Description

The present invention relates to a surface pad material for welding, and more particularly to a surface material for welding used for preventing the weld metal from dripping in lateral arc welding.

For example, as shown in Japanese Patent Application Laid-Open No. 8-215890, a surface pad material has been conventionally used in order to prevent the weld metal from dripping when performing lateral arc welding. Conventionally, as such a surface pad material, as disclosed in the above-mentioned publication, there has been only a structure corresponding to only a straight portion.

Recently, in-situ robot welding using a ceramic surface pad has been developed to save labor and weight, and along with this, not only the conventional ceramic surface pad that supports only straight lines, but also column corners.
