METHODS OF WELDING

Gas welding 311 – usually when acetylene is burned at temperatures up to 3100 ° C, it is used for welding sheets with a thickness of 0.4 mm to 40 mm.
Gas welding involves fusing the edges of the combined metals with a heat source in the form of a gas flame (acetylene-oxygen). The weld is formed from melted edges of the combined material and an additional binder (metal rod) fused in the flame. Welding is carried out by means of a burner, whose task is to reduce the combustible gas and oxygen ratio and burn them in a suitable ratio

Electric welding 111 – Arc welding with a coated electrode is also called MMA (Manual Arc Welding) and it is the oldest and most universal arc welding method.
The MMA method uses a coated electrode, which consists of a metal core covered with a compressed jacket. An electric arc is produced between the end of the electrode and the material being welded. The arc ignition is contact by touching the end of the electrode to the welded material. The electrode melts and drops of molten metal electrodes are transferred through an arc to the liquid weld pool of the metal forming a weld after cooling. The welder feeds the electrode as it fuses to the work piece to maintain a constant length arc and at the same time moves its melting end along the welding line. The melting electrode casing releases gases that protect liquid metal from the atmosphere and then solidify and forms on the surface of the lake slag, which protects the solidifying weld metal against environmental influences. After removing the electrode from the workpiece, the electric arc stops and the welding process is interrupted. After laying one stitch, the slag must be removed mechanically.

The TIG 141 method – consists in generating an electric arc by means of a non-burning tungsten electrode in an inert gas shield. The welding arc between the non-weldable electrode and the welded material melts the surface of the material. It is not necessary to use additional material in TIG welding. The welded elements can be joined by melting the welding groove. However, if additional material is used, it is introduced into the pool in a manual manner and not by means of a welding torch as in the MIG / MAG method. Therefore, in TIG welding, the welding torch has a completely different design than the handle used in the MIG / MAG method. The binder is usually available in the form of a wire (rod) with a length of 1 m and a properly selected diameter.

The TIG welding process takes place surrounded by a chemically inert protective gas, usually argon or helium, flowing out of the nozzle of the electrode holder. The shielding gas protects the weld and electrode against oxidation, but has no effect on the metallurgical process.
titanium, nickel and their alloys.

Method 135/136, otherwise known as MAG (MIG), is a solid or powder welding method. In this welding method, practically two types of shielding gases are used. Active gas, from which the name of the MAG method is derived, i.e. Metal Activ Gas, and an inert gas (noble) from which the name MIG, i.e. Metal Inert Gas, comes from.
In the active gas method, the most commonly used gas is carbon dioxide CO2 with the addition of argon Ar. In the ratio of 82/12%. This method is welded to steel with normal use.
In the second method, which is mentioned above, or MIG, an inert gas such as Argon (Ar) or Hel (H) is used. However, most often Argon is used. The method is welded with stainless steel or aluminum. However, usually this method is used to weld slightly thicker components.
