	Gaining control of resistance welding: Weld monitors deliver means to benchmark and verify the weld process and equipment By: Geoff Shannon By providing time-based waveform data on current, voltage, resistance, power, force, and displacement—as well as peak and RMS values—external weld monitors are able to provide the necessary data that can be used to understand, optimize, and benchmark the resistance welding process and verify accompanying equipment Publish date: August 8, 2007 Tech cell: Arc Welding
	Get your schedule in order: How first- and second-order decisions affect resistance weld schedules By: Bob Szabo The quality of resistance-welded components depends on the weld schedule, which comprises several machine settings. Although many resistance welding machine and electrode suppliers offer standard weld schedules for common metal combination, special weld schedules often are necessary to address increased use of special metals, joint combinations, coatings, and weld-through sealants and adhesives.

	A new way to weld sheet metal: Remote laser welding replaces spot welding in microwave oven fabrication By: Steve Southwell and Robert Kloczkowski Nu-Way Industries Inc., Des Plaines, Ill., learned that remote laser welding demonstrates impressive advantages over traditional resistance and arc welding for its applications. Publish date: March 7, 2006 Tech cell: Laser Welding
	Getting close to remote laser welding: Research reveals that the technology is a reasonable alternative to resistance spot welding By: Robert Mueller Remote laser welding is a fairly new kid on the block in terms of joining metal in North America. But it makes complete sense for those high-volume applications where resistance spot welding is used commonly. Publish date: June 26, 2009 Tech cell: Laser Welding
	Mode of least resistance: Understanding control modes in resistance welding By: Girish Kelkar, Ph.D With the advent of transistorized controls in resistance welding, power supplies are available in which feedback can be used to control current, voltage, or power delivered. The use and benefits of these control modes are not well understood, leading to underutilization of the technology. It is important to understand the fundamentals of the control modes as applicable to DC and inverter power supplies and the special situations that you might encounter in their application.

	Projection welding for nut and bolt attachment: Competing or complementary joining methods? By: John Larsson Projection welding, also known as resistance fastener welding, is the most common method for nut and M- or T-thread bolt welding. This article examines recent experiments with projection welding of those components to various high-strength steel components. Publish date: February 12, 2008 Tech cell: Resistance Welding
	Respecting your resistance welder: Avoiding downtime with preventive maintenance practices By: Tom Snow Resistance welding results are only as good as the machine that is completing the process. By understanding how to properly maintain your resistance welding machine, you will be able to prevent unnecessary problems that tend to plague the unit's critical areas.

	Resistance-weld more for less: Best practices prolong electrode life By: James L. Dillard Costs associated with poor resistance weld quality often can be traced back to faulty electrode usage. With today's high cost of copper—to say nothing of the extra labor and lost production time—wearing out electrodes prematurely has become more expensive than ever.
