1. Preparation work before welding
Before welding structural components, preparations need to be made. Firstly, determine the welding sequence, and secondly, assemble the components to be welded. After assembly, it is necessary to clean the joints to ensure welding quality.
2. Welding sequence
When welding, it is necessary to follow the following sequence:
(1) Firstly, weld from the periphery inward, and then weld from top to bottom. This can ensure that the component will not deform due to temperature changes during welding.
(2) For circular structural components, the two ends of the diameter should be welded first, then the middle part should be welded, and finally the joint should be filled.
(3) For T-shaped structural components, the horizontal part of the T-shaped structure should be welded first, and then the vertical part should be welded. This can avoid deformation of components caused by welding.
(4) For I-type structural components, welding should be carried out from the center to both ends, and then the joint in the central part should be filled.
(5) For trapezoidal structural components, parallel sides should be welded first, and then beveled edges should be welded.
3. Precautions
When welding structural components, the following precautions need to be followed:
1. The welding sequence needs to be adjusted according to different types of structural components.
2. It is necessary to monitor the welding process and promptly address any deformation caused by temperature changes.
3. Strict temperature control is required during the welding process to ensure welding quality.
For the welding of large structural components, multiple welding machines are required to ensure uniform heating and welding.
The welding sequence of structural components has a significant impact on welding quality and efficiency. When welding, it is necessary to adjust according to different types of structural components and strictly control the welding temperature. Under the appropriate welding sequence, better welding effects and quality can be achieved.
