The second group belongs to the students of professional schools and/or university of electrical engineering, line controllers, welders, electronic technicians, all low-skilled electricians with working experience not less than 1 year in the relevant profile.
Manual Metal Arc Welding (MMAW)
Electrode welding/stick welding
Shielded metal arc welding, also known as manual metal arc welding, or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
On the first group are included simple employees (painters, test workers, or plant personnel who do not have to know technical safety regulations, eg plant cleaners, mechanics, welders, crane drivers, etc.) with a minimum age of 18 years old.
Metal Inert Gas Welding (MIG Welding)
A welding process in which an electric arc forms between a wire electrode and the workpiece metal, which heats the workpiece metal, causing them to melt and join. The used shielding gas, is an inert gas (Argon or Helium).
The third group includes electromechanical, electro-technical personnel, all the specialists in the plant, substations, distribution plants, power grids and the electrical personnel working in telecommunication companies.
OXY - Fuel Welding
Oxy-fuel welding, commonly called oxy-acetylene welding, or gas welding and oxy-fuel cutting, are processes that use fuel gases and oxygen to weld and cut metals.
The fifth group of electrical technical safety belongs only to masters, senior electrical technicians and engineers on the plant.
Technical Safety in Electrotechnology – 4th Group
The fourth group of electrical technical safety belongs to young technicians and engineers, personnel at power plants, substations and electrical networks, electrical technicians, electrical engineers.
Tungsten Inert Gas Welding (TIG Welding)
Tungsten gas arc welding, also known as tungsten inert gas welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.
A welding process in which an electric arc forms between a wire electrode and the workpiece metal, which heats the workpiece metal, causing them to melt and join. The used shielding gas, is an active gas, usually a mixture of CO2 and Argon
IWS is a training programme with an internationally recognized diploma, developed from the International Welding Institute IIW, as part of the qualification scheme for the welding coordinator according to EN ISO 14731.
