That involved making thousands of holes with a router. Yli-Tokola also finished the sides of the fish by hand. For instance, I bent the tail of the pike to shape by heating the sheet metal to a red glow and shaping it with a sledge hammer and hammer,” he explains. “Most of the work had to be done by hand. The sides of the pike were made of a 40 mm thick sheet while the tail was made of a 20 mm thick sheet. Plater-welder Marko Yli-Tokola, who was in charge of the production process, estimates that he spent around two thousand hours on the project. The other parts of the sculpture were made at Halikko IKP Works Oy. © Jenna Lehtonen/Savon Sanomat Unique workmanship Jyrki Roivainen and Tommi Sinisalo worked on the head of the pike for around two years. In 2012, Kemppi replaced the Kempomat range with the new Kempact RA range, which was recognized with the prestigious iF product design award soon after it was introduced. #KEMPPI KEMPOMAT 3200 MANUAL PROFESSIONAL#You also had to be patient and give the pieces time to cool to avoid burn-through.”Īll welding was done with Kemppi’s Kempomat 3200 machine equipped with a push-pull gun which made wire feeding more efficient. Ever since their introduction to the market, the world-famous Kempomat machines have been popular MIG/MAG welding devices among professional welders. “The weld seams had to be ground and finished to look exactly like the rest of the sculpture, which meant that all weld beads had to be removed. “It was a great achievement.” According to him, the secret behind the successful completion of the project was the right welding machine settings and patience. He was relieved when the challenging project was completed. Sinisalo was one of the welders who joined the head of the pike to its body. “Now we are all very good at welding aluminum.” The welders’ skills in aluminum welding developed as the project progressed. In total, 20 feed rolls of 1.2 mm diameter aluminum wire were needed to complete the project,” he says. “We had one to three men working on the pieces for two years. Sinisalo does not dare to think of the total amount of hours spent on the welding work. The head, weighing 700 kg, and the firewood piles were welded together using aluminum. Sinisalo recalls that 1,600 kg of plaster was used to make the molds. The head of the pike is made of 70 separate cast pieces. “Welding and finishing the teeth in the upper jaw of the pike took several days,” Tomi Sinisalo of Lapinlahden Taidevalu Oy says, shedding light on the scale of the project. This stage of the project alone took two years. The head of the pike and the five firewood piles were cast at the Lapinlahden Taidevalu Oy’s foundry. The making of the 50,000-tonne sculpture required more skill and time than anyone would have thought. The artwork measures six meters in width and nine in length. Next to the pike are two towers made of the lids of concert grand pianos and piles of firewood. The pike at the center has alder branches entwined around it. The totem-like sculpture consists of three parts. However, both its makers and Hukkanen himself let out a sigh of relief when it was erected in August 2012. The sculpture made of aluminum and steel has proven exceptionally popular. The Laulupuut (‘Song Trees’) artwork, designed by sculptor Reijo Hukkanen, also extends around the pike. 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.
