It uses consumable electrode wire, which have a chemical composition similar to the parent material. This process is semi-automatic due to the automatic feeding of the filling wire electrode.
What is Arc Welding - Material Properties
Gas metal arc welding (GMAW), also known as metal inert gas or MIG welding, is an arc welding process in which the electrode is a consumable bare wire and shielding is accomplished by flooding the arc with a inert gas. Metal inert gas (MIG) welding, differs from the SMAW process in that its electrode is a bare solid wire that is continuously fed to the weld area and becomes the filler metal as it is consumed.What Welding Methods Require GasSome of the most common gases which are used as shielding gas are Argon, Helium, Carbon Dioxide, and Oxygen. Argon is a type of inert gas which means it will not interact with the workpiece. It is one of the most commonly used gases in TIG welding. Argon does not lead to oxygenation or change the chemical composition of the final weld.Welding process of 316L stainless steel pipe - YaangMay 05, 2018 · Argon arc welding, the nozzle 2 mm in diameter, extremely rich tungsten tungsten electrode, specifications 2.5 mm; 5. When the argon arc welding stainless steel, the back must be protected by argon gas to guarantee the back forming. The flow rate is 5-14l/min, and the positive argon flow rate is 1213l/min.
Welding of Nickel Alloys
Nickel alloys can be joined reliably by all types of welding processes or methods, with the exception of forge welding and oxyacetylene welding. The most widely employed processes for welding the non-age-hardenable (solid-solution-strengthened) wrought nickel alloys are gas-tungsten arc welding (GTAW), gas-metal arc welding (GMAW), and shielded metal arc welding (SMAW).Welding of Magnesium-base Alloys - Total MateriaElectrode wires or filler metals having composition conforming to ER AZ61A or ER AZ92A (Mg-Al-Zn) are considered satisfactory for welding alloys AZ10A, AZ31B, AZ31C, AZCOML, AZ61A, AZ80A, ZE10A and ZK21A to themselves or to each other. ER AZ61A is usually preferred for welding aluminum-containing wrought products because of tendency to resist crack sensitivity. The ER AZ92A filler metal shows less crack sensitivity for welding the cast magnesium-aluminum-zinc and magnesium-aluminum alloys.
