Consumable electrode type arc welding contact tip.

摘要

A welding contact tip for use on a consumable electrode type welder has a core part (1) having a bore (3) for guiding a consumable electrode (4) and capable of supplying welding current to the consumable electrode (4), and a main part (2) which embraces and supports the core part (1). The core part (1) is made of a heat- and wear-resistant conductive metallic material such as a chromium-copper alloy, while the main part (2) is made from a less-expensive material such as copper, a copper alloy, aluminum or an aluminum alloy.
