摘要： A pulse welding period includes a first peak period for supplying a first peak current to a welding wire, a first base period for supplying a base current smaller than the first peak current to the welding wire, a second peak period for supplying a second peak current to the welding wire after alternately repeating the first peak period and the first base period (n−1) times (n is an integer equal to or larger than 2), and a second base period for supplying the base current to the welding wire. The second peak current is larger than the first peak current, and droplets are transferred from the welding wire during the second peak period or the second base period.

摘要： A method of creating a clad metal part is provided. The method includes explosion bonding a plate comprised of a base layer and an interlayer. The explosion bonded plate is then cut into bars which are roll bonded with a clad layer. Ultimately a part is fabricated from the roll bonded bar. The solution enables parts to have material combinations and resulting physical properties more optimal for an application than a single bonding process.
