submerged arc welding wire |
 |
|
Submerged arc welding wire is mostly used for welding of carbon steel and other alloy steel metal that has comparatively low strength. The welding materials are composed with welding wire and flux composite. In the submerged arc welding operation, the composite and property of the welding seams depends on both the welding wire and the flux.
When choosing submerged arc welding wire, the customers should not only consider the effects of flux composition, but also take into account the impact of base metal composition. To achieve the ideal property, one kind of flux (flux melting) and several types of welding wire can be used together. Or, one kind of welding wire with several types of flux complexes. It should be noted that the mechanical properties of the all-weld metal test specimens used for the classification of a wire/flux combination will vary from those obtained in production due to differences in welding procedures such as wire size and welding parameters.

mig welding wire |
|
|
Mig welding wire can be aluminum welding wire, stainless steel welding wire or other alloy wire specially for mig welding processes.
Solid wire MIG welding:
Metal inert gas (MIG) welding was first patented in the USA in 1949 for welding aluminium. The arc and weld pool formed using a bare wire electrode was protected by helium gas, readily available at that time. From about 1952 the process became popular in the UK for welding aluminium using argon as the shielding gas, and for carbon steels using CO 2 . CO 2 and argon-CO 2 mixtures are known as metal active gas (MAG) processes. MIG is an attractive alternative to MMA, offering high deposition rates and high productivity.
Process characteristics
MIG is similar to MMA in that heat for welding is produced by forming an arc between a metal electrode and the workpiece; the electrode melts to form the weld bead. The main differences are that the metal electrode is a small diameter wire fed from a spool and an externally supplied shielding gas is necessary. As the wire is continuously fed, the process is often referred to as semi-automatic welding.
Shielding gas
In addition to general shielding of the arc and the weld pool, the shielding gas performs a number of important functions:
forms the arc plasma
stabilises the arc roots on the material surface
ensures smooth transfer of molten droplets from the wire to the weld pool
Thus, the shielding gas will have a substantial effect on the stability of the arc and metal transfer and the behaviour of the weld pool, in particular, its penetration. General purpose shielding gases for MIG welding are mixtures of argon, oxygen and CO 2 , and special gas mixtures may contain helium. The gases which are normally used for the various materials are:
