Abstract

The invention discloses a device and method capable of reducing butt welding line angular deformation, and relates to a welding device and method. The device is characterized in that the two ends of a hinge shaft are hinged to lateral supports respectively, two compression rods are arranged on a front plate and a rear plate respectively, the upper ends of hydraulic cylinders are fixedly connected with the compression rods, the lower ends of the hydraulic cylinders are hinged to connecting pins, the lower end of a lead screw is connected with a stepping motor, a lifting transmission plate is connected with the lead screw in a threaded mode, the two sides of the lifting transmission plate are respectively hinged to a top plate supporting rod, the upper end of one of the top plate supporting rods is hinged to the front plate, the upper end of the other one of the top plate supporting rods is hinged to the rear plate, a top plate angle sensor is arranged below a hinge type reversible deformation top plate, a plurality of gas outlet holes are formed in the pipe wall of a hinge pipe, and the hinge pipe is communicated with a protection gas bottle through a gas guide pipe. The method includes the steps of (1) setting the numerical value of an offset angle alpha, (2) presetting an offset angle alpha between the front plate and the rear plate, (3) installing and clamping the two to-be-welded plates, and (4) carrying out butt welding on the to-be-welded plates with the preset offset angle alpha. The device and method are used for the plate butt joint.

Description

technical field [0001] The invention relates to a welding device and method, in particular to a device and method capable of reducing the corner deformation of a butt weld. Background technique [0002] Welding is widely used in various industries, but there is no good device and method to avoid the deformation of products after welding. Welding deformation can lead to a large reduction and deviation of product dimensional accuracy, performance degradation, scrapping or failure. Welding deformation mainly occurs in three stages: the first stage occurs when the welding is in progress, at this time the plates are clamped and fixed by the clamp and then welded and connected, welding stress and thermal expansion are the main deformations in this stage; the second stage is from the completion of welding At this time, the weldment enters the cooling process from high temperature to normal temperature. The release of welding stress during cold shrinkage is the cause of deformation ...
