Daoke Dao Laser Welding for Automotive Battery Coolant Pipe Fittings: Corrosion-Resistant & Airtight

Date：2026-01-19 13:58 Source：daokedao Browse：7

Automotive battery coolant pipe fittings face corrosion from coolants and require airtight welding to prevent leakage. Traditional welding has poor chemical resistance, leading to coolant seepage and battery damage. Daoke Dao plastic laser welding equipment ensures durable pipe connections. Suitable for PP and PEX materials, the welds match the base material’s corrosion resistance, withstanding ethylene glycol-based coolants. The continuous weld seam achieves IP67 protection, blocking coolant leakage and air intrusion. The 3D welding path adapts to the complex layout of battery cooling systems. Compliant with automotive thermal management standards, the equipment operates stably in production lines with a welding speed of 2m/min. It has passed 5000-hour corrosion tests, ensuring long-term reliability. The automated process reduces manual errors, improving batch consistency. Daoke Dao supports new energy vehicle manufacturers. Contact us for coolant resistance data.
