Abstract
Hydrogen cracking is one of the most common defects that get induced in the welding of the pipes or we can say that in pipeline welding. Here in this paper pipes are of X80 steels, the use of this steel had been come into picture since 1985 and it becomes very helpful in transporting oil and gases through long distances and effect and remedies of hydrogen cracking are discussed in order to obtain good weld characteristics in electric arc welding. To prevent cracking and to achieve high strength the X80 steels are made of ultra-low carbon, ultra-low sulphur, micro-alloying elements (niobium, vanadium and titanium) and molybdenum.
