What To Do If The Flange Is Welded Crooked?

During the process of welding flanges, the flange may be welded crooked due to various reasons. This not only affects the appearance, but also may affect the safe operation of the equipment. So, what can be used to pad the crooked flange? Here are some common methods.

Use special tools to pad

For crooked flanges, special flange correction tools can be used for padding. These tools are usually designed and made by experienced welders or engineers according to the actual situation of the flange. When using, just place the tool on the crooked part of the weld, and restore the flange to its normal position by applying appropriate pressure and adjusting the angle.

Use pads to pad

If there is no special flange correction tool, you can also use pads for padding. The pad can be made of metal or rubber, and the specific choice depends on the material of the flange and the working environment. Place the pad on the crooked part of the weld, and adjust the height and position of the pad to gradually restore the flange to normal. It should be noted that the thickness and size of the pad should be selected according to the actual situation of the flange to ensure the padding effect.

Adjust the welding method

In addition to using tools and pads, you can also prevent flange welding from being crooked by adjusting the welding method. Before welding, the position and angle of the flange should be carefully checked to ensure that they are in the correct state. At the same time, the appropriate welding process and parameters should be selected according to the material and size of the flange to ensure the welding quality. During the welding process, a stable welding speed and temperature should be maintained to avoid excessive deformation or stress.

Precautions

When performing flange gasketing, the following points should be noted:

First, it is necessary to ensure that the gasketing operation will not cause further damage or deformation to the flange. Therefore, the force and angle should be controlled during the operation to avoid excessive force or improper operation.

Second, after the gasketing is completed, the welding part should be carefully checked to ensure that the flange has completely returned to its normal position and there are no residual deformation or cracks.

Finally, if the flange is seriously distorted or cannot be rectified by simple methods, it is recommended to seek the help of professional welders or engineers to ensure that the problem is properly resolved.

Summary

In short, flange welding is not an unsolvable problem. Flange manufacturer should choose appropriate gasketing methods and pay attention to operation details. We can easily shim the distorted flange to ensure the normal operation and safe production of the equipment.
