This is similar to how shielding gas protects.

How to arc weld metal for beginners. However it does have its own disadvantages as well. If you attempt to arc weld without a flux covered welding. Starting the arc welder stick is actually easy.

To guarantee a stronger weld bevel the edges of your work pieces. Arc welding or stick welding as its referred uses a flux covered rod to weld with. You then turn the machine on and move the positive lead torch gun or electrode to the location that you want to weld.

Practice steadying the arc by holding the electrode about 18 to 316 of an inch from the work piece then begin moving along the path you want to weld. Stick Welding Shielded Metal Arc Welding or SMAW considered to be the most commonly used method in America but more challenging welding method for beginners The first method is a process in which a wire electrode is continuously fed through a flexible tube and out of the nozzle of a welding gun into the welding pool joining the base metals together. One needs to strike it the same way as a match and lift it slightly and the rod will start burning on its own.

The electricity of the welder will pass through the rod and the arc and will create a temperature of up to 7000 F at the point of contact. The electric arc is made between the work and the tip end of a small metal wire - the electrode - which is clamped in a holder. As you move along the joint welding electricity builds heat to form a weld puddle of molten metal.

Prepare the metal pieces youll join. Because the metal is hot it is easier to control. The electric current that goes through the electrode melts it so that a weld pool is formed on the workpiece.

Typically the arc gap should be no greater than the electrode diameter. When the positive lead makes contact with or gets close to the metal that has been grounded a welding spark will occur. It is a fast process.

This arc-welding circuit has a voltage output of up to 79 volts which is enough to shock. As you move the electrode the metal will be melting away filling the pool of molten metal and building your weld. The heat generated from this arc of electricity is what melts the metal and allows you to weld.

Tap starting and scratch starting are the two common methods of starting the arc. Learn to run a straight bead. Filler metal is introduced at the point of the weld to help form the weld.

Arc welding is the process of joining 2 metals together using an electrode as the filler rod and an electric arc to melt the metal. CAREFULLY REVIEW THE ARC WELDING SAFETY PRECAUTIONS AT THE BEGINNING. Flux is a chemical coating thats used when welding to protect the liquid weld puddle from atmospheric gases like nitrogen and oxygen.

The welding surface should be free of any contamination including paint. ELECTRIC SHOCK CAN KILL. This allows the metal to move easily in the arc thus giving better quality welds.

Bare metal welds best. Welders perform stick welding by creating an electric arc between the workpiece and metal electrode. The electrode has a flux coating which melts down to safeguard the weld pool from corrosion and contamination from the environment.

The holder is held by the welder. TIG welding is a method of welding where the metal is heated to very high temperatures which cause the metal to become fused. The arc is started by touching the electrode momentarily against the work to complete the electrical circuit before raising the electrode to establish the arc.
