Remember to stick with the filler material placed directly in the nucleolus. The welding process is TIG welding method
in which the arc is maintained by the tungsten electrode (usually tungsten). Welding area (electrode, arc and weld
pool) is protected against contamination by an inert gas (eg. Argon), which constantly flows through the welding torch.

MIG
During welding, the torch moves the welding wire, which is constantly melting in an electric arc. The fluid material of
the welding wire connected to a combination of material to form a liquid weld pool. When moving the welding torch,
lake follow, to solidify at the edges and creating a durable combination of materials. Shielding gas is supplied through
the gas nozzle located on the torch. Gas protects the molten metal from the atmosphere, pollution and cooled welding
torch.
Fig. 2 Scheme MIG / MAG Fig. 2 Scheme MIG / MAG
Material should be completely cleaned of contaminants such as rust or paint. Any dirt have an impact on changing the
direction of welding and weld weakness. The area under the ground terminal must also be properly cleaned. To clean
is best to use an angle grinder with a sanding disc or a brush, or a steel brush.
The best results are obtained by holding the torch with both hands (you should then use a welding helmet), it affects
the use to control the position of the burner. Be aware of the welding position to have a good view on the weld and do
not breathe too gases produced during welding.
After the burner tip deviation from the vertical is achieved better visibility of the welding process. Contact tip should be
approximately 6 to 10 mm over a weld material. A good idea of how high the torch to keep the material will allow us to
trim the wire in the burner length 10mm
Among the many possible methods of carrying the torch frequently used zig-zag movements pushed, which are
aimed at keeping the bow in the direction of welded components. Method Front, which is pushing the burner is better
than the method from the rear (pulling burner) due to increased shielding gas coverage, and introduces joint on each
edge of the materials to be joined, resulting in a flat and neat seam. Exceptions are thin materials during welding,
which are two possible methods. Shall also conduct a simple burner without zigzag treats in this method required a lot
of experience. The easiest way to practice the arrangement of the weld in a single element. After a few seconds, weld
should decompose. If the puddle becomes too large welding is too slow or too high setting welding voltage; maybe
this

lead to burnout material welded. If the weld does not break down this welding dispenses too quickly and the seam is not
melted through the material.
Increasing the voltage increases the weld penetration (penetration depth) and elongation of the arc.
It is possible to weld with poor fitting the amperage, penetration may be too large or too small, but the welds remain
valid. By contrast, the mismatched wire feed speed, welding can not be obtained. The method for selecting a wire
feed speed experimentation. Wire feed speed adjustment is possible during welding, so the welding must be set in
the vicinity. Set the value of the current and the welding time to adjust the wire feed speed to achieve an optimal
effect.
Warning! Chamfering (grinding the edge of the materials to be welded in a V-shape) significantly reduces the
power required for welding of the material thickness. Grafting
The heat acting on the welded material interferes with its structure. When welding two pieces fitted together perfectly
after a few centimeters welds the gap between them starts to increase and further aesthetic weld location will be
impossible. The solution becomes spot welding. Between points vaccination in places unconnected continuous welds
should be placed. This will allow for good penetration, thereby solid connection.

Description of the method
FCAW - a method similar to MIG / MAG welding with the difference that instead of solid wire cored wire is used. The
wire is filled with welding powder producing protective gases is not, so the need to provide the shielding gas from the
cylinder.
A welding wire guard itself is the same as the MIG / MAG difference is the use of a wire which has a core is filled with
powder. Under heat generated during the welding of the core is molten and powder produced a gas atmosphere
surrounding the liquid pond. In the application of the wire itself casing can be dispensed with the gas supply from a
cylinder, which greatly influences the welding process.

BASIC INFORMATION FOR MMA WELDING
Otulinowymi welding electrodes (MMA) is a process in which metal is melted, and then combined, by heating it by
means of electric arc with consumable electrode coated metal wrapper flux. The electric current generates an electric
arc between the electrode and the material combined. During the welding electrode coating decomposes under heat
to form the gaseous substances which shield gas during the welding and slag.
If the electrode moves along a weld spot at the right speed deposited metal forms a layer called the seam.
Welding is powered by an AC source and can generate alternating current and constant. The best characteristics of the weld
obtained using a constant current.
In the circuit welding measured voltage and current. Voltage (V) is controlled by the arc length between the electrode
and welded surface and depends on the diameter of the electrode. It is a measure of the current in the welding circuit,
and is measured in amperes (A), is controlled by the dial. Setting the welding current is dependent on the diameter of
the electrode size and thickness of the welded material and the welding position. When welding materials with the
same thickness, materials with a small area is used lower electrode and a lower welding current than for larger
surfaces. Thin metal requires less power, and smaller electrode requires less power.

It is recommended that during welding work in the horizontal and vertical positions. However, while we are forced to
weld in vertical or overhead should set the current lower than the level during operation. The best welds are obtained
while maintaining a short arc, smooth movement of the electrode and the electrode leading down at a constant speed
during melting. More detailed welding procedures are presented in the following pages Supported.
WELDING ELECTRODES IN PRACTICE
No one can learn to weld by reading the instruction manual or other literature on the subject. The ability to correct
welding can be purchased only through practice. The information contained in the attached manual to help you
understand those rules inexperienced welding with coated electrodes and make it easier to start learning. For more
information about welding can reach for a comprehensive literature deeply about.
Knowledge welding operator must go beyond information about the arc. User welders must know how to control the
arc, which requires knowledge of the circuit and the welding device that provides current during welding. The welding
cable starts in the torch, wherein the electrode is mounted, and the end on the connector, wherein the cable is
attached to the welding machine. Current flows through the wire to the welding electrode holder and then by the
electric arc. On the other side of the working arc current flows through the wire to the base metal mass, then back to
the device. The system must be closed. Mass holder to be stably mounted on the metal base cleared. Metal must be
cleaned of paint, rust, etc. It is necessary to obtain a good current flow. Connect the ground cable as close as
possible to the welding point. Avoid closing the circuit through the welding hinges, bearings, electrical systems and
other such items that may impede the flow of current in the system. The electric arc is formed in a space between the
work piece and the welding electrode tip mounted on the torch. The molten metal moves along the arc for the
combination of materials, forming a weld bond.
Electrode Welding requires a strong grip and a welding tip, stable hands, good vision and good mental health. The
operator controls the welding arc welding and thus, the quality of the weld created.

They are designed for welding specialist welding masks and helmets protect the eyes during welding.
When working with an electric arc welder begins to "pull" handle, which is comparable to a stream of water from a
garden hose for use at the ground. The molten metal forms a lake or crater (small area of the molten metal surface) garden hose for use at the ground. The molten metal forms a lake or crater (small area of the molten metal surface)
which follow for the electric arc. During the movement of the electrode puddle is cooled and solidifies. Slag emitted
during welding protects the weld during welding.
Selection of a respective electrode
The function of the covered electrodes is not only the transfer of power to the electric arc. The electrode is
constructed of a metal core and a cover. The metal core is melted in an electric arc to fill the gap between the two
pieces of combined metal. Lagging also melts or burns in an electric arc playing the same important functions in the
welding process. During the melting of the electrode decompose chemical compounds contained in the electrode
coating to form gaseous products, which stabilizes the electric arc cloud protects the molten metal from oxidation and
pollution in the atmosphere. Other chemicals get together with the molten metal from the core of the electrode to the
weld pool to form a slag that forms on the weld layer protecting from further oxidation during cooling.
The differences for the different types of electrodes refer mainly to the type of the buffer zone. Changing the outer
coating significantly affects the characteristics of welding. by understanding
