Abstract

The invention discloses a device and a method for controlling welding stress and deformation by combining heating with welding and chilling. The device comprises a supporting system as well as an automatic travelling device, a welding system, a heating system and a cooling system which are connected with the supporting system. A welding seam high-temperature region is cooled, and near weld zones at the two sides are heated, so that dynamic multi-stretching effect is generated; requirements on constraints of a clamp are avoided, and welding is carried out under a non-constraint condition, so that control on welding residual stress and deformation is realized to carry out welding under a non-support condition, and relatively great space volume is not occupied.

Description

technical field [0001] The invention belongs to the technical field of welding, and more specifically relates to a device for controlling welding stress and deformation along with welding heating and chilling. At the same time, the invention also relates to a method for controlling welding stress and deformation with welding heating and chilling. Background technique [0002] Aluminum alloys are widely used in aerospace, shipbuilding, civil engineering and rail transportation due to their excellent properties such as low density and high strength. However, aluminum alloy structures often have defects such as pores, undercuts, and cracks during the welding process, especially for thin-walled structures, where welding deformation is particularly obvious. Welding deformation not only brings considerable difficulty to the assembly of the structure, but also greatly reduces the bearing capacity of the structure, and also affects the overall appearance of the product. The weldin...
