Question
(a) An Investigation of the CaCO3-CaF2-K2SiO3- SiO2-Fe flux system using the Submerged Arc Welding Process on HSLA-100 and AISI-1081 Steels was conducted in a series of experiments. In this investigation, the welding fluxes with differing chemical compositions were prepared. Several welds using each flux were made on AISI-1018 steel base metal. The ANOVA results of hardness measurements (in Brinell scale) of five welds using each of four fluxes are presented in Table 2. Table 2: ANOVA of hardness measurements Source of df Sum of squares variation Mean of (SS) Flux Error Total 3 16 19 squares (MS) 1023.6 608.3 (i) Complete the ANOVA table in Table Q2(a) Fo
