Fundamentals of electrode welding
Electrode welding is one of the most common welding processes and is usually the first welding technique that prospective welders encounter during their training. Also known as manual arc welding, stick electrode welding or electric arc welding, the process provides the basics for understanding how welding equipment works and how electrical voltage interacts with the metals being processed.
Arc welding with stick electrodes has several advantages over the more complex MIG/MAG or TIG welding techniques. It can be used flexibly, is independent of additional shielding gases and allows any type of weld seam to be made. In addition, electrode welding can be carried out in almost all weather conditions and in difficult overhead or forced positions with almost all materials. Accordingly, this welding technique is used everywhere in the metal trades and industry, with a focus on steel and pipeline construction.
This is how hand electrode welding works
In electrode welding, the arc is generated by contact between the workpiece and the stick electrode. The electrode and workpiece form two electrical poles between which a short circuit occurs for a short period of time. The current flow feeds the arc, which generates the desired heat of fusion between the workpiece and the electrode. In the process, the core wire together with the electrode coating successively melts away and provides its own protective gas bell.
The amperage is decisive in electrode welding
Manual arc welding is performed with low voltage but high amperage. For this purpose, the welding device must transform the connected mains voltage into a low welding voltage and provide the necessary amperage, which at the same time serves to regulate the current source. To ensure that the joint quality of the welding work meets expectations, the current source must always provide as constant a current intensity as possible. This also applies if the arc length should change during the work. Therefore, current sources for electrode welding technology have a sloping characteristic curve.
