WIPO Patent Application WO/2011/031022
Kind Code:
A2
Abstract:
The present invention relates to a welding wire used in arc welding such as gas metal arc welding and flux cored arc welding using a protective gas and submerged arc welding using a flux, and provides a welding wire comprising: a core layer which is melted and turns into droplets due to the heat of the arc during welding; and an ionization potential layer which is formed on the surface of the core layer and consists of an element having low ionization energy, the welding wire being devised so as to exhibit a stable arc and metal transfer mode thereby making it possible to reduce the occurrence of short circuiting and spattering and so improve the quality of welding.
