Comment: I have a very large concern with the explanation of the 2/3 split of heat with the welding polarities. The book states that 2/3s your heat, in DCEN polarity, is concentrated in the electrode which is objectively untrue. GTAW welding in DCEP clearly has more heat. Every other source explicitly states the opposite case, that 2/3s of your heat in DCEN is in the base metal. Please take a moment to audit and correct such books, unless the ILM writers are leagues above their colleagues from other sources. Thank you, have a good day. Ben Craib

Comment: Thank you for the opportunity to give my feedback. I have been teaching second year for several years and have come to the conclusion that the Second year math examples in the module do not give enough explanation on the actual process of the formula. Could the concepts be broken down into more detail and explain how each process actually works? The general consensus from each class is, 80% do not understand the process or have never understood the process. I feel this will make the students more successful going forward to Third year and their career.
