For many people who are new to hand welding or irregular hand welding, it is not easy to have good welds and quality assurance. Here are five basic things you need to consider when performing manual arc welding to ensure weld quality: Set current, arc length, arc welding angle, welding electrodes and welding speed. Preparation […]
The energy of the arc (heat and light) is concentrated and is used to melt the metal when soldered. Arc is a strong and continuous discharge in the gas between the opposing electrodes. In order for the discharge to occur, the gas must conduct electricity (containing charged particles such as ion, free electrons). The condition […]
Arc welding requires that an electric arc be established between an electrode and the workpiece to produce the heat needed for melting the base plate. Motor- or engine-driven welding generators are wound to deliver the correct voltage and current directly; therefore, no transformer is necessary. A wide range of small devices and assemblies made from thin […]
Flux-cored arc welding (FCAW) Flux-cored arc welding is a welding procedure of forming an electric arc between an automatically fed, hollow wire filled with flux and work piece. While the arc heat melts the parent metal, filler wire and flux, the flux may also add extensive material or elements and breaks down in the arc […]
