Just
like any work of art, welding too requires a thorough knowledge of
the basics in order to master its different processes. Here is a
simplistic understanding about welding and related topics from Logos
Weld Products - one
of the leading Weldingrod manufacturing plants
in
India.
To begin with welding is the
process through which materials are joined together to form a firm
joint. Usually metals or thermoplastics are used in this process.
What makes welding different from the other metal joining techniques
like brazing and soldering, is the fact that when two metals are
joined together in this process, a decent amount of 'melting' of the
metals takes place.
Some of the best welding methods are:
- Shielded Metal Arc Welding
- Gas Metal Arc Welding
- Flux-Cored Arc Welding
- Submerged Arc Welding
Shielded metal arc welding uses
an electrode which has the flux around it. This flux is the
protectant for the puddle around the electrode. The electrode holder
on the other hand holds the electrode as it melts away in the welding
process. The slag on the other hand protects the weld puddle from
atmospheric contamination of any kind. Gas Metal Arc Welding on the
other hand uses a wire feeding gun. This wire feeding gun feeds the
wire at an adjustable speed and flows an inert gas (Argon gas) or a
mix of carbon dioxide and Argon over the weld puddle to protect it
from atmospheric contamination.
Flux-Cored Arc Welding is quite
similar to Gas metal arc welding. The only exception is that this
method of welding uses a special tubular wire filled with flux.
Depending on the filler, you can either use or not use the tubular
wire. While the Submerged Arc Welding makes use of an automatic fed
consumable electrode along with a blanket of granular fusible flux.
In this method of welding the molten weld and the arc zone are
constantly protected from the atmospheric contamination as it is
“submerged” under the flux blanket.
These
are some of the basic ways in which welding can be done.
