How We Work

Orbital Sanitary Welding

Orbital welding technology for automated and homogeneous joining of stainless steel tubes, reducing human interference and increasing traceability.

How We Work

Technical Execution with Field Control and Compliance Focus.

Orbital welding technology allows automated and homogeneous joining of stainless steel tubes, reducing human interference and increasing traceability. We use calibrated and certified equipment per ASME BPE standards, ensuring repeatability and superior finish. Ideal for high-purity systems, this technique elevates installation quality and durability.

Frequently Asked Questions

Clear Information for Those Seeking a Reliable Technical Partner.

Top questions about our processes, standards, documentation, and service.

Does Montech provide the full data book for the work performed?

Yes. All our installations are delivered with a complete technical folder (Data Book), containing material certificates, welder qualifications (WPS, PQR, IQR), weld maps, borescopy reports, and hydrostatic test certificates.

Which technical standards do you follow for stainless steel welding?

We operate under international standards such as ASME BPE (Bioprocessing Equipment) for sanitary systems, AWS D18.1/D18.2 for food/pharmaceutical applications, and ASME IX for general pressurized system qualifications.

Is it possible to integrate weld traceability with our ERP?

Yes. Our internal traceability system can export data in digital format (XML, CSV, PDF), facilitating integration with industrial ERPs, maintenance software, and BIM platforms.

How is thermal control performed during orbital welding?

We monitor current, voltage, speed, and heat input profiles in real-time, with parameters recorded electronically in the equipment. This ensures repeatability and constant quality across all joints.

What criteria does Montech adopt for welder and procedure qualification?

We follow ABNT NBR ISO 9606-1 and ASME IX standards, performing mechanical tests, visual inspections, dye penetrant tests, and macrostructure analysis, ensuring total compliance before execution.

Do you offer technical support during FAT/SAT or system start-up?

Yes. We provide technical support during FAT (Factory Acceptance Test) and SAT (Site Acceptance Test), ensuring that all lines and connections are within the specified performance parameters.
