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

Waterjet cutting


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)


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.
