Electron beam or laser beam welding?

August 2, 2016 | By John DeLalio

Both laser welding and electron beam welding produce extremely high quality joints. Many consider laser welding first, simply because it’s less costly in many circumstances—but not all. Which to choose depends, as always, on the job at hand.

Clamp, enclose, laser-weld

June 23, 2015 | By Tim Heston

Laser welding works extremely well, as long as you have the right enclosure, keep a clean environment, and make sure you have proper clamping to maintain a consistent gap between your base metals. One laser welding technology tackles all three of these challenges.

How project management drives manufacturing success

June 23, 2015 | By Tim Heston

Manufacturing is no longer about making millions of this or that for years on end. It instead entails a team of experts who get together to tackle a project—or, in reality, many projects at once. This exemplifies modern metal manufacturing, and at Duggan Manufacturing, it happens every day.

Fabricator turns up the heat

June 1, 2015 | By Eric Lundin

When A.O. Smith, the company known for developing the glass-lined residential water heater, had a bottleneck at its resistance welding station and sought an alternate welding method. It had been making a lap welding on galvanized steel by resistance welding, but this trapped vaporized zinc; escaping vapors weakened the weld. A new method, a butt weld performed by laser welding, doesn’t trap the vapors, leaving a visually appealing weld that is essentially free of defects.

Heat it where you need it

May 5, 2015 | By Eric Lundin

Before Thom Shelow founded Superior Joining Technologies Inc., he did quite a variety of welding, but his welding experience wasn’t the only asset he used to make the business a success. He keeps an open mind and is always ready to analyze new ideas, new concepts, and new technologies. “That’s the way we’ve always done it” doesn’t prevail at SJTI.

Technology considerations for laser welding tubes and pipes

March 17, 2014 | By Bill Weston

Using laser welding for making tube or pipe on a mill is a proven technology, but and advancements in tracking systems and controls have made lasers easier to use than when they were first introduced. However, this doesn’t mean that swapping gas tungsten arc welding (GTAW) or plasma welding for laser is simple. Thinking about changing over to laser requires an understanding of how the laser welding process differs from GTAW and plasma welding, and how the various lasers differ from each other.
