CEMSA, 50 years of welding and automation expertise

Flexibility, creativity, and a selected supply chain of Italian vendors enable CEMSA to operate in over 120 countries worldwide. The company serves highly demanding sectors such as automotive, aerospace, and white goods manufacturing—industries where process control and technological integration are essential.

Over five decades, CEMSA has positioned itself as a specialist in resistance welding, electro-upsetting, and turnkey automation systems designed to meet complex production requirements.

Process control and certification in welding production

Across industries, manufacturers share common requirements: precise monitoring of the welding process and certified quality of welded or electro-upset components.

As tolerances become tighter and quality standards more stringent, every weld spot must comply with defined mechanical and metallurgical parameters to ensure structural strength, operational safety, and long-term reliability. CEMSA develops advanced process control systems that guarantee real-time monitoring of welding parameters, full traceability of each production cycle, data acquisition and storage for quality certification, and repeatability across high-volume production batches.

Each welding cycle is recorded and controlled, providing customers with documented proof of compliance and process stability—an increasingly strategic asset in regulated sectors such as aerospace and automotive.

From resistance welding pioneer to integrated system supplier

Founded in 1976, CEMSA began as a resistance welding specialist with a clear international outlook. In the late 1970s, the company introduced its first CNC resistance spot welder, the ROBOROOF, at the Milan Trade Fair—an early example of automated welding technology that anticipated the industry's evolution toward digital process control.

In 2004, CEMSA expanded its technological portfolio with electro-upsetting systems, a hot preforming process frequently used prior to stamping. This addition allowed the company to support increasingly complex applications requiring high material performance and dimensional precision.

Over the years, CEMSA’s philosophy has remained consistent: customers do not simply purchase a machine; they invest in a production solution. The company therefore designs and manufactures complete, customized production systems tailored to specific industrial requirements, integrating welding technology, robotics, automation, and data management.

Application experience across strategic industries

CEMSA’s expertise is reflected in several high-profile projects:

• 2018 – A leading aircraft repair hub in the Middle East selected CEMSA to supply a large-scale spot welding system capable of recording and transmitting process data for each individual weld spot, ensuring full traceability and compliance with aerospace standards.

• 2019 – Development of a roller welding machine integrated with an anthropomorphic robot for the production of SUV fuel tanks for a prestigious British luxury automotive manufacturer.

• 2021 – A California-based customer commissioned a third electro-upsetting unit for the production of titanium valves used in high-performance internal combustion racing engines, confirming long-term confidence in CEMSA technology.

• 2025 – A long-standing Brazilian customer invested in two six-station units for markless cosmetic welding of door lock front plates—an advanced solution combining aesthetic precision and process stability, unique in its segment.

Innovation and sustainability in resistance welding

In resistance welding operations, energy consumption represents a significant share of fixed production costs. Optimizing electrical efficiency is therefore a strategic priority for manufacturers seeking improved competitiveness.

CEMSA has integrated advanced electronic power control systems into its latest machines, enabling energy savings of up to 45–50% compared to previous generations. This performance is achieved through optimized process control, improved transformer management, and precise modulation of welding parameters.

Lower energy consumption translates into reduced operating costs and decreased environmental impact—two key objectives for modern manufacturing plants focused on sustainability and long-term profitability.

For companies seeking advanced resistance welding or electro-upsetting solutions, CEMSA offers customized systems engineered to meet specific production targets and certification requirements.
