On Steel Belt No.11 Welded Endless Belt #1

DYMCO employs plasma welding mainly,
which is appropriate for thin stainless steel,
rather than TIG and laser welding.
The picture below is cross section of the welded area in a 0.3mm-thick belt. Half-round stripe areas are melted by welding heat, while Diamond-shaped black points are positions where hardness was checked. In this way we know hardness and other characteristics in steel grades and welding conditions.
