The beginning of the welding school goes back to 1937, when Cercul pentru Încurajarea Sudurii (CIS – the Society for the Encouragement of Welding) was created, a vocational association that reunited under the leadership of the academician Corneliu Mikloşi a series of high prestige spersonalities, such as academician Ştefan Nădăşan, academician Remus Răduleţ, and prof. Constantin C Teodorescu.
origin of the of material testing school in Timişoara can be traced
back at the specialized department within the Polytechnic School founded
in 1921, managed in the beginning by prof. C. C. Teodorescu and then,
since 1938, by acad. Ştefan Nădăşan.
Acad. Ştefan Nădăşan
1952-1954 the welding and material testing departments were founded within
the Timişoara Branch of the Academy. These research departments were
part of the Academy Centre of Technical Research Timişoara, together
with the cavitation and the building materials departments, successively
managed by acad. Corneliu Mikloşi, acad. Ştefan Nădăşan,
and acad. Ioan Anton. Since 1957, the Academy Centre of Technical Research
has been the representative of
welding department, managed by acad. Corneliu Mikloşi and, after
his death, by acad. Traian Sălăgean, developed between 1954 and
1970. Within the welding department there were obtained a series of
remarkable results, such as the ones connected to:
material strength department, transformed later on in the Fatigue and
brittlel fracture department within the Academy Branch was managed by acad.
Ştefan Nădăşan and then by prof. Mircea Raţiu.
The research themes of the department were mainly in the field of fatigue
and wear, the fracture and brittle fracture mechanism, fault
detection, and electrical tensometry.
research possibilities within the Technical Research Centre of the Academy
proved to be insufficient from a quantitative point of view, as the welded
structures production developed very quickly. This lead to the foundation in
1970 in Timişoara of the Welding and Fatigue Testing Centre (CSIO),
which later became the Institute of Welding and Material Testing (ISIM).
its foundation, the institute reunited the Welding, Fatigue and Brittle
Fracture Departments of the Academy Branch, as well as the Welding
Workshop of ICTCM Bucharest, with a personnel composed of 51 employees,
under the leadership of acad. Traian Sălăgean as president
and prof. dr. eng. Mircea Raţiu as scientific vice-president.
Prof .dr.eng. Mircea Raţiu
as a technological institute, ISIM continuously developed its field of
activity, so at present it comprises:
fundamental and applicative
research in the field of material welding and allied processes, control
and material testing, and welded structures;
development of new devices
and equipment for welding, cutting, cladding, control, and material
analyses and material
standardization and elaboration of standards in the field of welding and
allied processes, nondestructive testing, and material mechanical
activities of scientific and
engineering counseling, technical expertise, technological services;
production of eqiupment and devices
in the field, with new incorporated principles and solutions;
production of welding
and training of personnel at all levels;
dissemination of scientific
and technical information.
its history, the Administrative Board of the institute was presided by
acad. Traian Sălăgean (since its foundation until 1982), dr.
eng. Zeno Pircea (1982-1990), prof. dr. eng. Dragoş Cioclov
(1990-1994) and by prof. dr. eng. Dorin Dehelean since 1994. As Scientific
Directors there succeeded prof. dr. eng. Mircea Raţiu (1970-1974),
dr. eng. Mircea Hrelescu (1974-1978), prof. dr. eng. Dragoş Cioclov
(1978-1990), prof. dr. eng. Dorin Dehelean (1990-1994), eng. Iustin Furdui
(1994-1998) and dr. phys. Nicolae Farbaş since 1998.
the years, the Institute housed nationally and internationally
acknowledged researchers. We can mention some of them: acad. Traian Sălăgean,
prof. dr. eng. Mircea Raţiu, prof. dr. eng. Dragoş Cioclov,
prof. dr. eng. Voicu Safta, dr. eng. Ioan Arghiade, dr. eng. Clara Boarnă,
dr. eng. Mircea Hrelescu, dr. eng. Ştefan Morariu, dr. eng. Alexandru
Vaş, eng. Ioan Surgean.
the field of research in material joining processes there were
accomplished studies on the welding behavior of low alloyed Romanian
steels, research on the under-pressure cracking corrosion behavior , and
development of certain welding and base materials resistant in hydrogen sulphide
environment. There were made systematic research on the cold, hot or
reheated cracking mechanisms, and the necessary experimental installation
was carried out.
technologies were elaborated for the components of chemical installations,
power plants, and off-shore drilling platforms. There were also developed
high productivity specific technologies through narrow gap welding,
submerged arc welding with one or more arcs, mechanized technologies for
hardfacing and reconditioning of various parts.
the field of constructive development of equipment for welding and
allied processes there were conceived and achieved a series of
devices for electric arc welding, resistance welding, special welding procedures, and installation and automatic machines for
gas, flame or plasma thermal
cutting. Within the modernization program for the
the field of material testing, new testing methods and devices were
developed for the study of mechanical behavior of steels for machine parts
and metallic constructions, researches were made for the assessment
of stress-strain state through electro-extensometry. Researches were also
made on the creep, fatigue, and brittle fracture of steels and
welded structures. There were also developed activities for the
elaboration of certain prediction methods on the durability and residual
life of components in metallic structures based on the concepts
of fracture mechanics and thermal fatigue.
1991, the activities on conceiving and producing welding equipment,
respectively on research and production of welding materials, are
continued within two independent institutions, S.C. TES S.A. Timişoara,
respectively S.C. TIMASUD S.A. Timişoara.
