The very low carbon steels (C < 0.15%) can produce porosity when welded at high speed. This problem can be overcome by increasing the heat input. Steels with carbon contents between 0.15% and 0.25% are preferred for welding, as they rarely present weldability problems if the impurity levels are kept low.Estimated Reading Time: 13 minssp.info Institute Of Infectious Disease and Molecular MedicineFor information on South Africa's response to COVID-19 please visit the COVID-19 Corona Virus South African Resource Portal.sp.info 82. Metal Processing and Metal Working IndustryIn gas-shielded arc welding, a blanket of inert gas seals off the atmosphere and prevents oxidation and contamination during the welding process.
