Explanation: the rotor emf and current are zero at the speed of synchronous speed of the machine.
Explanation: k = 1/1.73 = 57.73%.
Explanation: due to inductor method, reactance increases and the starting torque decreases.
Explanation: for aluminum, the specific energy required is u = 2.9 j/mm3 therefore,
Explanation: electrodes for consumable arc- welding processes are classified according to the following properties:
Explanation: non consumable electrodes are the ones that are not consumed during the process of welding. gtaw (gas tungsten arc welding)/tig (tungsten inert gas welding), ahw (atomic hydrogen welding), caw (carbon arc welding) processes use non-consumable electrodes.
Explanation: furnace brazing is a semi- automatic used widely in industries and are best suited to large scale production operations.
Explanation: as the percentage of carbon in grey cast iron is less, therefore mig welding is preferable.
Explanation: separate flux/ shielding gas is not required in atomic hydrogen welding. the
Explanation: high current produces more heat. when we use a low voltage power source, it allows a welder to have some reasonable over the small lighting bolts we use to fuse metal together.
