Should a butt joint with unequal thickness use the thinner component? Is the short heat treatment holding time sufficient for thick plates?
When designing butt joints with unequal thicknesses, welding parameters, including the heat treatment holding time, are usually set based on the thinner component. However, for thicker sheets, the heat treatment holding time using only thinner elements may be insufficient, as thicker sheets require more time to achieve the same heat treatment effect. It is recommended to develop an appropriate heat treatment plan based on the specific thickness and material of the sheet. .
For post-weld heat treatment, the thickness is mainly determined by the thickness of the weld.
For post-weld heat treatment, the thickness is primarily determined by the thickness of the weld between the joined parts
This means determining the heat treatment thickness specifically for this joint. The heat treatment thickness for the butt joints of the thick plate itself is determined according to the thickness of the plate.
