• Plate products either on drum or flat.

• Technique used for welding hardfaced rolls.

• Flux powder buries the arc thus slower weld pool cooling.

• Flatter product.• Ideal for dynamic

Questions + Answers• The client wants to make a coal handling chute from T200X,

he is worried about the sticky nature of the wet coal :– With the overlay positioned in the same direction as the

material flow, the sliding coefficient is very good. The material polishes in service almost to a mirror finish (30% Cr)

• The client is uncertain as to the correct overlay direction on cut to size pieces :– For most applications, this will not affect the lifetime

of the component. In an abrasive environment with a high level of errosion (small granular size), the overlay should be placed at 45° to avoid errosion between the weld beads.• Can the overlay come away from the base material? :

– This will not happen with a quality product, there is a perfect bond between the two materials (weld). The product conforms to the international standard for clad plates.

Questions + Answers• Do overlay plates resist to impact? :

– It is true that as a general rule, overlay materials are better adapted to the problems linked to tangential abrasion. A quality product can absorb « moderate to high » impact, each application must be studied.

• Overlay plate with 30% Cr has good corrosion resistant properties, doesn’t it? :– The alloy does indeed have excellent corrosion

resistant properties, the mild steel base plate however certainly does not. We can consider other products with a stainless steel base in 304 or 316 for example (even 310).• He client insists on having countersunk holes in the

liners, but finds the cost of inserts to be too high : – The best solution is an inclined plasma torch, this

gives a perfectly acceptable hole quality and costs significantly less than welded inserts.
