Abstract
A method of making a solenoid actuator by laser direct metal deposition can comprise heating with a laser an outer surface of a circumferential groove of a solenoid tube blank constructed of a first material to create a heated area and depositing a second material upon the heated area to form a layer of second material. The second material can melt and then cool to thereby bond to the solenoid tube blank. A bore can be defined in the solenoid tube blank such that the bore includes an interior surface having a ring of second material disposed between a pair of portions of first material.
