MAG Welding Robots

Met­al active gas weld­ing, also known as MAG weld­ing, is the most com­mon weld­ing method in the Unit­ed States, Europe, and Japan. The high pro­duc­tiv­i­ty offered by MAG weld­ing robots have con­tributed to its popularity.

The prin­ci­ple of met­al active gas weld­ing is that a metal­lic wire is fed through the weld­ing gun and melt­ed in an arc. The wire serves the dual pur­pose of act­ing as the cur­rent-car­ry­ing elec­trode and the weld met­al filler wire. Elec­tri­cal ener­gy is sup­plied by a weld­ing pow­er source.

A shield­ing gas that flows through the gas noz­zle pro­tects the arc and the pool of molten mate­r­i­al. The shield­ing gas is either inert (MIG weld­ing) or active (MAG weld­ing). In this con­text, an inert gas is one that does not react with the molten mate­r­i­al. Exam­ples of gas­es in this cat­e­go­ry are argon and heli­um. Active gas­es, on the oth­er hand, par­tic­i­pate in the process between the arc and the molten mate­r­i­al. Argon con­tain­ing a small pro­por­tion of car­bon diox­ide or oxy­gen is an exam­ple of an active gas.

MAG weld­ing requires the use of an active gas (i.e. car­bon diox­ide and oxy­gen). CO2 is a more com­mon­ly used short­en­ing of MAG weld­ing gas.

Met­al active gas weld­ing is the most com­mon­ly used arc-weld­ing tech­nique for sheet met­al weld­ing, main­ly of steel. The wire elec­trode serves both as filler mate­r­i­al and as arc elec­trode. The molten mate­r­i­al is pro­tect­ed from oxy­gen by chem­i­cal reac­tions between an active gas, like CO2, and addi­tives in the wire elec­trode. Typ­i­cal appli­ca­tions for MAG weld­ing include bicy­cle frames con­struc­tion and auto­mo­bile repair.

Both new and used MAG weld­ing robots are ben­e­fi­cial to com­pa­nies look­ing to improve their return on invest­ment (ROI) and enhanc­ing their weld­ing repeatability.

Robots​.com pro­vides new and refur­bished MAG weld­ing robots from Motoman, Fanuc, KUKA, and ABB. Recon­di­tioned robots are avail­able for low­er cost, some­times 50% less! All pre-owned robots go through an exten­sive recon­di­tion­ing and inspec­tion process.
