>> High quality - particularly with regard to the criteria of repeatability and precision - and increased productivity are the key benefits of the automation of welding processes. The components are welded to be joined in high cycle applications, allowing for competitive prices.
The Ten-axis welding robot, which are used in the workshops of the sheet metal industry operating Patric métal SA Geneveys-sur-Coffrane (NE) ensure fast, reliable and regular welding processes. Patric The group heard how the companies LNS SA (Orvin) and Meyrat SA, Nugerol Holding SA. It is made from Patric métal SA, the companies Patric concept SA in Colombier (NE) and Patric inox SA in Marin-Epagnier (NE).
Adaptability in the operational events
When Patric métal two robot welding stations with a total of ten are in the CNC-controlled axes used. Each station includes six axes for the robot part, three axes of the machine base and an axis for the rotor. With this production equipment it is possible to "just in time" to produce (especially for mass production advantage) and to work according to the workflow scheme, "Lean Production". If it is the production of small quantities or fractional jobs, pays the flexibility of the system of special. The final products can be delivered either as individual parts and fully assembled.

Patric métal employs 125 employees and performs all automated welding work, from concept to finished product, provides consulting and project studies, development and manufacture of complete products including paint, assembly and quality control. The premises of Geneveys-sur-Coffrane was expanded last year, this was an automated depository for storage of plates decorated with a capacity of 435 campsites. The system of quality control is currently certified according to ISO 9001 standard.

The robotic welding is not only in itself a guarantee of gaining time. The improved regularity, the higher precision of the parts and the increased productivity made possible above all, there can be used alternately to two welding stations and the welds are checked and edited outside of the production line can, whilst the welding robot to continue working without interruption. The production capacity can be doubled by two welding stations to work simultaneously in the same order independently or edit two different parts costing on home loans used for business..
Consistent production - fast production processes
The use in stationary equipment can perform all welding of components for building or steel (MAG, MIG, TIG or CMT). The parts to be welded are fixed to a socket on the machine (circular numeric axis) custom jig. The welded parts reach lengths of up to four meters in diameter and up to two meters. It is also possible to weld with the aid of holding devices very small parts, and so increase the productivity considerably. Thanks to the spring of 2009 went into operation in welding processes Patric métal dare the step to "integral sheet metal work" and currently provides facilities for automated precision welding of very complex parts. During the plant tour of the MSM editors, the facility was in the booth, highly complex parts with automated welding to connect with each other: it is to roll material support of steel sheets from four to five millimeters in thickness, the weld line was 28 meters. As for the uniformity of the weld, not a single correction or rework was necessary. Each workpiece was processed in less than one and a half hours, including testing and quality control. In relation to the traditional way one time gain is achieved by about 30 percent.
A "vital" part of the process is to program the geometric coordinates of the component to be welded and the holding and positioning device in the system. This is done at a workplace (CFAO station) using 3D models that are created with a design software. The holder is manufactured with great precision, so that the geometric variations of the weld seam are not greater than plus / minus 0.5 millimeters.
Production at competitive price
Many companies in Switzerland have now (mostly) due to cost pressures on outsourcing capabilities. Welded components are mainly in Eastern European countries. But several companies have this philosophy once again thrown overboard after being confronted with insurmountable problems such as poor quality of work or delay in delivery.
With the installation of the robot system with Patric métal there were no complaints regarding product quality, even the prices were compared to those charged by the foreign manufacturers are kept competitive. And in addition, there was an added value: the proximity of production led to trusting relationships between customer and spare part supplier. <<
