1. Fusion welding means that the two surfaces to be joined and the filler metal are meling during welding and then solidifying in similar menner to local casting process. 2. In oxyacetylene welding process, the welding is done using oxidizing flame only. 3. Explusive welding process produces strong joints of dissimilar materials that are not weldable by arc.

The welding parameters to be used to butt weld a metal alloy are being evaluated. In order to set up the welding machine, the melting factor for the metal (f2) has to be determined. The welding machine can deliver 4000 watts of power and the heat transfer factor for the welding process (f1) is 0.9. The final weld bead consists of 8 0% filler metal and 40% parent metal. The melting temperature of the filler metal and the parent metal is the same 2540 deg F. The cross-sectional area of the weld bead is 0.5 sq inches. The rate at which filler metal is added to the weld is 1 cu inch per min. Conversion factor 1 Btu = 1055 J and 0 deg F = 460 deg R Calculate the melting factor.
