NAVTTC Workshop Worker Computer Test SVP + Practical Test Complete Guide TIP 2026 #navttc #workshop – Transcript

00:00So, today's video is about the workshop workers NPT and computer test, and also the practical. What questions come up in it? I've discussed it in complete detail in this video, and God willing, in the next video, the tool that comes up in the computer test, I will, God willing, discuss it with you, so kindly, if you're new and haven't subscribed to the channel, please do so.

00:21So let's start our video. So we have question number 1 first. In question number 1, it's asking what is the main purpose of the Lodo system in a workshop. We have option A, saving electricity, option B we have, increasing machine speed, and after that we have option C, preventing accidents, option D is reducing noise.

00:40So in this, option C will be correct, which is that we use the Lodo system to prevent accidents. Next we have question number 2, that during mig welding, if the wire sticks to the tip instead of burning continuously, then what setting could be the problem?

01:00In this, option A we have is wire speed, option B is workpiece thickness, and option C is weld position, and option D is colotype. So in this, option A is correct, that when there is a problem with the wire speed, then it sticks to it, it will stick to the tip.

01:19Okay, so this way we have question 2, and after that we have question number 3. In question number 3 we have, if a label applied with a label marker comes off quickly, what is the problem? Option A is the surface is not clean, option B is marker failure, option C is label size, option D is label size.

01:41So option A is correct, if the surface isn't clean, the label will come off. Question number 4, a glass cutter makes a line, but the glass doesn't break cleanly. What's the usual cause?

01:57Option A is low pressure, option B is wrong angle, option C is thick glass, option D is a crooked line. The answer here is option A, low pressure. What happens with low pressure?

02:12It just makes a line on top. Next, we have question number 5. Question number 5, if a punch and die set tears at the whole edges, what does this indicate? Option A, too much clearance, option B, too little clearance, option C, correct alignment, option D, correct press.

02:32So option A is correct, there's too much clearance. Next, we have question number 6. What's the effect on the next reading if a torque wrench isn't reset? Option A is less accuracy.

02:49Option B is more incorrect torque. Option C is less power, option D is noise. So, option B is correct, it affects the next reading with incorrect torque. Next, question number 7.

03:10What does it mean if stress cracks appear on forged hot dies? Option A is correct heat, option B is overheating, option C is less time, and option D is correct forging.

03:26So, option B is correct, cracks appear when it's too hot. Next, we have question number 8. In a hydraulic press, if the pressure is in uniform, where's the usual fault?

03:41Option A is in the cylinder, option B is in the oil line, option C is in the frame, option D is in the die. In a hydraulic press, if the Jackson doesn't get pressure, the oil line is faulty, so it doesn't apply equal pressure on it.

03:58Next, we have question number 9. In a drill press, what is the common reason for a hole not being oval? Option A is the workpiece is hard, option B is the drill bit is bent, option C is the speed is low, option D is too much pressure.

04:20So, option B is correct, the drill bit is bent, which is why the hole is in circular. Next, we have question number 10. After sandblasting, if different places on the surface look different, what does this indicate?

04:38Option A is uneven pressure, option B is correct grit, option C is cleaning, option D is less time. So, option A is correct.

04:54When there's uneven pressure, not equal on all surfaces, then you'll see a difference in those places. Next, we have question number 11. If an angle grinder is on but the disc isn't spinning, where could the problem be?

05:12Option A is the switch, option B is the disc cover, option C is the disc cover, option D is the handle. If the angle grinder is on but the disc isn't spinning, it means there's an issue with the switch. Jiggle the switch and the angle grinder should work.

05:29Number 12. Why is there dark glass in a welding helmet? Option A, for heat, option B, to increase light, option C, to increase light, option D, for eye protection. So, option D is correct. We use dark glass, black glass, for eye protection.

05:47Next, we have question number 13. In 13, we have, why is a guard necessary on an angle grinder? The cutting machine, it has a guard for protection. Option A, to decrease or increase speed.

06:05Option B, to stop sparks. Option C, to save the motor. Option D, to save the motor. So, option B is correct. The guard stops sparks from hitting your face, protects your body, your eyes. Next.

06:22We have question number 5. What color is the earth wire usually? Option A is red. Option B, blue, option C, green, option D, black. So, the earth wire is green. Next, we have question number 15.

06:40For what type of fire is CO2 effective in a fire extinguisher? There are three to four types of fire extinguishers. So, what is CO2 used for? Option A, wood, option B, paper, option C, electrical fire, option D, cloth. So, option C, for electrical fires, a CO2 cylinder is used in the fire extinguisher.

07:03Next, we have question number 16. Question number 16 says, what must be checked before using power tools? Option A is color. Option B is its weight. Option C we have wire and plug, option D we have brand.

07:21So option C, its wire and plug are checked. Power tools include equipment, etc., and things like cutting machinery, welding machines, etc. These come under power tools. Next, we have question number 17.

07:37If the dial indicator needle returns to its position without jerking, what does it indicate? It indicates, option of the shaft is straight, option B the shaft is straight, option D the bearing is bad, option D we have motor failure. So, option A is correct here.

07:54When the shaft is straight, the dial indicator needle will return straight to its original position without jerking. Option, we have question number 18. If the blade bends to one side during a cut in a bandsaw, what is the first thing to check?

08:13Blade tension, motor power, workpiece size, or coolant lab. So, in this, we have option B, that blade tension is checked. Next, we have question number 19. If the machine vibrates excessively while making a cut in a chopsaw, what could be the initial reason?

08:32So, option A we have, the disc is loose, option B is, the table is high, option C we have, the angle is not correct, the angle is correct, and option D is there is no motor. So, option A is correct here, that when the disc is loose, the machine will vibrate more.

08:49Next, we have question number 20. What is the biggest cause of slip hazard in our workshop? Option A, oil or water, option C we have noise, option D we have heat, so, in this case, options A and B are both correct, that oil and water can cause your foot to slip, that falls under slip hazard.
