In this way, any welding result can be optimally reproduced.sp.info the Base Metal Thickness Essential Variable for Welding ...If the thermal energy introduced by the welding arc is rapidly removed from the weld, then the amount of base metal melting that occurs will decrease. Under particularly adverse conditions, the heat from the arc can be removed out of the welding area so rapidly that no melting of the base metal occurs. We then get a lack of fusion defect being created. This is particularly evident in welding processes where the heat input into the weld is ve…See more on welderdestiny.comsp.info PlasmasWith a nitrogen plasma, metal plates up to three inches thick can be cut at speeds up to 15 inches per minute; with an oxygen plasma, half-inch steel can be cut at 160 inches per minute.
