Excavator

The welding production line for excavators is mainly used to manufacture core load-bearing structural components such as the boom, bucket arm, bucket, slewing platform, chassis frame, X-shaped frame, and counterweight housing. It is the most technically demanding and quality-controlled stage in the manufacturing of excavators.

Flexibility

Staff will make a production analysis of the customer’s future production needs and goals. Material flow analysis and planning define the optimal configuration and layout for your site.
Rhythmicization

Remote repair service enables instant visual connection to the machine despite its geographical location.
Intelligentization

Full range of spare and wear parts, including original spare parts, retrofit parts, and approved replacement OEM parts, all meeting the strictest quality criteria.

The excavator welding production line is mainly used for manufacturing core load-bearing structural components such as the boom, bucket arm, bucket, slewing platform, chassis frame, X-shaped frame, and counterweight housing. It is the part with the highest technical requirements and the most stringent quality control in the manufacturing process of excavators. The production line generally adopts an automated welding + flexible tooling + intelligent logistics mode, suitable for welding of high-strength wear-resistant steel and high-strength structural steel, and meeting the usage requirements of heavy loads, impact, and high fatigue life.

Overall Layout and Flow of the Production Line

The typical process flow is as follows

01 Raw Material Pretreatment
02 Part Cutting and Beveling
03 Alignment and Positioning
04 Robotic / Manual Welding
05 Post-Weld Slag Removal and Correction
06 Nondestructive Testing
07 Shot Blasting for Rust Removal
08 Proceed to Machining / Painting

Overview of the Automated Welding Workstation for Excavator Model X

The excavator X frame serves as the core load-bearing structure of the chassis, connecting the left and right track frames with the slewing base. All the walking loads and excavation impacts of the entire machine are borne and transmitted by it. The structure has complex forces and extremely high requirements for welding accuracy and strength. This automated welding workstation is specially designed for the X frame of the excavator, enabling precise assembly and fully automatic welding of components such as the main beam, cross beam, reinforcement plate, hinge seat, and connecting ear plate of the X frame. This effectively solves the problems of large deformation, uneven welds, and low efficiency in traditional manual welding, achieving intelligent and standardized production of the X frame welding process.

This workstation not only enhances production efficiency but also ensures the structural strength and overall stability of the vehicle frame from the very beginning, thereby extending the service life of the entire machine.

The production line adopts a streamlined layout. The equipment has a high degree of integration and strong automation. The core equipment consists of the following:

•The dedicated integral locking tooling provides stable positioning and effectively controls the overall twisting and lateral bending deformation of the X-frame.

• Equipped with a rotary table, it enables the workpiece to be rotated at multiple angles, allowing for full-position welding in flat, corner and vertical positions.

• Combined with real-time tracking of weld seams, it automatically corrects the welding trajectory, ensuring sufficient weld penetration and a full weld formation.

•Welding data is stored in real time, and process parameters are fully controllable, enabling monitoring of the production process and traceability of quality.

Overview of the Automated Welding Workstation for the Excavator Turntable

This automated welding workstation is specially developed for excavator turntables. It integrates precise fixture positioning, heavy-duty welding positioning equipment and multi-joint welding robots to achieve fully automatic welding of all primary and secondary weld seams such as the turntable base plate, upright plate, reinforcing ribs, bearing seat, and hinge ear seat.

1. Integrated Assembly and Welding Fixture

After the workpiece is precisely clamped and locked, the position changer can rotate and adjust at multiple angles, so that various ring welds, vertical welds and corner welds can be adjusted to the optimal horizontal welding position.
2. Improve production efficiency

The weld seams are well-formed and uniform, with a high qualification rate for flaw detection. This fully meets the standards for heavy-duty and wear-resistant, as well as fatigue-resistant usage of construction machinery.
3. Flexible Design

By quickly changing the fixtures, it is possible to adapt to the flexible production of multiple types of excavator turrets, and the welding process can be uniformly standardized.
4. Lean Control of Welding Cycle Time

The heavy-duty head-tail frame welding positioner, six-axis welding robot, intelligent welding power supply, dust purification system and integrated electrical control system are all components of this equipment.
