Moisture-Resistant Welding Electrode Produced by Iranian Company
‘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.
Earlier this year, a technological company in Iran had also succeeded in replacing copper with nanomaterials in making welding electrodes to decrease environmental hazards.
“By using these nanomaterials instead of copper, there is no need for an acidic bath and compounds, therefore, the risk of acid evaporation in the environment will be zero,” said Mohammad Reza Afkhami, the chairman of the board of directors of the company.
“Also, in common electrodes, a lot of water is needed, and with this replacement, water consumption has reduced,” he added.
Noting that the company’s experts have made lots of efforts to replace copper with different materials to decrease costs and minimize the negative environmental impacts, Afkhami said, “We have succeeded in increasing efficiency by 50% with this new technology.”
"We have also managed to enter the European markets in the past few years and exported 24 tons of electrodes to Spain. We are currently exporting our products to neighboring countries including Georgia," he concluded.
