The main factors that need to be considered when designing Non-Standard Welding Parts include but are not limited to the following:
Material selection:
The performance of welding materials directly affects the quality and service life of welded parts. When designing, the welding performance, mechanical properties, corrosion resistance, etc. of the materials should be considered. Try to choose materials with good welding performance. If the material performance is poor, it needs to be treated accordingly as required.
Structural design:
The manufacturing rationality, economic rationality and safety of welded parts should be ensured during design.
Consider the convenience of operation during welding, arrange the welds reasonably, and reduce the number of adjustments of welding equipment and the number of flipping of workpieces.
The design should be conducive to reducing welding deformation, such as using intermittent welds, flat welding and horizontal welding.
Avoid designing welds in places where stress is easily concentrated to ensure the rigidity of welded parts.
Dimensions and tolerances:
The dimensions of welded parts should be accurate, including length, width, height, angle, etc. The tolerance range should meet the design requirements to ensure that production personnel can accurately process.
Welding symbols and markings:
Use standard welding symbols to mark welding methods, welding positions, weld forms, etc. to guide welding operations.
The markings should be clear and easy to read, and avoid using vague or ambiguous expressions.
Economic rationality:
When designing, consider how to save raw materials, such as making the shapes of the sheets used as standardized as possible to reduce the scrap generated during cutting.
Try to match the sizes of each part so that some sheets can be manufactured by nesting and cutting to reduce waste.
Reduce the workload of welding, such as reducing the number of blanks for welding and replacing several thin plates with one thick plate.
Inspection and evaluation:
When designing, consider the inspection methods and evaluation standards of welds to ensure that the quality of welded parts meets the design requirements.
Safety:
Consider the safety of welded parts in use, such as avoiding excessive concentration of welds, preventing cracks and reducing deformation.
In summary, the design of Non-Standard Welding Parts needs to comprehensively consider multiple factors such as materials, structure, size, welding symbols, economy and safety to ensure the quality, performance and safety of welded parts.
