Importance and Calculation of Heat Input and Arc Energy

What is Heat Input (HI):  In arc welding, energy is transferred from the welding electrode to the base metal by an electric arc. When welder initiate the arc, the welding electrode and base metal is melted and weld pool is generated. This weld pool results due to the energy supplied through the power source. Energy […]

Welding Positions

This article is about Welding Position involved in fabrication of Pressure Vessel, Piping and Pipelines. Different welding standard specifies different welding positions for welder. Welding position is specified as per the position of work piece before and during welding. Position of welding is specified in ASME section IX and EN ISO 6947. Welding position is
