Automotive MaintenanceWelding Electrode
Hydrogen cracking is considered as a defect in welding which often happens in heat affected zone (HAZ) and can severely affect the quality of welded zone, resulting in irrecoverable damages. Hence it is vital to prevent such defects. One of the Hydrogen cracking reasons is entering moisture to the weld metal through electrode coating. Therefore production of moisture resistant welding electrodes and satisfying AWS A5.1 standard test is the main goal of electrode manufacturers. Using nanotechnology and especially nanoparticles in production of welding electrode coating is one of the solutions to this challenge.
