Difference between mechanised, automated and robotic welding


Frequently Asked Questions

The definitions of each term according to the British Standard BS 499:Part 1: 1991 are as follows:

Mechanised welding - Welding in which the welding parameters are controlled mechanically or electronically and may be manually varied during welding to maintain the required welding position.

Automatic welding - Welding in which all of the welding parameters are controlled. Manual adjustments may be made between welding operations but not during welding.

Robotic welding - Automatic welding using a robot that can be pre-programmed to different welding paths and fabrication geometries.

Successful application of mechanised/automated systems can offer a number of advantages. These include increased productivity, consistent weld quality, predictable welding production rates, reduced variable welding costs and lower part costs. Limitations include higher capital investment than for manual welding equipment, a need for more accurate part location and orientation, and more sophisticated arc movement and control devices. As such, production requirements must be large enough to justify the costs of equipment and installation, the maintenance of equipment and the training of operators/programmers for automated/robot equipment.
