1/10/2019· Stick welding is a bit harder to master than MIG welding, but you can pick up a stick welding equipment for not much money. The electrode used for this method consists of a core wire that is coded influx and the electric arc is created when the tip of the electrode that is the work piece and is withdrawn while still remaining in close contact in order to generate temperatures of about 6500°F.

Welding - Infogalactic: the planetary knowledge core

During the 1920s, major advances were made in welding technology, including the introduction of automatic welding in 1920, in which electrode wire was fed continuously. Shielding gas became a subject receiving much attention, as scientists attempted to protect welds from the effects of oxygen and nitrogen in the atmosphere.

The core of this wire shields the weld puddle as it burns and does not require any gas. The benefit of welding without gas by using flux-core wire is that you can weld outdoors in windy conditions.

How to Prevent Porosity in Welding: 4 Simple Tips | …

Porosity in welding happens when a contaminant or gas is absorbed into the weld puddle. These impure welds are commonly referred to as cavities. Basically porosity in welding is a weak, bubble-filled weld that does not meet code and more importantly can in some cases, cause part of a project to become weak and collapse.
