Arc welding Processes Group uses an electric arc to create heat to melt and join metals together.
A power supply creates a sustained electric arc between a consumable or non-consumable electrode and the base material to be welded, using either direct (DC) or alternating (AC) current. The welding is done by starting an arc, either by making contact of the electrode with the work and then separating the electrode to a proper distance to produce an arc.; or by using HF to strike it though the air gap. The arc can be either manually or mechanically guided along the line of the joint, while the electrode either simply carries the current or conducts the current and melts into the weld pool at the same time to supply filler metal to the joint. The processes in this group use the arc as a tool, like a tool on a lathe machine – different shapes and sizes to cut the metal.
This course is useful to understand various types of Arc Welding processes and to analytically know the apparent and hidden control parameters. The consistency of the welding quality depends on the Process Control as elaborated in ISO 9001-2015 – QMS document. Once known, the control of these process parameters can be rightly implemented in their actual production applications.
