Rolex fixed by welding
5 марта 2019 г.
A Norwegian Rolex owner saved a fine sum of money when the wristband of his valuable timepiece was fixed by welding. The owner tried to take the watch to various watchmakers in Oslo to have it repaired. Several attempts were made to fix the wristband by, for instance gluing, but they all failed. One of these craftsmen suggested welding to fix the wristband but did not want to try it himself, in case the heat was to cause even more damage.
Welding Value
The new wristband for the valuable watch would have cost 1 500 euros. A less expensive option was to find a professional with sufficiently high-quality welding equipment. The watch owner contacted Øivind Myhre at Svinndal Gjerde & Sveiseverksted, who was attracted by the unusual challenge. He asked to have pictures of the wristband and set out to look for practical solutions for repairing it. After doing some research on the subject, Myhre discovered that the Kemppi MasterTig MLS ACDC and its MicroTack function in combination with the ACS control panel offered a solution for fixing the Rolex wristband.
Perfect connection
The wristband and its fastener were dismantled and the components cleaned of old glue and dirt. Myhre also practiced with his colleagues in advance by performing welding tests on stainless steel wire with a diameter of 1 mm.
"In the first welding test we used sunglasses and a lamp equipped with a magnifying glass," explained Myhre. "After a few spot welds, we understood that the materials of the wristband and lock behaved slightly differently from those that you normally handle by tack welding. By increasing the welding current to 135 amperes and adjusting the distance to the welding piece to 0.5 mm, the desired result was attained. The pieces were perfectly connected."
Myhre finds the result astonishing and sees limitless possibilities for performing similar special tasks with an array of Kemppi’s machines. Understandably, the happy Rolex owner praises the professional skill and flexibility he encountered at Svinndal Gjerde & Sveiseverksted.

50 years of partnership between a man and a welding machine
In the 1960s, there was a huge shortage of professional welders in Finnish growth centers. That is why Keijo Olkoniemi, whose career as a welder has lasted for almost 50 years, trained to become a welder, a profession which has offered him challenges throughout his career. ”I remember when they said at the dockyard in Hietaniemi, Helsinki that you can bring a train full of skillful employees, and we will hire them all,” Olkoniemi says, laughing.

The making of 'Laulupuut' welded sculpture
A 13-meter high giant pike singing with its mouth wide open now occupies a prime location at the square in front of the Helsinki Music Centre in Helsinki, Finland. The Laulupuut ('Song Trees') artwork, designed by sculptor Reijo Hukkanen, also extends around the pike. The sculpture made of aluminum and steel has proven exceptionally popular. However, both its makers and Hukkanen himself let out a sigh of relief when it was erected in August 2012.
