Jacques Bonnefon established the company in 1955. His aim was both simple and ambitious : to accompany and to advise welding professionals on the solution that best suits their needs.

Since 1993, Gérard and Daniel Bonnefon, the Group directors, have never turned their back on this family heritage but succeeded in preserving and reinforcing it. Daniel BONNEFON manages the company on his owns now after his brother's retirement. Gaining the trust of major brands, partners or customers, the Bonnefon group takes responsibility for its own development and completes its offer of solutions and services.

From manual welding to robotic welding, the joining techniques and the welding business in general, have evolved considerably.

Health, safety and environmental standards have contributed to fundamentally change the main issues of the welding sector.

All major welding players had to evolve as well. Only highly specialized companies were able to anticipate and to face these changes.

The Bonnefon group has chosen a strategy of hyper-specialization very early, which makes it a major player within the welding sector - locally but also throughout the French territory and internationally.

The Bonnefon group is continuously innovating in order to enhance its differences and its independence.

Because there is nothing but the human contact, to meet new industrial challenges together!

As you will have understood, the Bonnefon group wants to be a true technical partner.

Certainly expert but always close to you locally.
