Get your schedule in order: How first- and second-order decisions affect resistance weld schedulesThe 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.

Getting close to remote laser welding: Research reveals that the technology is a reasonable alternative to resistance spot weldingRemote 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.

Projection welding for nut and bolt attachment: Competing or complementary joining methods?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.

Resistance-weld more for less: Best practices prolong electrode lifeCosts 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.
