The Wilkinson Welding Academy based in Worsley, Salford offer the Apprenticeship in Engineering scheme
The electrode holder clamps the end of the electrode with conductive clamps built onto its head. These clamps operate either by twist action or spring-loaded clamp action (Crocodile type).
Resistance welding is one of the oldest of the electric welding processes in use in the welding industry today. The weld is made by a combination of heat, pressure and time.
From December 2010 the new European standard, named (IEC/EN) 61000-3-12, which regulates the maximum levels of harmonic distortion produced by electrical equipment, came into effect.
The ‘Inverter welder’ has become a very popular choice in recent years. Inverter technology is a control system when applied to welding makes it
Single phase welding power sources are usually 230 volts AC. Often some older machines are referred to as single phase when actually they are two phases from a three phase supply (400 volts AC) with no neutral
HF Start High frequency is used to generate high voltage and low amperage using a spark gap assembly. The frequency can vary with the spark gap between 16000 Hz and 1000000 Hz. This method can cause electronic interference if the … Continue reading
Pure Tungsten (Green Tip) These electrodes are unalloyed, ‘pure’ tungsten. They offer good arc stability when using AC current with either balanced or unbalanced wave and continuous high-frequency stabilisation. Pure Tungsten electrodes are preferred for AC sine wave welding of … Continue reading
Mig welding is a process that was developed to meet the production demands of the war and post war time economies. The process utilises an electric arc power source and a continuously fed consumable wire that is shielded by gas.
