety and quality requirements (API, 2012).
One of the most common methods of pipeline welding is shielded metal arc welding (SMAW), also known as stick welding. This method…...

Local exhaust ventilation for the control of welding fumes in the construction industry -- a literature review" and this was published in the Annals of Occupational Hygiene. This paper notes that welding presents a challenge for industrial hygienists with respect to controlling exposure to fumes. The reason is that arc welders typically move from site to site, and these frequent changes in site make it difficult to set up ventilation systems or utilize other similar controls. Thus, the welders are exposed to fumes, because the nature of their work creates such fumes, in these environments where it is impractical to install ventilation systems. Some of the worst industries for this type of exposure are the construction and shipbuilding industries.
The authors looked at the literature on this subject. In particular, they were interested in finding out if LEVs have proven to be a solution. Portable LEV systems are the most…...

Confined Space, Electrodes, Chromium
Confined spaces
A confined space is an enclosed or partially enclosed space that is not primarily designed or intended for human occupancy, it has a restricted entrance or exit by way and size, fined spaces as well poor ventilation. Confined spaces can be below or above ground, it can be found in almost any workplace. A confined space, despite its name, is not necessarily small. Examples of confined spaces include silos, vats, hoppers and utility vaults.
The AS defined confined spaces as having limited space and modes of ingress and egress as well as poor ventilation (American elding Society, 2003a). hile the NIOSH defined confined spaces as sufficient space enough for a person to enter and conduct work, limited means of entry and exit, and does not suit continuous employment. The AS definition is more restricted than that of the broader (Hammer & Price, 2001).

The economic realities of globalization goes beyond just the affects of direct competition for Lincoln. Globalization has significantly affected Lincoln's customers as well increasing their need to continuously improve competitiveness. For this reason, even small improvements on cost efficiency or quality can equate to big profits for customers. In fact, Lincoln's mission is centered on providing the most innovative, cost-effective, quality welding and cutting solutions to their company ("Corporate").Lincoln has capitalized on this with producing one of the few technologically differentiated products in the marketplace.
Another important social trend affecting the company is unionization. In it's long history, Lincoln has never felt the effects of unionization. Much of this is due to management's continued belief from early on that management and employees were an intrinsically intertwined team. Currently, the average employee earns nearly twice as much as other Cleveland area factory workers. However, despite this significant difference in payroll costs, the…...

Although the precise mechanics involved remain unclear, it is likely that during this phase, the high defect boundaries serve as attractors for any imperfections that already existed in the crystal lattice and that the nanocrystals which are, by contrast, relatively defect -- free, become increasingly refined and near crystalline perfection.
3. The final step in the process involves random reorientations of the single-crystalline grains with regards to their neighboring grains. At the point where the grain structure achieves its limiting size (this size limit relates to the particles' crystal symmetry and the energy and amount of mechanical milling employed), the material become amenable to plastic deformation through grain boundary sliding. In fact, this type of deformation mechanism has been discerned in superplasticity in which a high diffusion rate stage is capable of accommodating such forces at any strain rate. esearchers have posited that in the case of the nanocrystalline, the…...

PPE (personal protective equipment) on the job.
esearch shows that Personal protective equipment (PPE) actually denotes to protective clothing, helmets, goggles, or other clothes or gear intended to protect the wearer's body from damage. The dangers that are addressed by protective equipment have to do with the following: physical, electrical, heat, chemicals, biohazards, and airborne particulate matter (Sakaguchi, 2010). Protective equipment is normally worn for job connected occupational health and safety purposes, in addition to for sports and other recreational actions. "Protective clothing" is useful to traditional groups of clothing, and "protective gear" has something to do with for instance guards, shields, pads, or masks, and others. With that said, this paper will discuss the how important it is to have the PPE protection

Pieces must first be cut down to the sizes and specifications listed on the plans you have selected, and shaped into the various different parts for both the siding and the interior of the submarine. This shaping and cutting can require some heavy-duty laser and cutting-edge equipment -- again, keep those friends close, unless you happen to have enough funds to acquire several dozen different pieces of heavy machinery. The heavy equipment needs continue with the next step, which is joining the individual pieces called for in the design through heavy-duty welding, utilizing electric arcs. A watertight craft able to withstand the pressures of deep-sea dives is of course essential to your happiness in your new sub, so make sure those welds are complete.
Once the craft is built, you will need some fissionable material -- enriched uranium is most typically used -- to power the vessel (and, if you're…...
