Peculiarities of manual arc welding with a portioned weld formation are considered. Advantages of this method compared with continuous arc welding include widening of the capabilities of controlling the weld and HAZ metal structure and improvement of mechanical properties and technological strength of welded joints.
Keywords: arc welding, covered electrodes, pulsed-arc welding, portioned weld formation, portioned heat input, pilot arc, structure, hardness
