About us
Our History, at the Service of Your Future
Past
Since 1986, we have been building solutions for resistance welding..
We started as a small family-run company, designing simple machines with a clear goal in mind: to solve real production problems with robust, functional solutions, combining technical expertise with an entrepreneurial spirit.
Over the years, every project has been an opportunity to grow—from the first rotary tables to multiple spot welders, from robotic welding guns to our flagship product: the Marta System cartesian Robot.
We have gained specific and cross-sector know-how, working side by side with automotive manufacturers, wire products specialists, and metal furniture producers across Europe and beyond.
Each machine, each system, each challenge has taken us one step further, allowing us to turn our experience into tangible value for our customers.





Present
Today, we design and manufacture turnkey welding systems, fully customized to meet your specific needs.We manage every step in-house, from mechanical and software design to final testing, thanks to a skilled and responsive team.
Our machines stand out for their flexibility, speed, and reliability. We work alongside our customers to solve everyday production issues such as:
- Reducing cycle times
- Managing different products with a single system
- Automating processes that previously required manual labor
- Avoiding downtime and boosting productivity
- Ensuring consistently strong and reliable weld quality in their products
Future
We continue to innovate , offering solutions that are increasingly high-performing and safe, with a growing focus on automation and process sustainability.
Our goal is o enhance your competitiveness: helping you simplify today’s work while building the factory of tomorrow.
Whether it’s a new system, the optimization of an existing process, or fast technical support, we stand by your side to turn every project into a real advantage.
Our history
On June 26 the brothers Mario e Roberto De Vivo decided to leave the Company founded with their father Arturo De Vivo, and to create a new Company mainly engaged in welding.They joined togheter their respective experiences, coming from the commercial cooperation with other historical Companies, and they founded GEM that began dealing with Resistance, MIG and MAG welders.
In January 1987 GEM rented a premises of 400 m² in the industrial area of Venaria Reale (To).
Two mechanical fitter were appointed for assembling the machines.The first special machines with turntable and the multiple welders for the reinforced doors were designed and built.
In April 1989 GEM took part for the first time in a national Fair named “New Technologies ” into the Halls of the Valentino Park in Torino.
1990. Inside the premises the technical offices were built, housing the technicians charged for designing and managing the commissioned orders.
GEM signed a cooperation agreement with Robot Ind., italian distributor of Motoman.
In October 1992 GEM moved to the industrial area of Robassomero where a premises of 1000 m² with 200 m² of offices was built.
1994 The first prototype of the Marta System, the product that characterizes the GEM’s production in the coming years, was built.
1995. The first Robot Guns of the series GPLF and GPRF were built.
1996 RRRobotica's first Marta System 6-axis numerically controlled robot is born. In the same year, the first robots in the GPLF and GPRF series are built.
In September 1997 GEM took part to its first international Fair of Essen in Gerrmany and established the conditions for building Customer and Dealers network which now are patrimony of the Company.
1999 GEM acquired for the first time an important order in the automotive field. There were nr.45 multiple spot welders machines for assembling parts of the body of the new Fiat Punto.
2000 GEM was ascribed the Quality System ISO 9001, pursuing the policy of ” Customer satisfaction ” all along practiced.
2001 GEM was still growing and new facilities were required. Further 1000 m² for the production and 160 m² for offices were added.
2002 The first automatic electrode dresser of the series G30 was built.
2004 The first fully electric Marta System was born. There were 9 interpolated axis which work on 3D for the welding of wire baskets.The machine was exhibited in Germany at Wire &Tube, the most important Fair in the world in wire and tube field.
2006 The Customers research of machines more and more versatile helped GEM to the development of the first automatic revolver cell, for the welding of nuts and screws for car parts.
2005 Following to the requirements of the automotive industry, GEM designed and manufactured a revolutionary automatic Gun changing system, essential accessory for robotic cells.
2007 In order to weld mesh with dimensions 2000 x 1000 mm on two working stations, the series Marta Modul was born, used later on even for the projection welding of nuts and screws.
2010 Marta System with the new integrated safety robotic techology, developed by GEM in con co-operation with Keba and Bosch Rexroth.
The new Marta System 9ax was exhibited at WIRE 2012.The machine had been fully renewed in the mechanic and in the electric system, the performances in welding quality and speed have been increased of 30%.
The November 2015
Enlargement of the plant with 500 sqm. For the production area and 100 smq. For offices
The June 2017
Increase of the manufacturing area with 5 new 5 axes machining centers
The December 2017
Opening of the new Camss plant in Volpiano – 120 smq of offices and 3.000 smq of production area.
The November 2019
Gem attends for the first time at the Germany Fair Blechexpo-Schweisstec in Stuttgart, Germany
