ABSTRACT:
Metal articles are press-fitted together, using a lubricant dispersion comprising about 1-15 wt % colloidal graphite in isopropanol. The isopropanol is removed and the articles are then welded together at a joint to form a unitary weldment. The process is especially suitable for use on articles made from aluminum and aluminum alloys.
