Driven by increasingly stringent environmental regulations and the booming new energy vehicle industry, the manufacturing process innovation of exhaust purifiers, as core components for controlling automobile exhaust emissions, is becoming the focus of the industry. Ultrasonic welding machines, with their unique non-contact welding advantages, are reshaping the production model of exhaust purifiers. They not only solve the pain points of traditional welding technology, but also open up a new path for efficient, environmentally friendly and intelligent manufacturing. Exhaust purifiers are composed of multiple precision components such as metal carriers, catalytic coatings, and shells. The welding quality directly affects the sealing, durability and catalytic efficiency.

Traditional resistance welding or laser welding has problems such as large heat-affected zone, high risk of deformation, and coating damage, while ultrasonic welding machines achieve solid-state welding through high-frequency vibration friction, which perfectly avoids these defects. However, unstable power supply voltage may cause a series of problems with ultrasonic welding machines. First, unstable voltage will cause abnormal vibrations when the welding head is working, which will affect the welding quality, such as cold welding or leaking welding. Secondly, voltage fluctuations may damage the internal electronic components of the equipment, especially the control circuit boards that have strict power supply requirements. In an environment with unstable voltage for a long time, the overall life of the equipment will be significantly shortened, increasing the company's maintenance costs and production risks, and affecting production progress and product quality. This article will analyze in detail the equipment abnormalities caused by unstable power supply voltage of Bishan ultrasonic welding machine, and provide effective solutions.

Abnormal performance of the equipment caused by unstable power supply voltage of the ultrasonic welding machine: Decreased welding quality: Unstable voltage will cause fluctuations in the output power of the ultrasonic generator, which in turn affects the stability of the welding amplitude, resulting in problems such as loose welding points and insufficient welding strength.

Frequent equipment alarms: The built-in protection system of the ultrasonic welding machine will monitor the power supply voltage. When the voltage exceeds the safe range, the equipment will automatically alarm and shut down, affecting production efficiency.

Damage to core components: Long-term voltage fluctuations may damage key components such as power modules and transducers, increasing maintenance costs.

Welding parameter loss of control: Voltage fluctuations may cause parameter drift in the equipment control system, making it impossible to perform welding tasks according to preset parameters.
