Introduction,l cutting. Welding is the non-detachable joining or coating of components or base materials under the (mostly local) application of heat or pressure, with or without the use of filler material (definition according to German Standard DIN 1910 ). Joining is preferably performed with the welding我不死扛 发表于 2025-3-24 03:20:14
Welding temperature fields,ne is produced at the welding spot (fusion welding). With the combined action of pressure producing local plastic deformations, heating to just below the melting temperature is also sufficient (pressure welding). Only in exceptional cases is welding performed solely under local pressure (cold weldin流利圆滑 发表于 2025-3-24 09:51:56

Reduction of welding residual stresses and distortion,n. Triaxial tensile residual stresses in combination with cracklike defects promote brittle fracture. Uniaxial or biaxial tensile residual stresses diminish corrosion resistance and enhance the stability limit; compressive residual stresses improve the fatigue strength. Details of this are providedPigeon 发表于 2025-3-24 18:09:56

Welding temperature fields,se metal and filler metal fuse, metallurgical processes proceed in the weld pool, regions of the metal solidify and recrystallize, and microstructural transformations take place during heating and cooling. The temperature field, therefore, determines the welding residual stresses not only directly tInterlocking 发表于 2025-3-24 23:43:08
