Nov 20, 2020 · Pre-heating metals is an additional, but often crucial step in welding applications. Pre-heating metal before welding decreases the temperature difference between the welding arc and the material being worked on. It ensures the rate of cooling in a finished weld is slower, lowers the chance of cracking, and allows hydrogen to diffuse out.Get Price
Apr 22, 2010 · Modern boilers will typically have controls to prevent this happening more often than perhaps every minute and your hot water temperature will vary wildly.
