You can plasma cut it, but can you weld it?: Plasma cutting with the right gas and torch setup makes life easier for the welderTime spent on extensive weld prep easily can eliminate any gains made from faster plasma cutting. Put another way, it doesn't matter how fast a plasma cuts if the resulting cut face can't be welded efficiently.

Efficient use of compressed gases can increase productivity: Part I. Overview of compressed gases used in the metal fabrication industryThe metal fabrication industry has used compressed gases for more than one hundred years. Oxy-fuel cutting and welding have existed since the beginning of the 20th century. The more automatic welding processes, such as gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW), began as early as 1920.

Virtually welding: Training in a virtual environment gives welding students a leg upToday several companies offer technologies that help beginning welders get that hand motion just right. None claims that the technology will replace the real thing, of course, but they do say that training in the virtual world can give students a significant leg up by the time they weld for the first time. It helps teach students what really happens between the welding arc and workpiece, why certain hand motions produce good beads while other motions don't. And it also may help introduce welding to students who wouldn't have given the trade a second thought.

Modified GMAW for root passes: Modified process improves results on stainless, carbon steel pipeMany fabrication shops that do a lot of stainless steel tube and pipe welding are in a bit of trouble these days. The problem isn't a lack of work, of course—it's a matter of trying to handle too much work with too few resources (skilled welders). They can ask their fabricators to work harder or faster, but that goes only so far. Can a new technology help them get more output from their existing employee base?

Automation in tube and pipe welding: Robots make sense for many reasonsRobots make a lot of sense for tube and pipe welding. The return on investment for a typical robot system can be seen usually within six to 24 months, depending on the parts, complexity of the system, and learning curve of the manufacturer. Quality improvements are typically seen immediately. In addition, by tracking the process, manufacturers can make changes to improve production time and determine the throughput of the system for accurate part production projections.

Keeping consumables from consuming welding profits: New welding tips help truck, trailer manufacturer cut costsLike every manufacturer these days, truck and trailer manufacturer Tico Manufacturing Inc. can't afford to waste any time on non-value-added activities. It recently switched its welders to Centerfire™ nonthreaded contact tips manufactured by Bernard®. These tips require replacement about once every two weeks; the previous tips were replaced three times a day. And because they are unthreaded, the tips take much less time to replace.
