Calibration is one of the many ways to achieve a precision in leak testing. Internal calibration delivers the desired results for the most leak testing applications since the leak detector properly tunes to helium and correctly reports the leak it sees. However, accuracy is influenced by numerous factors, most of which are not in control of the leak detector and…
Marine industry and its offshore platforms including both fixed and mobile consider safety as its number one priority. One of the biggest safety issues on board is that the living quarter demands a positive pressure while the operation and especially during an emergency situation. If we see the average common safety rule, it clearly states that leak testing must be…
The utilization of the lasers for welding has proved its worth since the last 35 years in the selected applications. In spite of being high in the capital cost, the precise, highly intense heat source makes the laser as a perfect choice around the tight tolerances, close fit-ups, and thin materials. Lasers produce less distortion comparatively, on a few applications…
Laser marking is nothing different than burning the leaves with a magnifying glass. We burn the leaves with magnifying glass simply by placing a lens over the leaf at the focal point of the lens; here the lens collects the sunlight. The collected sunlight then focuses on the leaf and concentrate the sunlight on the small spot of the leaf.…
Dual axis, which is also called as dual-plane models, makes the measurements from the two different angles or viewpoints. The two measurement axes are perpendicular and coplanar to each other. The product that is to be measured is placed perpendicularly to the measurement field. To measure the diameter, ovality, and position of the product micrometer is typically used. Considering the…
A torque testing system is specifically the range of capacity id from utilized as a device for the quality control test or to calibrate the torque controlled tools. This comprises of electronic torque wrenches, click torque wrenches, and dial torque wrenches, electric screwdrivers, pulse tools and many more. The Torque Testing involves measuring the amount of torque that is being…
Helium is one of the best-suited choices to find the leaks because it is non-toxic, inert, non-condensable, non-flammable and is present in the atmosphere in the trace amounts (5 ppm). Since the atomic size of the helium is small it easily passes through the leaks. Hydrogen is the only molecule smaller than helium. Hydrogen is not used in leak detection…
