摘要：This work investigated the effect of heat input
variation on the mechanical properties of ASTM A300. Three
welds were made with varying voltages and currents by using
Flux Core Arc Welding (FCAW) process and the heat input
was computed. Nine test specimens were prepared using API
1104 standard. The specimens were subjected to tensile test,
impact test and hardness test. Analysis of variance (ANOVA)
was used to determine effect of the various heat input on the
mechanical properties of ASTM A300 obtained at the heat
affected zone. The result obtained showed that heat input has
significant effect on the tensile strength, toughness and
hardness of ASTM A300 steel.
