Choosing between a welding track carriage and a magnetic welding carriage is not simply a matter of choosing the more automated machine. The better choice depends on the workpiece material, weld location, surface geometry, pipe...
When a fabrication shop searches for a magnatech orbital welding machine for large-diameter pipe girth welding, the first question should not simply be “Can the machine weld large pipe?” The more useful question is: Which Magna...
Industrial condensers can contain hundreds or even thousands of tube-to-tubesheet joints. For manufacturers, the challenge is not simply welding one joint successfully. The real challenge is completing a large number of joints ...
I have walked through a lot of equipment factories over the years. Some are assembly shops that bolt together components from other suppliers. Others are real manufacturers—they machine their own parts, test their own...
I remember a shop foreman in Ohio holding up two tubesheet samples. One had a tube that dropped into the hole with almost no resistance. The other required a rubber mallet. “Same drill bit,” he said. “Same operator. Two differe...
I remember a call from a fabrication manager in Texas who was convinced he had the answer. "We qualified one procedure five years ago," he said. "We've been using it on every heat exchanger since. Why would I need ano...
I remember standing in a boiler shop in Ohio a few years ago, watching three different welders work on the same tube bundle. Each one had their own technique. One ran a tight arc and moved fast. Another held a longer arc and to...
I remember walking through a boiler fabrication shop in Pennsylvania a few years ago. The production manager stopped me in front of a massive tubesheet—over two meters across, with hundreds of tube holes staring back at us. “Ev...
I remember watching a radiator shop in Ohio struggle with a batch of 500 industrial cooling cores. The tubes were thin-walled copper, the header plates were brass, and every single tube-to-header joint had to be leak-...
