Good welders are hard to find and this problem will get worse in the future. But that's not the only reason why companies with welding departments would like to automate some of their jobs. Another reason is that when you weld for hours on end, your concentration wanes and quality can suffer considerably as a result. However, what keeps many potential buyers of welding robots and welding cells from making a purchase is the complexity of these machines. Especially for small series, the effort of programming is often not worth it. In addition, programming requires in-depth knowledge of welding technology, which in turn calls for a well-trained welder.

So some people ask themselves: Why isn't there an automated welding cell that is easy to program, has many parameters already integrated, and is in a lower price segment despite high quality demands?

Naturally, Andreas Zweifel immediately took notice when Patrick Kühne, customer service representative at TRUMPF Switzerland, told him on the phone about the TruArc Weld 1000 - an automated welding cell that combines all of these sought-after features. Still on the phone, the Managing Director of the family-business zweifel metall ag confirmed, "I want a machine like that at our company!"

Kühne has fond memories of the phone call: "I don't often sell machines directly over the phone," he laughs, "but I thought that a metalworking shop with 14 welding tables might well have a need for an automated solution that offers a price/performance ratio as good as that of the TruArc Weld 1000."

"In general, care was taken with the TruArc Weld 1000 to maintain a customary high TRUMPF quality standard, combined with simplicity throughout," explains Patrick Kühne. This is evident, among other things, in the programming: It is a combination of an intuitive operating unit on the welding torch as well as simple programming directly on the robot controller for minimal programming times. In addition, the parameters for many welding programs are already entered.

ECONOMICALLY ATTRACTIVE EVEN WITH LOT SIZE OF 1

The fact that zweifel metall ag would also benefit from the robot's efficiency was therefore out of the question - and this became apparent very early on. Because even before the TruArc Weld 1000 was in the halls of zweifel metall ag, an inquiry came in, which they calculated as always for manual welding. But because the new welding cell was already installed in the hall when the order started, the parts were welded on the TruArc Weld 1000. The time saved - including programming and reworking - was more than 50 percent less than calculated in the original order! Another factor contributing to the time savings is that the welding cell can be converted into a 2-station operation thanks to a retractable partition wall, allowing the operator to set up parallel to production.

SET UP, READY, GO

Isn't TRUMPF asking too much of its customers? Patrick Kühne wanted to find out for himself. When the machine was to be delivered, Kühne told Andreas Zweifel, "I don't want to just be there to see if it works, but I'll set up the machine for you myself!" No sooner said than done. The former machine fitter was there in his "Übergwändli" (Swiss-German for cover-alls) on the day of delivery, and less than two hours later the machine was leveled, connected and ready for operation at the designated location. "There were no problems. My company really didn't promise too much," says Kühne happily.
