Welding method qualified
Since 2010, the welding method used at Hendriks precon has been qualified from 5 to 30 mm, up to and including steel S355 with the corresponding qualified welders under the 9606-1 standard. In addition, we employ welders who specialise and are certified in high tensile strength steel types and concrete steel in the 135 process.
Furthermore, we have been certified for the WPQR-NPR 2053 since 2014.
All our field workers/welders are certified for welding process 111 (electrode) in the most common welding positions and basic electrodes. This way you can rest assured that onsite work is also carried out in accordance with the latest standards and requirements.
