DJM ceramic composite spare parts (weldability wear-resistant bar/liner) of engineering

weldability wear-resistant bar/liner Chocky Bar is one of the highly alloyed chromium white iron wear parts and looks like chocolate. the composite layer wear-resisting property is than high Cr material 3-4 times The mild steel backing plate has very good welding performance while bearing high impact.

This product is very easy to use. It's easy to be cut and welded on curved surface without pre-heat or after heat treatment. It's easy to be transported as it's very small. It's an ideal small area repairing wear part without too much welding time. We have a complete range of specification and are able to customize and develop according to customer's requirement. Comparing with normal High Cr wear resistant casting wear parts, this product's service life is 2-4 times longer.

 

This practice is suitable for Chocky bars only.

Note: For severe curves with a radius of less than 305mm, or inside curves, it is advisable to notch the mild steel backing plate opposite the “V” to assist forming. (Figure A)

The Chocky bar may crack during bending. This is normal.

1.        Clean the surface to which chocky bar will be welded.

2.        Tack weld one end of the chocky bar(as per the welding procedure) in at least 3 places by 15mm minimum length per weld(Figure 1)

3.        Outside Curves: Hammer down unwelded end of bar with a soft face hammer to bend bar to match mating radius. (Figure 2)

4.        Inside curves: Starting the center strike bar with a soft face hammer to bend bar to match mating radius. (Figure 3)

5.        Cutting Details:   High pressure abrasive water jet cutting is the preferred cutting method. cutting by abrasive disc is an accepted practice.
