Automation of arc welding

Arc welding is a type of welding process using an electric arc to create heat to melt and join metals. A power supply creates an electric arc between a consumable or non-consumable electrode and the base material using either direct DC or alternating AC currents. Arc welding is a fusion welding process used to join metals. The arc can be either manually or mechanically guided along the line of the join, while the electrode either simply carries the current or conducts the current and melts into the weld pool at the same time to supply filler metal to the join. Because the metals react chemically to oxygen and nitrogen in the air when heated to high temperatures by the arc, a protective shielding gas or slag is used to minimise the contact of the molten metal with the air. Once cooled, the molten metals solidify to form a metallurgical bond.

Cables with damaged insulation or exposed bare conductors shall be replaced. Joining lengths of work and electrode cables shall be done by the use of connecting means specifically intended for the purpose. The connecting means shall have insulation adequate for the service conditions. By Standard Number Part Number:. Arc welding and cutting.

The output of the machine is designed in a way that it can be varied by adjusting the crank of the machines in clockwise or anti-clockwise direction ion in either to increase or decrease the output current respectively depending on the size of the material it is to be used on. The major component of the machine that carry out such function is the transformer. This paper focuses on the design and construction uction of the welding machine transformer. The transformer is single phase which has shell type of lamination core and insulated windings of copper coils. In addition, the windings are given double insulation with the use of varnish solution which helps to prevent short-circuiting circuiting in the windings. With the help of Angle iron and lamination core, the core loss, iron loss in the machine is reduced to minimum. The voltage in Vin was determined directly from the mains of power supply and recorded.

Design And Construction Of An Arc Welding Machine

Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick " electrode " and the base material to melt the metals at the point of contact. Arc welders can use either direct DC or alternating AC current, and consumable or non-consumable electrodes. The welding area is usually protected by some type of shielding gas , vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

The arc welding is a fusion welding process in which the welding heat is obtained from an electric arc struck between the work or base metal and an electrode. They can use either direct DC or alternating AC current, and consumable or non-consumable electrodes. The welding region is usually protected by some type of shielding gas, vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated. First developed in the late part of the 19th century, arc welding became commercially important in shipbuilding during the Second World War.

The first arc welding method was developed in the 19th century, and it has become commercially significant within shipbuilding throughout II-World War. Nowadays it remains a significant process for vehicles as well as steel structure fabrication. This is one of the famous welding methods which are used for joining metals in industries. In this type of welding, the joint can be formed by melting the metal with the help of electricity. So due to this reason, it is named an electric arc. The main benefit of this welding is, a high-temperature can be easily developed for welding.
