Aluminum Welding with Fanuc robots

Aug 24, 2013

Fanuc robots has industry leading robots in a variety of applications, including aluminum welding. Aluminum welding is becoming widely popular in automotive and other industries and they are using Fanuc robots for the job. Aluminum welding is more challenging, so it is important for the operator to understand the process. ​


Alu­minum weld­ing is a process that is becom­ing more and more com­mon in the auto­mo­tive and oth­er indus­tries as com­pa­nies are opt­ing for alu­minum over steel con­struc­tion. Many of these man­u­fac­tur­ers turn to Fanuc Robot­ics and their line of alu­minum welders to han­dle this task.

Alu­minum weld­ing is more dif­fi­cult aes­thet­i­cal­ly than steel weld­ing because it is not as for­giv­ing. It is impor­tant that the man­u­fac­tur­er and the robot oper­a­tor under­stands the process of weld­ing alu­minum and how to con­trol it so that any pit­falls may be side­stepped before they start.

When using Fanuc for alu­minum weld­ing, man­u­fac­tur­ers can turn to the ARC Mate series of robots. The Fanuc arti­cle states that these robots can do the work of ten welders with out­stand­ing cos­met­ic and qual­i­ty standards.

For Fanuc, the alu­minum weld­ing process is broke down into sec­tions: start­ing with the arc, weld for­ma­tion, weld depo­si­tion, arc end­ing and burn back. Once a robot­ic alu­minum weld­ing sys­tem gets through start­ing the arc, the hard­est part of alu­minum weld­ing is over.

From there, it is a mat­ter of decid­ing which weld­ing tech­nique will be used for the alu­minum work piece. There are three dif­fer­ent tech­niques, includ­ing run-in, ramp­ing and direct entry. Run-in is the most com­mon tech­nique for alu­minum weld­ing. How­ev­er, if man­u­fac­tur­ers do not want to use run-in, they can use ramp­ing for thick­er mate­ri­als and direct entry for thin­ner materials.

If the man­u­fac­tur­er is using a Fanuc alu­minum welder, the qual­i­ty of the weld will be increased because of the weld sta­bi­liza­tion process and weld depo­si­tion will be high­er. Then the weld is end­ed and the weld wire is sep­a­rat­ed from the weld pud­dle dur­ing burn back.

With Fanuc Robot­ics, alu­minum weld­ing is just a mat­ter of fol­low­ing the steps and prop­er programming.
