Welding after heat treatment
Thread Content
The equipment operates at atmospheric pressure and is highly hazardous. Overall heat treatment is now required, but due to structural reasons, the outer coil must be installed and the clamps welded after the overall heat treatment. Is it okay to use welding clamps after heat treatment?
First, it is necessary to understand the role of heat treatment. It is best to weld the reinforcement plates in advance and then attach clamps to them; this hardly affects the stress on the equipment. But be careful to consider whether the load-bearing capacity of this clamp has an impact on the stress on the equipment. For reference.
Most of the time, a statement can be seen on the diagram: Welding is not allowed on stressed components after heat treatment… Therefore, adding a shimming plate meets the requirements
