When the dust removal box plate machine is assembled under welding stress, if the constraint of the welded parts is small, such as thin plate thickness or in a free and unconstrained state, the welded parts will undergo corresponding dimensional changes, shortening, bending or warping. When the tile press machine is assembled under welding stress, if the constraint of the welded parts is small, such as thin plate thickness or in a free and unconstrained state, the welded parts will undergo corresponding dimensional changes, shortening, bending or warping.

If the constraint degree of the welded component is high, such as a thick plate, complex shape, or being in a strong constraint state due to human imposed fixtures, the welded component cannot deform freely, but local strain will be generated under welding stress, and significant residual stress will be generated. The peak residual stress in the weld zone can reach the yield strength value of the material.

Therefore, the magnitude of internal stresses in welding is related to the thermal expansion coefficient of the steel and the degree of joint constraint. The expansion coefficient of structural steel changes very little, while the degree of constraint is related to various factors such as the form of structural nodes, welding sequence, plate thickness, and the degree of fastening of external fixtures.
