Stainless steel welding and high requirements on the part of the Base Group clients are an opportunity for them to develop and have the chance to produce more and more interesting constructions. In connection with new projects in the power sector, Base Group have developed and implemented a new welding technology (WPQR- Welding Procedure Qualification Record) which makes it possible to perform welding of stainless steel materials up to the thickness of 40 mm. The new technology of welding (WPQR) is developed at Base Group by specialist in the field of welding, that is by welding engineers (both EWE -European Welding Engineer, as well as IWE, International Welding Engineer).
Before the new technology of welding was developed, both technical documentation and the contractual requirements were analysed in the first place, so that there was absolute certainty and guarantee for the quality of the steel structure made. The semi-automatic welding technology (MAG, Metal Active Gas) was conducted under the supervision of a certifying body TUV Sud in accordance with the requirements contained in the standard EN ISO 15614-1, standard DNVGL-OS401 and the Pressure Directive PED 97/23/EG.
