An experiment study on corrosion rate variation of low welded carbon steel in a different solution

Abstract

The corrosion reaction of low carbon steel alloy welded with different shape(V &X) method is investigated after relives stress by tempering at (600°C,) for (30)minute then specimens divided in three groups, first normalizing, the second group annealing, third group Quenching, all groups heated to(750°C,)then cooling with still air, in the furnace &water according to its heat treatment sort then immersed in three kind solution, acidic solution (0.5M HCl) basic(NaCl) & distal water for one month each (7days) take the weight to compute rate of corrosion in welded zone as weight loss.
