摘要：
A method of bonding together at least two long, metal alloy segments, of turbine components, such as turbine blade segments (18, 19, 20 and 21) by: putting a melting point depressant between the segments at bond planes (34) between contracting segments; forming a heated zone across the segments and a heated front (32); where melt pools (36) form in a molten zone (38) at the heated front which front (32), pools (36) and zone (38) continuously move and pass along the bond planes (34); where crystal re-growth (35) occurs along the bonding planes to form bonds (34) between the individual segments (18, 19, 20 and 21) behind the moving molten zone (38).
