	Where abrasive waterjets shine: No-HAZ process makes inroads into HSS, metallic composites, special fabrications By: Dr. Mohamed Hashish, Contributing Writer Abrasive waterjet's cold-cutting and omni-directional capabilities make it especially well-suited to cutting unusual shapes out of exotic and heat-sensitive materials. Also, because abrasive waterjet is a cold-cutting process, it does not create a heat-affected zone (HAZ), which can make it more difficult to execute downstream processes, such as welding.

	Mill coolant system design: Lubrication is more than meets the eye By: James Dyla, Contributing Writer What kind of coolant system you construct for your tube mill or roll forming operation is just as important as what type of coolant you use. Publish date: May 15, 2001 Tech cell: Roll Forming
	Keep it clean: Selecting the right waste treatment option By: John Burke, Contributing Writer Are you having problems with wastewater discharges from your metalworking facility? Have you received a violation notice from your sewer use authority? Do your environmental experts speak a language you don't understand or continually reject new fluids you would like to use? Or perhaps you would like to use new or improved lubricants, cleaners, rust preventives, or detergents, but the products you've tried have failed the waste treatment tests.

	Key design principles for successful deep drawing By: Art Hedrick, Contributing Writer Successful deep drawing depends on many factors. Ignoring even one of them during die design and build can prove disastrous. Publish date: May 30, 2001 Tech cell: Tool and Die
	Toolmaker tricks By: Art Hedrick, Contributing Writer It is not unusual for me to perform a few magic tricks when holding a conference on stamping die drawing, troubleshooting, or processing. Later on, I may disclose the magicbehind the trick. I do this for a couple of reasons: first, to entertain the conference attendees, and second, to show them that there is no such thing as magic, only physics.

	Using finite element analysis to roll-form tubes By: Karan Shah, Yingyot Aue-u-lan, and Taylan Altan, Contributing Writers Roll forming is a common method for producing steel tubes. It is a continuous process in which a strip is guided through several sets of rolls that form the strip into the desired shape. After the final shape is achieved, tube edges are welded together to form a closed section. After the welding operation, the tube is sized through another set of rolls to obtain the required diameter. Publish date: October 9, 2003 Tech cell: Tube and Pipe Fabrication
	Choosing the right oxyfuel gas and supply system By: David Bell, Contributing Writer Mixing 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. Publish date: November 6, 2003 Tech cell: Arc Welding
	Shielding gas consumption efficiency-- Part I: Spend a penny, save a dollar By: L.R. Standifer, Contributing Writer Installing a bulk delivery system in your welding shop is perhaps the best way to save money Publish date: February 19, 2001 Tech cell: Consumables
	Examining electric resistance weld nuggets in tube and pipe: Using the microscope to study weld characteristics By: Lew Warren, Contributing Writer An in-depth examination of electric resistance welding nuggets as a quality control step in the manufacturing of high-strength tube and pipe used for pressure applications Publish date: April 24, 2001 Tech cell: Resistance Welding
