Welding is
one of the most efficient and economical ways to affix metals together. The
process doesn’t merely join two pieces as in soldering and brazing but, with
the usage of excessive heat, also causes the metal structures to become
entirely one. Tandem Torch Welding and other welding techniques are among the crucial aspects of industrial
processes. They require more variables and sciences as compared to those
included in other industrial processes.
Widely used welding techniques
There are
two major types of welding process – Pressure welding and fusion welding.
Pressure
welding is a specialized technique and finds its use in only a handful of
industries. Fusion welding processes include arc welding, pipe bevelling, gas welding and gas metal arc welding. All these
methods are widely used in many industries.
In arc
welding, a metal welding rod is melted to form the welded joint. Pipe bevelling is involves the
formation of an angle at the end of the pipe’s edge and a plane perpendicular
to the surface.
Gas pipe to pipe welding procedure involves
heating two pieces of metals locally, hence surpassing their melting point so that
they become one together. The gas metal arc welding process uses a metal
welding rod, which undergoes melting to create the welded joint. The process
also uses an active or inert gas to produce a barrier between the atmosphere
and the weld, to enhance the strength and quality of the joint.
Advantages of Welding
- A joint created efficiently through the process of tandem torch welding or other welding processes is usually as strong as the base metal
- Welding is faster and more economical solution as compared to other processes like casting or bolting
- A large number of alloys and metals, both either similar or dissimilar can easily be affixed with welding
- General welding equipment isn’t very expensive and the portable equipment is easily accessible
To sum up,
welding process requires dealing with high level of gases, electric current and
temperature. Therefore, it is crucial to undertake safety measures while
welding. Looking out for quality welding machines from renowned manufacturers
could decrease the margin of errors significantly.
