We at DEIPL undertake exhaustive quality assurance tests to ensure that only the best products carry the FAIRWELD brand. Our philosophy is to quantify quality, make it measurable, maintain reproducibility, reduce deviation and enhance the process capability. We have incorporated industry standards and innovative quality control tests in tandem with our production process so that the problems surface right away for immediate correction and prevention.
An all weld fillet test is conducted to check for the running welding performance & appearance of the weld bead by trained and certified welders.
An all weld test specimen is machined and tested to check for the yield strength, ultimate tensile strength and elongation at rupture.
The thickness of copper coating is measured by wet dissolution method using liquor ammonia. The uniformity is observed under 100x magnification.
The charpy strength of the weld metal deposited is tested at desired temperatures to check the strength conformity at shock loads.
Wire samples are stored in a highly corrosive controlled environment to check the corrosion resistance of the wire.
The amount of hydrogen dissolved in the weld metal must be below required levels so that welds do not crack on cooling. A 72 hour test is conducted for its measurement.
Gamma Ray and X Ray Radiography of weld specimens are conducted by external agencies certified by the Bhabha Atomic Research Center.
Cast, Helix and dimensional measurements are carried our to ensure superior wire feedablity.
