Interfacial structure and properties of galvanized steel sheet joined by pulsed arc brazing process;

Study on technology of cast iron parts' repair with arc brazing

Based on the experimental research on the filler metal spreading and the wetting behavior in arc brazing process,the governing equations and the boundary conditions of the filler metal droplets under the actions of gravity,surface tension and the arc pressure are conducted.

A 5kW light beam brazing equipment has been developed and tested.

For resolving the flaws and capacity lacks of traditional MCM substrate equipment,we have developed a new type of vacuum brazing equipment.
