Phases, structures, and the influences of temperatureWhen you heat or cool a piece of metal to a specific temperature, that metal goes through what's called a phase change, in which its crystal structure changes. Sometimes the change is obvious. For example, when a piece of metal melts, it goes through a phase change when the crystal structure breaks down and the metal goes from solid to liquid. When it solidifies it's also a phase change, as the structure re-forms from liquid to solid.

Workplace stress—Part 1Stress is a fact of life. It's here to stay, and even if we could abolish it, we wouldn't want to. At its best, stress can be the catalyst that moves us to make changes and achieve great things in life. At its worst, it can create all kinds of emotional and physical problems. What determines whether stress is a friend or foe? Whether it precipitates changes that improve our lives or whether it greatly diminishes the quality of our lives? One determining factor is how we handle or manage stress. We can be our own best friend or our own worst enemy.

Selecting the best lens for welders' eye protectionIn the industrial environment, safety glasses are a necessity for jobs that put employees' eyes at risk of exposure to heat, impact, chemicals, or dust. But workers also need protection from nonimpact dangers, such as radiant energy, eye strain, and fatigue. So choosing the appropriate lens or filter plate for your workers' eye protection is just as important in preventing eye injury as is selecting the appropriate style of safety eyewear.

Material handling safetyHandling material is a daily function in the workplace. All too often it is a task taken for granted, with little knowledge of or attention to the consequences if done incorrectly. Management and employees need to look at and evaluate how material goods are handled inside and outside their facilities. Whether the operation involves delivering or receiving material, an area should be designated for that purpose.

Occupational injury and illness statistics: Where does your manufacturing job rank?In December 2003 the U.S. Department of Labor's Bureau of Labor Statistics (BLS) released its 2002 occupational injuries and illnesses data. A total of 4.7 million nonfatal injuries and illnesses were reported in private-industry workplaces during 2002, resulting in a rate of 5.3 cases per 100 equivalent full-time workers. Among goods-producing categories, incidence rates ranged from 4.0 cases per 100 workers in mining to 7.2 cases per 100 workers in manufacturing. These numbers are overall averages of subsets in each major category.

Pairing a servo feed with a pull-through straightener: Applications for noncosmetic stamped partsThis article explores the possibility that servo feeds can be used with pull-through straighteners as opposed to a conventional feed line that uses a powered straightener. Using the servo-PTS (pull-through straightener) can save money on equipment and material. The only limitation may be marking the material so noncosmetic applications are recommended.
|
 |
Getting it Straight: Understanding coil straightening in stamping operationsBefore coiled material can pass through a die to produce an acceptable part, it must be straightened. Coil straightening is accomplished by bending a strip of material around sets of rollers that alternately stretch and compress the upper and lower surfaces so that the material's yield point is exceeded.

Minimizing wall thickness variation in seamless tubingAll mechanical steel tubing has some amount of wall thickness variation. Wall variation in welded tubing results from the strip manufacturing and tube welding processes. Seamless tube, which is created from a hot billet of solid steel, has wall variation that results from tooling wear, bearing and shaft variation, and normal hot-process variation. The wall thickness in seamless tubing varies in the cross section and along the tube's length.

Al GMAW: CC or CV?For about 40 years, a great debate in welding is whether to use constant-current or constant-voltage power supplies when using gas metal arc welding on aluminum. Constant-current power supplies made sense 30 years ago and are still used in some applications today, but for most applications, constant-voltage power supplies are suitable for gas metal arc welding aluminum.

Choosing the right oxyfuel gas and supply systemMixing oxygen with fuel gases for brazing, cutting, heating, and welding metal has been around since the early 1900s. Oxyfuel processes have remained in use over the years despite the introduction of other metal fabrication processes, such as arc welding, plasma cutting, and laser materials processing. Finding the most economical method for supplying oxyfuel gases requires a basic understanding of the process.
