What is the type of welding defect is caused due to stresses on heating and cooling called?
Your Answer : (Not Answered)
Correct Answer : B
Slag entrapment (inclusions) welding defect is caused due to stresses on heating and cooling.
In abrasive jet machining, as the distance between the nozzle tip and the work surface increases, the material removal rate
Your Answer : (Not Answered)
Correct Answer : D
The material removal rate is first increases because of area of jet increase than becomes stable and then decreases due to decrease in jet velocity.
Calculate the weld per minute, work speed of circular electrode of 220 mm diameter for carrying out seam welding at 4 welds per cm on 1.6 mm thick mild steel tube. Welding cycle consists of 3 cycles ‘on’ and 2 cycles ‘off’ Power supply is at 50 Hz.
Your Answer : (Not Answered)
Correct Answer : B
Weld per min = (frequency × 60)/ (cycles for weld + interval cycles)
= (50 × 60)/ (3 + 2) = 600 welds/ min.
Work speed (mm / min) = (welds/ min) / weld required per mm
= 600 / (4/10) = 1500 mm/min.
