2 NST(Norsk Sveiseteknikk AS) was established in 1991, enabling us to offer you over 20 years of experience in the welding industry. NST now represents Nippon Steel & Sumikin Welding in three world regions, and we are still growing. Our main products has been NSSW (Nittetsu) seamless flux cored welding wires and ceramic backing for one sided welding, but our product range has been expanded to meet the growing demands from our customers. NST will give you good technical and practical support, with safe deliveries from our large warehouse facilities. Our slogan is Perfect Welding, and with perhaps the highest quality products available today, we at NST are ready to back this up. 1

6 NSSW(Nittetsu) seamless, flux cored and metal cored wires. Seamless, flux cored wires from the first time they were developed - have continually been adapted to new conditions and demands from our customers. Our innovative seamless flux, and metal cored wires unique properties have been developed in step with the renewal of production techniques. The excellent properties are achieved by welding the outer metal layers, joining the seams together and perfectly sealing the flux inside at the time of production. This technique prevents post production atmospheric moisture absorption as well. The biggest advantage with NSSW seamless wires is its extremely low hydrogen content, achieved with heat treatment as an important part of the production process. Low hydrogen content. Extremely low moisture absorption. Low diffusible hydrogen content. Advantageous for the prevention of low temperature cracking. Stable targeting properties, suitable for mechanized/robotic welding. Excellent wire feeding properties. Copper coating and symmetrical crosssectional shape results in excellent wire feeding properties, and tip abrasion resistance. Excellent corrosive resistance. 5
