<a href="https://www.dashweld.com/electric-welding-machine/">Electric Welding
Machine</a> refers to machines apparatus, and jigs and fixtures required for the
fabrication of welded articles from semifinished stock. A welding position, or
station, is a set of welding equipment for operations that require some degree of
participation by a welder. A welding line combines several welding stations.
</p>
<p>
Welding stations may be used in arc welding, resistance welding, gas welding,
electron-beam welding, or other methods. The welding equipment includes the <a
href="https://www.dashweld.com/electric-welding-machine/arc-stick-welding-
machine/">ARC Stick Welding Machine</a>, power supplies, and devices directly used to
conduct the welding process, jigs and fixtures for the rapid assembly of the parts to
be welded, for holding the parts during welding, and for preventing or reducing
warpage of the welded articles, auxiliary equipment used for transporting the parts
during welding and for mounting and transporting the welding apparatus, and various
other tools used by the welder. Various transport means and instruments for
controlling weld quality are also used in the welding process. The technical
characteristics of welding equipment are determined by the welding method chosen, the
type of production, and the degree of mechanization, that is, whether manual,
semiautomatic, or automatic welding is performed.

A welding station is a section of a production area where a power supply,
current-carrying conductors, and necessary jigs, fixtures, and welder’s tools are
located. In order to protect personnel in the area from radiation, the welding
station is enclosed by curtains or panels. Fixed automated stations are widely used
in modern manufacturing processes; such stations are located in manufacturing shops.
Mobile stations are used in the field for welding large objects in construction and
repair work.

Welding stations include power supplies and equipment for the regulation of the
arc during welding. Power supplies used in welding should provide a convenient,
continuous or step control and must satisfy general requirements for electric
machines and equipment. <a href="https://www.dashweld.com/electric-welding-
machine/ac-dc-tig-welding-machine/">AC DC TIG Welding Machine</a>, transformers,
generators, and rectifiers are used in electric welding; gas generators are used in
gas welding. Power supplies may be single-position or multiposition types, stationary
installations for continuous, long-term operation, or small, portable units for work
of short duration.

A welding transformer is used to match the parameters of the welding circuit and
the power supply; it also functions as a voltage regulator. In <a
href="https://www.dashweld.com/stud-welding-machine/">Stud Welding Machine</a>, the
voltage is regulated mechanically or electrically. In the former case, the distance
between the primary and secondary windings is altered. Electrical regulation is
accomplished by changing the control currents in supplementary windings, located on
the upper and middle field frames of the transformer. In this method, the secondary
winding is divided into two sections, one of which is located in the upper window of
the transformer. Such a transformer is capable of producing various no-load voltages
without a change in the turn ratio; this property is required for welding
adjustments. Welding transformers used in resistance welding have a minimum short-
circuit resistance and a secondary winding that usually consists of one or two turns.
Changes in secondary voltage are achieved by tapping sections of the turns of the
primary winding.

<a href="https://www.dashweld.com/air-plasma-cutting-machine/">Air Plasma
Cutting Machine</a>s are becoming an increasingly common tool in many industries such
as metal fabrication, construction and automotive repair. This tool is able to cut
through several types of metal including steel, copper, brass and aluminium by
generating an extremely high-temperature, electrical channel of ionised gas otherwise
known as plasma.
</p>
<p>
To create the 4th matter – the plasma – the cutter sends an electric arc
through a gas, (either oxygen, nitrogen or argon) which rapidly increases the heat
levels to the point where it goes beyond a solid, liquid or gas and becomes plasma.
The machine will then use the plasma to transfer the energy to any conductive metal,
allowing it to cut through with very little or no resistance. This method results in
a clean, fast cutting process.

<a href="https://www.dashweld.com/laser-welding-machine/">Laser Welding
Machine</a> or laser beam welding is one of the most widely known, accurate types of
welding processes. It is a non-contact, high power density welding process used to
join multiple pieces of material together using energy emanating from a laser beam.
Aerospace, defense and military, medical, electronics, petrochemical refining,
communications and energy are some of the common areas where laser welding techniques
are applied extensively.

Deep weld penetration and minimized heat inputs are the special
characteristics that set laser welded products apart from other conventional welding
processes;
</p>
</li>
<li>
<p>
Pulsed or continuous laser beams are used depending upon the welding
application;
</p>
</li>

<p>
There are many types of laser welding available and the most popular
types include Nd:YAG laser welding, CO2 laser welding, and diode pumped laser
welding;

Deep narrow welds, without any distortion, and minimal heat-affected
zones can be obtained using our laser welding machines that can function at increased
travel speeds.
