Description of the welding process

WARNING! The arc starts at the moment when the welding electrode to the welding point touch and then will
be moved to a distance the length of the arc.

One specific example of welding by means of electrodes.

BASIC INFORMATION FOR 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 the larger

Workplace

Make sure the work area is clean.

earth wire

Clip the ground cable as close to the surface of the weld.

Electrode

Before the electric arc ignition, place the electrode in the torch. With the electrodes of smaller diameter
to be operated at less than the current to the electrodes with a larger diameter. Follow the data on the
welding current provided by the manufacturer.

Insulated welding gun.

The correct position of holding the torch.

The length of the arc.

The length of arc is the distance from the point of welding electrodes. In the case of a short arc of the
proper amperage and you hear sharp cracks. The appropriate length of the electric arc is similar to the
electrode diameter. Check the weld seam to determine if the arc is correct.

The length of the arc electrodes having a diameter of 1.6 mm and 2.4 mm should be greater than 1.6 mm, and the
electrodes 3mm and 4mm arc length should be greater than 3mm.

Slag

For removal of welding slag, use a hammer and brush. Remove slag and check weld bead before starting
a new weld.

surface. 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.

FEATURE ARC FORCE

ARC FORCE allows the arc. Shortening the length of the arc is accompanied by an increase in the welding current, which
results in stabilizing the arc. Reducing the value of the function gives a soft arc and a smaller depth of penetration, while
increasing the value of the function causes deeper penetration and the possibility of short-arc welding. At a set high value
ARC FORCE function you can be welded while maintaining the minimum arc length and a high melting rate of the electrode.

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.

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 the differences in the types of buffer zones to gain
knowledge select the right electrode for the job.

When choosing the electrodes need to consider:

1. Implementation example. Steel, mild steel and stainless steel.

2. The thickness of the welded material.

3. Position in which the weld is made.

3. Position in which the weld is made.

length is very important. Arc should have

a length of approximately 1.5 - 3 mm. Due to the burning of the electrodes must be kept adjust the length of the arc.

Most simpler method of controlling arc is relying on its own hearing. The correct length of the arc is characterized by a
crackling sound like frying eggs patelce. Invalid too long arc is revealed empty hissing sound or a sound like blowing.

d) Do stitches on a flat metal surface. Do them in parallel to the upper edge (the edge

furthest from you). This will give you practical skills in running straight welds, and also allow you to
easily track your progress. You will notice that the tenth weld will look much better than the first. By
constantly checking their mistakes and correct them, your progress in welding technology will keep the
increase. Through regular exercise after some time welding will be a matter of routine.

Base metals

Most metals found in farms and small shops are low carbon steel, sometimes offered mild steel. Typical items made
with this type of steel is the most common metal plates, pipes, rolling, angles, beams. This type of steel can usually
pospawać without special precautions. However, some types of steel contain large amounts of carbon. Such steels
are most commonly used in the connecting rods, knives and cutting grinding, axles, shafts, plowshares. Carbon steels
in most cases can be welded with success, however, caution should be exercised in maintaining proper temperatures
in the earlier welding and reheating the material to be welded. In some cases, you must carefully control the
temperature during the welding and the welding process. For comprehensive information on identifying and welding
different types of steel and other metals we purchase and read the detailed literature devoted to welding. Regardless
of the type of material to be welded, it is important to clean it of any dirt (rust, paint, oil, dust, etc.), Which significantly
affects the quality of the weld.
