Mining, Quarries/ Earthmoving

Part: Buckets

Base material: Un/low alloy steel

Problem:

Wear on bucket and bucket teeth due to abrasion
,friction and impact by coal, sand, stone etc.
Equipment looses efficiency, causing increase in
operating costs.

Solution:

Protect bucket lips, sides and other wear areas by
applying a wear resistant high alloy Chromium
Carbide material.

Welding process: SMAW (Stick electrodes)

Welding material: A) GOLD 750 (HB63)

B) GOLD 760

JAW CRUSHERS –CRUSHER JAW PLATE

Used to crush (reduce) hard materials such as coal, stone etc.

Crushers are normally made form a wear resistant Manganese steel.

Problem:

The high impact and compression causes the Jaw
plates to wear out and the crusher looses crushing efficiency.

Solution:

Weld repair

Welding process: SMAW (stick electrodes)

Welding material:

GOLD 740

HAMMER MILL CRUSHER (COAL PACTORS )

widely used crusher system Made from austenitic manganese steel or low alloy cast steel

Problem:

The Hammers crushing the raw materials
are subject to extreme impact/pressure
and abrasion and tend to suffer wear and
tear

Solution:

Rebuild worn hammers by using one
of the following Welding materials.

Gold 740  for restoring dimension
and thereafter apply 2 layers of GOLD
750 OR GOLD 76O  for maximum protection

Wear on Crusher Housing (Bearing)

Repair welding : GOLD  740 or GOLD 710
Machinable weld deposit

Machine: EXCAVATOR

Part: Track pads

Base material: Low alloy cast steel

Problem:

Wear on truck pads due to friction and pressure.
Equipment looses efficiency, causing increase in operating costs.

USE GOLD  710 or GOLD 740  FOR REPAIR
