The main welded parts of construction machinery components include the frame, bucket, arm, etc.

1、 Frame

The frame is an important load-bearing component of construction machinery, mainly completed through welding. The quality and strength of the frame directly affect the working ability and service life of the vehicle. The frame is welded from multiple components, and welding defects such as cracks and deformations can seriously affect the service life of the frame and the safety of the entire construction machinery. Therefore, the manufacturing of the frame requires high-quality welding processes and precise welding equipment to ensure the quality and safety of the product.

2、 Bucket

The bucket is an important component of construction machinery such as excavators and loaders, which needs to withstand a large amount of impact and wear. Therefore, the manufacturing of buckets requires high-strength and high-quality welding to ensure their reliability and lifespan during operation. The bottom plate, protective plate, and auxiliary tooth plate of the bucket often need to be strengthened, requiring high-quality welding technology and quality control.

3、 Arm

Arm is a part of construction machinery such as excavators and cranes that is equipped with arm components, and its quality and strength directly affect the working ability and safety of construction machinery. Therefore, the arm needs to undergo high-quality and high-density welding processes to ensure its quality and reliability. During welding, it is necessary to strictly control the processes of material pre heating, tissue relaxation, etc., to avoid cracks and deformation, and ensure the high strength and long service life of the product.

In summary, the frame, bucket, arm, etc. are important parts of construction machinery welding, requiring high-quality and efficient welding processes and strict quality control to ensure product quality and reliability.
