Prevention and improvement of sheet deformation during welding

In the welding of thin plate large surface multiple welding points, often easy to produce welding deformation, affecting the later workpiece assembly accuracy and performance, welding a local heating of the material processing mode, welding deformation is the cause of the formation of all parts of the workpiece welding heat input is not uniform, thermal expansion and contraction inconsistency caused by welding deformation, and therefore the need to be prevented from deformation to prevent or improve the cause: 1, optimize process parameters, reduce the amount of heat input, such as increasing the peak laser, reduce the welding pulse width, without affecting the quality of the welded surface can effectively reduce the amount of welding deformation.

1, optimize process parameters, reduce heat input, such as increasing the laser peak, reduce the welding pulse width, without affecting the welding surface quality under the premise of welding deformation can be effectively reduced.

2, reduce the welding speed and flat rate, so that the heat input per unit of time into the workpiece is reduced, the welding deformation is reduced.

3, optimize the welding sequence, so that all parts of the workpiece heat uniformity, is also an effective way to reduce welding deformation.

Chaoqiang technical program

1. chaoqiang self-developed control system and chaoqiang wire feeder perfect combination of set power and speed with the reduction of thermal deformation effects per unit time.

2. Increase power, reduce speed can reach a welding balance value, to achieve the maximum optimization of process parameters to achieve the best welding effect.

3. chaoqiang independent research and development of the wire feeder can completely by itself through the wire feed speed to determine the welding speed, reducing the manual operation requirements, can be optimized through the process parameters to achieve the maximum solution to the problem of welding deformation, has been widely used in a variety of stainless steel 0.2mm above the welding process.
