Explain why a few molecules of gas trapped inside microscopic pockets within the steel can cause porosity in GTA welding, but not in other types of welding.
What will be an ideal response?
During most other types of welding, fluxes on the filler metal capture these gas pockets and they are removed. However, because GTA filler metals do not have fluxes when these gas pockets become hot during welding, they expand and can sometimes cause weld porosity.

After you replace the servo drive card you find that they system will not run and is giving you alarms indicating that it is does not have information on the type of motor and encoder being used. What would be the likely corrective action to this problem?
You are working on a robot that has a servo drive alarm and find blown fuses on the drive. In the course of gathering information, you discover that the motor has a loose connection, which caused it to overheat, damaging the internal windings and the motor encoder. Once you replace the motor and encoder, you get another servo drive alarm that indicates there is a bad card in the drive.
