Key notes: General: Typical H.I from 1 – 3.5 kJ/mm Plastic state welding or Non-fusion welding CC or CV Polarity and Penetration ability Operation Factor vs Duty Cycle  Affection of Torch Angle MMA: Typical OCV : 50-90V and Operation range : 20-40V Arc blow because of Magnetic force (DC) –> Prevent by using AC Run Out Length (ROL) –> For measuring the welding Speed TIG: Typical OCV : 50-90V and Operation range : 20-40V Filler rod – consumables vs Electrode – nonconsumable HF – high frequency  Arc starting can Damage the equipments AC used for Al and Mg (Because of Best Cleaning … Continue reading CSWIP 3.1 WELDING PROCESSES

Key note: Storage Condition Dew point of Consumable Gas: – 60 Deg Filler material must be stored in an area with controlled temperature and humidity. MMA Consumables Core wire made by Rimming steel Weld properties controlled by covering Flux Silicon (De-oxidizer) added to Flux to avoid the Porosity inhibited by rimming steel Flux types comparison: Flux types identification: Impact test energy as per EN ISO 2560: Tensile strength or Yield Strength SS – ELECTRODE SMALLER THAN CS ELECTRODE BECAUSE OF LOWER ELECTRIC CONDUCTIVITY. TIG Consumables EB INSERT (SEE TERMS AND DEFINITIONS) Nitrogen will not be used for Ni,Ni-alloys and Mild … Continue reading CSWIP 3.1 WELDING CONSUMABLES
