Preparing

Our "Welding Quality Assurance" division provides regulatory and normative assessment to address relevant technical solutions to the needs of our clients.

The equipment records files are created, verified and approved internally; then a comprehensive validation process is implemented including our customers and external inspection organisation when required

MONTEIRO Company brings its expertise on welding activities where a quality assurance survey is required in accordance with the following normative & regulatory requirements:

RCC-M / RSE-M / CODAP / CODETI/ NF EN 13480 / NF EN 13445 / NF EN 1090 / NF EN 287 / NF EN ISO 9606 / NF EN ISO 15614 / NF EN ISO 14732 / NF EN ISO 3834 / DIRECTIVE MACHINES / DESP / ESPN / REGLEMENTATION CPP-CSP / ARRETE INB
