### How does induction bending work?

Induction bending is a process used to bend pipes and tubes without the need for internal mandrels or other supporting devices. It involves the use of induction heating to heat a specific area of the pipe to a temperature where it becomes malleable and can be bent to the desired shape. .

#### Step 1: Pipe Preparation.

Before the bending process can begin, the pipe or tube must be prepared by removing any coating or insulation that may be present. This is to ensure that the induction heating can effectively heat the metal.

#### Step 2: Induction Heating.

Once the pipe is prepared, it is placed into an induction bending machine. The machine uses high-frequency induction coils to heat a specific area of the pipe to the desired temperature. The heat is applied evenly to create a uniform bend without causing any distortion or weakening of the metal.

#### Step 3: Bending Process.

As the pipe reaches the correct temperature, it becomes malleable and can be shaped into the desired bend radius using a set of forming dies. The bending process is usually controlled by a computerized system that ensures precision and accuracy in the final shape of the bend.

#### Step 4: Cooling.

After the pipe has been bent to the desired shape, it is quenched with a cooling medium to rapidly cool the metal and set the bend. This helps to maintain the shape of the bend and prevent any spring-back or deformation of the pipe.

#### Step 5: Inspection.

Once the bending process is complete, the pipe is inspected for any defects or irregularities. This ensures that the final product meets the required specifications and quality standards.

In conclusion, induction bending works by using induction heating to heat a specific area of a pipe to a temperature where it becomes malleable and can be bent to the desired shape. The process is precise, efficient, and produces high-quality bends without the need for internal support devices.
