| titleOfInvention | Method of manufacturing welded hollow bodies |
| abstract | The method of manufacturing welded hollow bodies, in which the steel strip is shaped by molding, while being lubricated into the shape of welded hollow bodies, the hollow bodies are welded, tested for tightness, cleaned and phosphated. A cleaning agent concentrate containing 10 to 20 wt. % citric acid, 10 to 20 wt. % phosphoric acid monoester, 0.5 to 5 wt. % of a nonionic surfactant and / or a cationic surfactant or 0.5 to 2.5 wt. amphoteric surfactant, and which is diluted with water to a concentration of 0.5 to 3% for use. A thin layer phosphating solution is used on the iron and the pH value is continuously recorded in the phosphating bath and the pH value is deviated from the predetermined set point value by the deviation of the pH value. 0.2, the pH is adjusted to a predetermined setpoint, and phosphate layers of less than 1 µm are applied. |
