Ingeniero Jonás Paiuk Paiuk en su hogar,trabaja y evoca sus 42 años en Techint.


Graduated in 1958 in Electrical Engineering at the University of Buenos Aires. Joined the same year the group at the Dept. of Electronics of the University, which designed and built the very first transistorized computer in Latin America, while simultaneously pursuing a Degree in Electronics.

In 1960 become part of the by then new Institute of Calculus of the Faculty of Sciences,

under the Direction of Dr. Manuel Sadosky and Dra Rebeca Guber, where up to 1966 was responsible for the Engineering group which designed, installed, maintained and developed Engineering applications for the Mercury Ferranti computer, the first scientific computer to be installed at the University of Buenos Aires.

Joined Siderca (Integrated Seamless Steel Tubes Producer for the Oil and Gas Industries) in 1966 where was responsible for:

Mid sixties

Supervising the installation of the instrumentation, process control computer and electronic power drives of a complete finishing line which included a 24 stand stretch reducing mill after the three pilger mills, a highly complex and accurate flying saw, transfer lines, straighteners, etc. Responsibility included the completion of the computer models used to run and optimize the set-up of the 24 stands of the stretch reducing mill (speed, profiles of the rolls, set-up of the cutting machines in order to get the proper profiles for each reducing stand, torque and power calculations for each stand).

The responsibility included (since that was the very first installation of its kind at Siderca) the selection and training of the maintenance personnel, the set-up of an Electronic Laboratory and the follow-up and improvements through the years.


Started-up the Process Control and automation Division, which designed, built and implemented one of the very first world wide system for automatically measuring the length and weight of tubes, control the metric weight, stamp it and stencil it with the appropiate leggend, generate the corresponding tallies, and update the status of the order. The system was so succesfull that TESIS (Techint-Sistemi- a smaller Techint Company) build and sold world wide more than 20 systems based on that design. Which kept being continously improved through the years.

Actively involved in the steel making process control, designed and implemented a sophisticated integrated control system for the electric arc furnaces, which are continuously fed reduced iron pellets as well as steel scrap. The control and supervision system extended thereafter to the conticasters and to the design of the quality on line control and supervision systems. The basic concepts have been later incorporated by Krupp (under a specific contract) to one of their steel mill projects.

Introduced the CNC control system concepts to the next generation of thread cutting lathes. Again this implied the technology selection, personnel training (operators and maintenance) and supervision and follow up, as well as the design and follow up of the cutting programs of the API threads.

Responsible for the Instrumentation, drive systems, control systems, computer control and overall supervision of the LACO 1 project, a Floating Mandrel Continuous Mill, started up in 1976. It included for the first time in such a project, the intensive use of PLCs (programmable logic controllers). Quality control supervision being part of the system, assuring the integrity of the product. As well as the use of Hewlett-Packard Real Time Computers for the calculation and Control of the On Line Set-Ups for the Hot Rolling Mills based on Mathematical Models.

Responsible for the analysis, design, start up and follow up of the Non Destructive Inspection Lines within Siderca. Created the concept of using the principle of High Frequency High Power Diverted Flux for the proper identification of small (5%) outside defects on tubular products, successfully implemented in almost all of Siderca? inspection lines. Also responsible for the system approach to the design of the NDT lines.


Design, implementation, start up and follow up of the Fully Automated Quench and Temper Line for Tubing which includes a fully automated inspection line.

Responsible for the conceptual design, instrumentation, process control, computer control including the development and improvement of the mathematical models controlling the reheating furnaces, piercing mill, continuous mill, intermediate reheating furnace, sizing mill, cooling and transfer beds, cutting systems, joint identification systems, including the overall supervision and tracking systems of the new Laco 2 Casing Mill. The start up of this mill in 1988 proved to be extremely successful and enabled Siderca to position itself as a prime supplier of high quality OCTG on a world wide basis.

Mechanical and system redesign of the NDT ultrasonic inspection DAPCO system, having introduced some novel ideas with reference to the ultrasonics and mechanical handling devices.

Designed and implemented a highly sophisticated and automated continuous finishing line for Casing products. Starts by the thread cutting Pipe Machinery, continuing with thread inspection, coupling positioning and make up, hydraulic testing, cleaning, dewatering, protector insertion, and finally length measuring, metric weight testing, marking, stenciling, tallying, varnishing, drying and packing.

A similar line was designed and built for Tubing products.


Become a member of Ditec, Technical Direction of the Techint Industrial Group of Companies. As such, responsible for the follow up and advice in the main areas of Inspection, NDT, Instrumentation, Process control, Automation. Having been intensively engaged in the redesign of the Process Control Systems of the Blast Furnace # 2 and the Hot Rolling Mills at Siderar (Integrated Plate Producer for the Automotive and White Products Industries).

Continuously active at the professional level, Chairman of AADECA (Argentine Association for Automatic Control) which is also the National Member Organization of IFAC (International Federation of Automatic Control) during several periods during the last thirty years..

Was Chairman of the 6th International IFAC Symposium for Automation in the Mining and Steel Industries’1989, Sheraton Hotel Buenos Aires, where more than 200 international specialists in this area participated.

Acted as officer of IFAC (International Federation of Automatic Control) during the period 1993-1996, being held responsible for the LCA (Low Cost Automation) Committee.

Executive Council member of IFAC, 1996-2002 period. The Executive Council is composed of just 12 international members.

Organizer of the 7th Latin American Control Conference and Exhibition that took place on the week of 9-13th of september 1996 (Sheraton Hotel Buenos Aires). It is the most important of its kind in Latin America. More than 240 presentation have been presented.

Actively participated at Technical ILAFA (Latin-American Iron and Steel Institue) meetings dealing with Process control in every area of steel and tube production and quality and NDT inspection methods and systems.

During the eighties and nineties participated actively at API (American Petroleum Institute) and ISO meetings, specially in the Work Groups dealing and handling with NDT of Tubes for the Oil and Gas Industries.

During 2002 and as Chairman of AADECA, organized the 18th National Instrumentation Control and Automation Conference together with the 15th Exhibition of Instruments and Control Systems that took take place the first week of September 2002 in Costa Salguero Place, Buenos Aires.

V.P. Of the ORT Technical Schools in Buenos Aires ( 4000 Students in the Junior and Senior High School and 2000 at the College Level) during 2002.

Since 2001 and up to the present acting as Consultant to the Tenaris Group (seamless steel tube integrated producer) with 9 mills spread all over the world.

Since January 2005 advicing the RRHH Director of Tenaris in the areas of Knowledge Management and E-Learning.

As well as in establishing a Corporate University for the Tenaris Group of Companies. Named TUAS (Tenaris University Advanced Studies)

Member of the Board at ORT Argentina and Member of the Board of Directors of World ORT. Participating on the committees dealing with strategic planning and laws and bylaws.

Elected in the last International ORT World Meeting of the Board of Directors in Iam Hamelaj, January 2005 as Chairman of the Technology and Education World ORT Committee.
