Construction machinery fuel tanks store fuel and hydraulic oil, and their welding quality directly determines operational safety and reliability. During manufacturing, welding parameters such as current, voltage and travel speed must be strictly controlled to avoid deformation or weld cracks caused by excessive heat input.
Post-weld airtightness testing is mandatory before delivery, usually by air pressure or kerosene leak tests, to ensure the weld is leak-free. At the same time, internal cleanliness must be controlled: weld spatter, oil stains and other contaminants entering the hydraulic system can cause clogged oil lines or component wear.
Ruizhide strictly follows welding process specifications and performs post-weld inspection and cleaning on every tank to ensure stable performance after installation on the host machine.
