power requirements, vendor listing & registration, system
to improve productivity and retrofitting of existing welding systems
with semi-automatic and automatic equipments.
can be provided in rectification and repair of worn-out or cracked
components, assessment of the extent of damage & feasibility of
repair and recommendation of appropriate weld repair &
reclamation procedure. Services for surveillance during repair at
site and if necessary, the repair can also be carried out.
Procedure Specification (WPS)
critical pressure vessel and structural fabrications call for usage
of WPS as per applicable codes such as ASME, AWS, API etc. In this
connection WRI can assist in the development and qualification of
Life Assessment (RLA) of Power Plants and Process Industry
view of the prohibitively high cost of setting up new installations,
Residual Life Assessment for extending the operating period of aged
Power & Process plants has now become a mandatory requirement.
WRI has all the expertise to carry out Non Destructive and In-situ
metallographic examination and assess the extent of damage. After
detailed analysis, recommendations will be furnished to the customer
for further follow up actions like extended usage, replacement,
measurement and analysis of engineering components under
external and internal service loading conditions
stress analysis using Finite Element Method (FEM) by special
software like ANSYS
validation using hydro-test
and control of distortion through weld sequencing & other
methods involving jigs & fixtures for large scale structures
with number of sub-assemblies
stress measurement & analysis to arrive at the need for
stress relieving heat treatment
Integrity Analysis to assess the reliability & safety of
welded structures subjected to static and dynamic loading
design analysis & recommendation as per various
international codes like ASME, AWS and other piping codes.
and recommendation of applicable welding Codes & Standards.
Assistance to Industries
Establishment of welding fabrication
methods and jobbing services on a case to case basis are offered.
& Inspection Services
has full fledged mechanical, metallurgical, NDT and electronics
laboratories to carryout various types of tests conforming to
national and international standards.
Testing, Chemical Testing and NDT
WRI laboratory is well equipped to
carryout the following tests as per applicable sections of various
codes like ASTM,

Evaluation of New Materials
Institute houses a wide range of equipments to assess the
fabrication and material weldability aspects to enable defect free
welding. Determination of materials resistance to Hydrogen Induced
Cracking, Liquation & Hot cracking, Lamellar Tearing etc. and
optimization of welding parameters can be done. Facilities like
indigenously developed Implant Test Equipment, Elastic Restraint
Rig, Lamellar Test Rig, Thermal Cycle Simulator are available for
ascertaining the susceptibility of the material to cracking.
Weldability evaluation of Ferritic Stainless Steel (FSS) type 409 M grade (8mm and 3.15mm) was carried out for coal
bunker application. Base material tests like chemical analysis, tensile, bend and hardness were conducted. Weld
cracking sensitivity and weld joint tests were also carried out. The plates were found to be of weldable quality and
the mechanical test results of butt joints were found satisfactory.
