Abstract

Arc welding is a type of welding that uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The process of arc welding is widely used because of its low capital and running costs. In this paper, arc welding parameters are determined for shielded metal arc welding method. Parameters are selected depending on welding methods and in the present study some parameters are included and some of them are excluded. To determine the welding parameters, the national and international welding standards and also welding experience are taken into consideration for shielded metal arc welding method. In the present study, the determined welding parameters are examined in detailed for shielded metal arc welding method and the resultant ideal welding parameters and their limits are given in equations and tables.

Key words: Shielded metal, arc welding, electric arc, welding parameters,optimization.
