Description:
CHE40
is the most
popular mild steel welding rod with titania type coating. It is able to
provide excellent welding performance and satisfactory weld can be obtained
in all position welding. It is widely used in ordinary strength mild steel
structures especially suitable for intermittent welding to sheet steel and
small work pieces as well as cosmetic welding with smooth and shiny
appearance.
