Welding is the
process of melting and fusing two metals with the use of excessive heat. To
fuse both the metals, there needs to be a filler metal called consumable. These
filler metals or consumables are what help form the joint.
The consumables can
be termed as wires, electrodes, plate or pipe depending on their form.
Consumables of the finest quality should be bought from trusted welding
consumables manufacturers. The parent metals, the consumables, heat
source, shielding together facilitate the process of welding.
Types of Consumables
Welding
consumables suppliers have the following types of consumables to fulfill
the unique requirements of welders.
Stick Electrodes
Stick electrodes
are also known as welding rods. Welders dealing with stick electrodes need to
have high welding skills. If you go by the American Welding Society, E6010,
E6011, E6012. E6013, E7014, E7024 and E7018 are the types of stick electrodes.
To select the right
stick electrode, you need to discuss the ideal flux composition as well as
diameter with your welding
consumables suppliers in India. The desired outcomes can be produced
with the right choice of electrode.
Fluxes
Oxidation is a
common issue while welding. Flux from welding
consumables manufacturers in India serves as an effective protection
against oxidation of hot metals. It works by forming a shield of gas around the
pool. The burning of flex leads to chemical reactions which in turn produces a
gas that acts as a protective layer against exposure to atmospheric impurities.
The flux leaves
behind a slag to obstruct porosity. When used with alternating current, flux
contributes to the stability of the arc. Flux with high levels of iron content
are beneficial for increasing the deposition rates. Flux containing deoxidizers
are beneficial when the surface of base metals is contaminated with rust or
corrosion.
SAW Wires
This type of
consumable is used together with flux for best results. For more information on
how the flux and wire may react with the base metals, you may have to discuss
your requirements in detail with welding
consumables suppliers. These wires are characterized by remarkable
mechanical properties, provided they are subjected to heat after welding. Here
is a quick tip: select a wire and flux that matches the strength of the base
material.
Flux Cored
Wires
Gas and
self-shielded are the two types of flux cored wires. Slag removal is easy in
case of gas-shielded flux-cored wires. Gas shielded flux cored wires are more
compatible with thicker metals. The flux coating hardens quicker than the
melted weld which is helpful in overhead and vertical welding positions.
The spatter levels
are low in self shielded wires and aid in side wall fusion. These wires aren’t
included in the final product. Choose welding
consumables manufacturers that have been in the industry since long for top
grade products.
