Iranian Firm Exports Nano-Coated Welding Electrodes to EU
"Currently, we exported our products to the neighboring countries, including Georgia, in the past few years and we succeeded in entering the European Union markets,” said Mohammad Reza Afkhami, the chairman of the Board of Directors of Dorsan Sim Sanat Yazd company.
“A few months ago, we sent 24 tons of electrodes to Spain, and at present, there is a lot of demand both in the domestic and foreign markets,” he added.
“Instead of copper coating, we used other compounds in nanometer dimensions. By substituting these nanomaterials instead of copper, there is no need for a tub and acidic compounds, and the risk of acid evaporation in the environment is zero,” Afkhami said.
“With this new technology, we have managed to increase efficiency by 50% with the same amount of manpower and electricity consumption, and we have 50% more production,” he stated.
In a relevant development in August, nanotechnology experts at an Iranian company managed to make a new type of welding electrode which is resistant to moisture.
‘AMA Industrial Co’ company has manufactured the moisture-resistant alkaline welding electrode whose coating is included by oxide nanoparticles.
The new coating prevents the hydrogen absorption on the electrode surface and avoids the hydrogen cracking in humid media.
The incorporation of nanoparticle into the shielding coatings of welding electrodes has resulted in making the electrode moisture-resistant, reducing the hydrogen absorption on the electrode surfaces, and preventing the hydrogen cracking in the parts welded in humid media.
The nano-based electrode can be used for welding in humid media and welding of metallic parts which are prone to hydrogen cracking.
