Q2. How many seams pipes are there?
Ans. 
Pipes can have various types of seams, primarily categorized into welded and seamless types.
• Welded pipes have seams created by welding two pipe ends together.

• Seamless pipes are manufactured without seams, providing higher strength.

• Common types of welded seams include longitudinal and spiral seams.

• Examples of welded pipes include ERW (Electric Resistance Welded) and SAW (Submerged Arc Welded) pipes.

Q4. How to measure pipe OD?
Ans. 
Measuring pipe OD involves using calipers or a tape measure to determine the outer diameter accurately.
• Use a caliper for precise measurement; place it around the pipe's outer edge.

• For larger pipes, a tape measure can be wrapped around the pipe and divided by π (approximately 3.14) to find the diameter.

• Ensure the pipe is clean and free of obstructions for an accurate reading.

• Take multiple measurements at different point

Q5. How much gap should be given in the pipe jointing TIG & ARC welding?
Ans. 
Proper gap in pipe jointing is crucial for effective TIG and ARC welding, ensuring strong and defect-free welds.
• For TIG welding, a gap of 1/16 inch (1.6 mm) is generally recommended for thin-walled pipes.

• For thicker pipes, a gap of 1/8 inch (3.2 mm) may be necessary to allow for proper penetration.

• In ARC welding, a gap of 1/16 to 1/8 inch is also common, depending on the pipe diameter and thickness.

• Example: For a 2-inc...read more

Q1. WHAT IS BLDC MOTOR
Ans. 
BLDC motor stands for Brushless DC motor, which is a type of electric motor that operates without the need for brushes to transfer electrical current.
• BLDC motors use electronic commutation instead of brushes to control the motor's operation.

• They are more efficient, reliable, and have a longer lifespan compared to brushed DC motors.

• BLDC motors are commonly used in applications such as electric vehicles, drones, and indu
