Material Testing Facilities:
Qualitative and Quantitative analysis of materials by Alloy Analyzer is based on "Spark Emission Technique" that can analyze FE, Cu, Al, Ni and Co base alloys. C, Ni, Zn can be detected up to 0.002%. Other elements like Si, S, P, Cr, Al, V & As can be detected up to 0.001%.
Ferrite Content Measurement Equipment:
It is important to test the ferrite content of the stainless steel either in welds or surfaceing/cladding, since ferrite influences the properties of a weld in many ways. Electronic magnetic induction principle is utilized to measure the relative permeability of material in an alternating magnetic field of the equipment's probe to determine the ferrite content.
PWI provides complete range of mechanical testing services. Test specimens are prepared for metallic and non-metallic materials for the evaluation of tensile, compressing, impact, weldability, fatigue and bend preperties.
100 Ton Computer controlled Universal Testing Machine that can perform tensile, compression, bending, shearing & hardness tests of metallic and non metallic materials within load accuracy of +1%. Elevated temperature tensile tests can be carried out by attaching heating furnace (heating upto 600 Degree) with the standard machine. Test are conducted as per ASTM, BS, DIN, GB or client specified standards.
NDE Test Samples with Known Flaws
The flawed specimens that PWI creates for National NDE industry are specifically designed with precise flaw placement in a wide variety of specimen geometries and alloy types. Our flawed specimens are used in various industries to facilitate the education, practice NDE training, personnel qualification, procedure qualification and procedure demonstratioin in accordance with ASME, API and other codes, specifications and standrads.
Testing/Calibration of Welding Equipment
The quality and consistency of a weld depends on the welder, the materials and the welding equipment. Variability in the output of the welding equipment will affect the quality of the weld. In arc welding processes the quality of weld depends upon accurate and repeatable setting of parameters such as current, voltage, speed, gas flow, pulse characteristics etc. The adoption of mechanized welding, the introduction of quality assurance programs and the increased understanding of the factors which control weld quality have led to the demand for more rigorous calibration and validation of equipment performance.
PWI is fully equip to provide the all possible services to the industry for welding equipment testing and calibration.
