PREHEATING DEVICE OF C TYPE FILLER METAL FOR WELDING

摘要

The present invention provides a filler metal preheating device for welding, which continuously preheats filler metal having a C-shaped cross section. To achieve this, the filler metal preheating device for welding, which preheats the C-type filler metal by electricity, comprises: a pipeline which is attached to a welding machine and guides filler metal therein; and multiple electrode parts which are installed in two points separated from each other on the pipeline and allow one polarity of each power source to be connected thereto.
