Welding Use Meaning. Though welding is widely used most of us are not very well-versed with the graphical representation of this process. This technique was discovered during efforts to manipulate iron into useful shapes.
Understanding polarity is essential as it can impact everything from the welding machine setup to the type of electrode being used. The weld projects through the top surface and just like with the spot weld it melts through into the material of the joint beneath it to form a solid joint using a high heat input. The electric arc is created between the tip of the consumable wire that is constantly fed to the electrode and the weld pool on the base metal.

The weld projects through the top surface and just like with the spot weld it melts through into the material of the joint beneath it to form a solid joint using a high heat input. You can hear people call them gas MIG welders because of that are the most common shielding gases in welding but other gases can be used. The feed wire is continually melted and becomes part of the weld pool. It is a type of fusion welding process which uses an electric arc for supplying necessary heat to join the base metals and the filler metals.
