Robots fix beam deformation

Nov 24, 2013

Industrial robots and their workcells can be customized based on your specific needs. This was seen when Kawasaki Steel Corp developed a multi-axis robot to correct deformations of a wide-flange beam coming off the production line. This robot was able to help deformation that was caused by the original welding process.


A struc­tur­al ele­ment that has a length longer than width and thick­ness is deemed a beam. A slen­der ele­ment such as a beam can expe­ri­ence bend­ing and defor­ma­tion when it is sub­ject­ed to an exter­nal load applied per­pen­dic­u­lar­ly to the lon­gi­tu­di­nal axis. For exam­ple, a beam like a clos­et rod that sags under the weight of clothes is expe­ri­enc­ing bend­ing and deformation.

Kawasa­ki Steel Corp devel­oped a mul­ti-axis robot to cor­rect defor­ma­tions of a wide-flange beam com­ing off the pro­duc­tion line. This robot has a con­tact sen­sor, gas burn­er, and auto­mat­ic ignit­er use­ful for cor­rect­ing beam defor­ma­tions. In this case, the defor­ma­tion was caused by weld­ing and needs to be cor­rect­ed by heating.

Heat cor­rec­tion was pre­vi­ous­ly done man­u­al­ly, but the Kawasa­ki robot has changed the game. The robot’s con­tact sen­sor con­firms the posi­tion of the object while mea­sur­ing its defor­ma­tions. If there is a need for cor­rec­tion, the gas burn­er is ignit­ed to heat the deformed part. The final auto­mat­ic cor­rec­tion is made with high pre­ci­sion, one of the main ben­e­fits of using a robot.

The robot can cor­rect a wide-flange beam 500mm by 200mm by 10 mm by 16 mm with an accu­ra­cy of 0.5 mm.
