Dear Sir, As we all of us known too and always talking about mild steel and carbon steel material. As I know that, carbon percentage makes a difference to differentiate carbon steel and mild steel. As mild steel has low carbon percentage as compared to carbon steel. But I want to know that as carbon steel comes in IS2062 category, then mild steel has to be study by which code? Or if we say IS 2062 for mild steel plates, then we can concluded that grade C is mild steel while grade A is carbon steel. Is it right. Basically, I want to know, above which carbon % , material is said to be carbon steel and below which mentioned as mild steel. In which code or standard it is mentioned?

Dear Experts   I need the following information with the reference of the code / standard.   01.    If the electrodes are kept in the store and are not in sealed container, then can we use them after Baking as per the manufacturer's recommendations or not. Please do give the code / Standard  reference 02.    The job as per our WPS is supposed to be heated at 100 Degrees Celsius, how to check the temperature, I do not have the measure Gun, 03.    As per the WPS the voltage should be 15 to 17 Volts, but is done at 20 Volts, the current used is 100 Amps as required. What is the effect of this +3 Volts. Material is WCB and it is only for overlay.   Thanks for the information in advance.   Nachhattar Singh     PLEASE THINK BEFORE PRINTING .
