It is always a technical problem to punch holes in the wear-resistant plate. Then, can we punch holes in the wear-resisting plate at all? Here we will briefly introduce the processing method of drilling on wear-resistant plate. By the second part of the article, we will introdce how to weld wear resisting plate.
Perforating (sinking hole, straight hole)
Equipped tools: drilling machine, iron suction drill, carbon arc gouging and plasma cutting machine, gouging tools (500 type DC welding + air compressor + Air Gouging gun + Carbon Arc Rod).
Straight hole processing: with plasma cutting directly.
Sinking hole processing: First, drill the hole from the surface of the base plate to the joint surface of the base plate and the wear-resisting layer, then use the carbon arc air gouge to break through the wear-resisting layer, after the wear-resisting layer breaks out the slope of the counterbore hole, use the grinding wheel to grind.
Wire Electrical Discharge Machining
Equipped tools: DC welding machine, oven, can also use Gas metal arc welding.
The base plate and the wear-resisting layer make two bevels respectively; generally use carbon arc air gouging, beveling. (Flat Carbon Arc bar is recommended)
WELDING BETWEEN BASE PLATE AND BASE PLATE WITH NORMAL WELDING Rod,
stainless steel is welded between the wear-resisting layer and the base plate, which is used as the transition layer;
Wear-resisting layer and wear-resisting layer are welded by wear-resisting welding rod or welding wire;
Finally, use a grinding wheel to smooth it out.
Full Weld, operation should be kept short arc, multi-layer alternating welding, in the welding process hair-like stress seam is a normal phenomenon.
When back welding, vertical welding, horizontal welding, should use less current and voltage; in addition, must use protective gas.
