Large-scale frame welding machining is currently a relatively large number of welding machining parts. In the process of large-scale frame welding machining, we should not only know the welding technology preparation for large-scale frame welding machining and the technical requirements of large-scale frame welding machining, we should also know How to choose the tooling and fixture for welding machining of large frame.
Tooling and fixtures play a very important role in machining. Choosing a suitable tooling and fixture for welding of large-scale frames can improve machining efficiency and the quality of machining workpieces.
So how to choose the tooling and fixture for welding machining of large frame?
- 1. Ensure that the weldment can obtain the correct geometric shape and size after welding.
- 2. Safe and reliable when used.
- 3. It is convenient for welders to operate and use.
- 4. Easy to manufacture, easy to maintain, and low cost.
- 5. The workpiece should be clamped firmly on the fixture, especially when screw clamping is used, the clamping force should be appropriate to prevent shrinkage cracks when the weld is cooled.
- 6. It is not allowed to correct and correct the workpiece on the fixture to prevent the deformation of the fixture and affect the assembly accuracy of the weldment.
- 7. When several clamps are used on a weld at the same time, the pressure of each clamp should be kept consistent.
Choosing the right tooling fixture can make the welding process of the large frame more safe and reliable, and can better improve the machining efficiency and the quality of the machined workpiece.
