THE INNOVATIVE SOLUTION FOR DIFFUSIBLE HYDROGEN CONTENT DETERMINATION IN METALLIC COMPONENTS
HELIOS 3-FASTENERS is an innovative solution to get fast, precise and repeatable measurement of diffusible hydrogen content in metallic samples.
HELIOS 3-FASTENERS can be used:
- to measure diffusible hydrogen content in electroplating components (bolts, fasteners, springs, etc.) foundries, castings, metal manufacturing, welding and fabrication process samples;
- as laboratory instrument for R&D applications.
Once acquired, the signal is processed by proper mathematical codes (by means of a dedicated panel PC), in order to return the diffusible hydrogen content.
HELIOS 3 FASTENERS can be used to estimate the level of diffusible hydrogen that can cause a reduction in mechanical properties of a metallic component. The estimated value can be used to evaluate the suitability of supplied batches of fasteners or to optimize processes such as dehydrogenation duration. It can also be used to assess the effects of corrosion caused by the environment. HELIOS 3 FASTENERS aims to prevent delayed component fracture through quality control of galvanized batches.
HELIOS 3 FASTENERS can be also used to estimate the diffusible hydrogen concentration adsorbed by the galvanized components of brake line terminals and connectors. The furnace temperature can be set to 180°C. Incorrect galvanization of brake line terminals can cause hydrogen leakage into the brake fluid, leading to an extended brake lever travel, decreased braking capacity, and increased risk of accidents.
Letomec can provide a customized solution based on the dimensions of the customer's samples.
The HELIOS Platform including HELIOS 3-FASTENERS is coverd by the Patent N. EP 2912452 B1.

THE INNOVATIVE SOLUTION FOR DIFFUSIBLE HYDROGEN CONTENT DETERMINATION IN WELDING SAMPLES
HELIOS 3-WELDING is an innovative solution to get fast, precise and repeatable measurement of diffusible hydrogen content in welding samples.
The most common technique for the diffusible hydrogen measurement is described by the standard ISO 3690:2012. The techniques specified in ISO 3690:2011 include collection of diffusible hydrogen via displacement of mercury or collection into a headspace filled with an inert gas such as argon. The amount of hydrogen collected is determined by measuring the displaced volume in the former and by, for example, thermal conductivity in the latter.
The temperature for collection of diffusible hydrogen is controlled to avoid thermal activation of non-diffusible hydrogen.
Moreover the measurement requires inert gas and chemical substances restricted by the current REACH norm. HELIOS III Welding overcomes these limits and it is able to perform test substituting mercury by heating the sample using a furnace.
Once acquired, the signal is processed by proper mathematical codes (by means of a dedicated panel PC), in order to return the diffusible hydrogen content.
Letomec offers a customized solution in function of customer sample dimensions.
