About us

NST (Norsk Sveiseteknikk AS) was established in 1991 and are today one of very few Norwegian-owned companies in the welding supply business.
NST represents Nippon Steel & Sumikin Welding (NSSW) in three world regions (Europe, North America and Asia).
Our main products has been seamless cored welding wire from NSSW and ceramic backing for one sided welding.
Offshore- and shipyards have been the dominating customers in domestic and foreign markets.
The product range has expanded over the last years to cover the growing demands from our customers.
We can now offer a complete lineup of welding consumables, and complimenting products for the welding industry.

After establishing in Norway in 1991 there was a need to follow customers out to new European markets, and to develop NST generally.
This resulted in establishing NST Welding (UK) Ltd in 1996, NST Polska Sp.Zo.o (Poland) in 2005, NST Welding Asia PTE.LTD (Singapore) in 2011,
and NST America in 2018.

In Hokksund, Norway we have our Central Warehouse, sales Dept., and headquarters. NST also has a department in Tresfjord.
These branches are full suppliers to the welding business with a diverse range of equipment, such as welding machines, welding supplies, personal protection gear, gas purge systems and pipe handling equipment.
In autumn 2006 we opened our own warehouse in Norway. This service has been outsourced since the start in 1991.
NST now has full control of its own value chain in Europe.

NST has a highly qualified staff holding IWE (International Welding Engineer), EWE ( European Welding Engineer) and CEWE (Certified European Welding Engineer) qualifications, enabling us to offer full technical support as well as practical welding demonstrations and training as required on site, NST have experience in providing special training programs tailored to the needs of individual companies.

With over 20 years of experience NST can offer very 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 in the market today, we at NST are ready to back this up.
