As an important part of door and window sealing materials, EPDM strips need to be welded in order to achieve a good sealing effect and strengthen the connection. Welding securely joins two or more EPDM strips together, providing a durable seal. This article will introduce the welding method of EPDM strips in detail.

1. Hot air welding: Hot air welding is a commonly used welding method for EPDM strips. It uses a heat gun to blow hot air against the welded joints, causing the surfaces of the joints to melt and bond together. This method is suitable for welding thicker EPDM strips and can achieve stronger connection strength.
2. High-frequency welding: High-frequency welding is a welding method that uses high-frequency current to generate heat at the joints to melt and bond the joints together. It is suitable for thinner EPDM strips, which can achieve high welding speed and precise welding control.
3. Ultrasonic welding: Ultrasonic welding is a welding method that uses ultrasonic vibration to generate frictional heat on the joints, melt the joints and form a firm connection. It is suitable for thinner EPDM strips, and has the characteristics of fast welding speed and high welding strength.
