Effects of welding on materials
WebJul 1, 2013 · The rotating arc welding process provides very low heat input (0.78 kJ/mm). The higher heat input leads to grain growth in the weld pool, while the low heat input provides no time for grain... WebFeb 10, 2024 · The increased WT allows a rise in temperature for proper phase change of the material and improves material flowability and mixing. Similar to the RS trend, in some cases, with an increase in WT, joint strength increases initially and then drops [ 15, 28, 31 ]. In some studies, joint strength decreases with a rise in WT [ 18, 19, 24 ].
