Automobile body welding production line is one of the important production lines in the production process of cars, minibuses and other models. From the perspective of the development history of the automobile industry, the body welding line has experienced manual welding lines in the 1950s and 1960s to automated rigid welding in the 1970s. Assembly line - the stage of robotic flexible welding assembly line after the 1980s.

Development Trend of Automobile Welding Production Line

At present, the development trend of the world's automobiles is from mass production to multi-variety and small-batch production. In order to meet the extensive and diverse needs of automobile consumers and adapt to the fierce competition in the automobile market, major automobile manufacturers in the world continue to shorten the model change Cycle, to speed up the update of vehicle types, so the modern automobile welding line is gradually becoming more flexible in function.

In a narrow sense, the flexible production line generally refers to the mixed production of various models. Various models can adjust the proportion of the entire model arbitrarily according to changes in market demand and under the premise that the total output remains unchanged. Various flexible transmission devices such as elliptical ground circular lines and elevated upper and lower circular lines (as shown in Figure 9) have appeared successively. For example: the T100S/FINR ASSYLINE of Daewoo Motor Corporation of South Korea is to produce the car bodies of three different models of T-100, 3-door, 4-door and 5-door, in mixed flow on the same transmission line.
