Welded structural parts are important load-bearing and connecting components in construction machinery, widely used in frames, booms, dipper sticks and cover parts. Compared with castings, welded parts are lighter, more design-flexible and lower in cost, especially suitable for small-batch, multi-variety supporting needs.
Today, industry requirements have evolved from simple dimensional conformity to dimensional stability, weld quality and surface treatment consistency. Manufacturers are introducing CNC cutting, robotic welding and automatic painting to improve product consistency and delivery capability.
In the future, as host-machine manufacturers demand better traceability, welded structural part production will focus more on process standardization and full-process quality control.
