The transformation of weld forming is the results of dual functions of arc shrink and surface tension change.
焊缝成型的变化是电弧收缩与表面张力变化双重作用的结果。

Dacron polyester fibers have a high resistance to burning. They tend to fuse and shrink away from the flame, forming a bead that is very hard after cooling.
The material of the present invention has wide responding voltage range, may shrink in different voltages, and has the features of convenient control, easy forming and wide application range.
