Tailored aluminum blanks, such as structural automotive components, are formed by gas tungsten arc welding a plurality of aluminum or aluminum-alloy sections. Preferably, a backup plate having a shallow longitudinal groove or a plurality of longitudinal grooves and a beveled electrode are employed. A preferred embodiment comprises the use of a multi-torch assembly for initial cleaning and subsequent smoothing of the resulting weld.

Method and apparatus for gas tungsten arc welding tailored aluminum

A method and apparatus for recycling cans is disclosed. Discrimination of overweight conductive material from acceptable conductive materials from a mixed material input, while maintaining a high level of acceptable material recovery is achieved by control of the input to the separation system, as well as control of the separation mechanism.

Method for recycling cans

In a method of making a resistance welding electrode of the type having a copper or copper-base alloy body member and a coating on a surface portion of the body member, the coating defining an outer work-contacting surface of the electrode, and the coating being of a material selected from the group consisting of nickel, berylium, cobalt, iron and high melting point alloys of the foregoing, the improvement wherein the coated surface portion of the body member is shot-peened prior to coating.
