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.
