330107520 Left exhaust pipe welding assembly XCMG XDE130 Electric driving dump truck spare parts

The 330107520 left-side exhaust pipe welding assembly is an original XCMG product, specifically designed for XCMG excavators (such as XE60, XE200GH), loaders (such as LW321F, ZL50G), and road rollers (such as XS160, XD110). It addresses the pain points of ordinary welding assemblies, such as easy weld cracking, incomplete fusion, insufficient high-temperature resistance, and corrosion leakage. It is a core component for the installation and maintenance of equipment exhaust systems. The product uses high-quality base materials and is manufactured through CNC cutting, precision bending, TIG welding for the root pass + SMAW welding for the fill pass, weld flaw detection, and anti-corrosion passivation processes. It is suitable for high-temperature, high-dust, high-frequency vibration, and salt spray corrosion conditions, perfectly compatible with original equipment, and meets XCMG’s supply chain digitalization requirements.
