Document Summary
Here, no melting of the materials takes place and no filler metal is used to make a joint: what is an electrical arc, refers to a discharge of electric current across a space in an electrical circuit. The electric: what does the term arc-on time mean, it refers to the proportion of total hours worked during which the electric arc is usually sustained in the welding processes. Also known as arc time: arc time= total time the electric arc is on/total hours worked, electrodes in arc welding are divided into two categories. Here, the heat is created at the junction by the electrical resistance to current flow. Application of the pressure is needed in this process to achieve the fusion of the materials. What is that disadvantage: is that this process is normally processed out in a vacuum to obtain a high quality weld.
