Company Profile  
FILWEL industrial hardfacing and build-up wires, thermal spray wires and automatic welding systems are manufactured to precise specifications and standards to ensure consistency in quality and performance.
The wires are categorized broadly as follows:
Low alloy build up wires
Low and medium alloy steel hardfacing wires
High chromium carbide and complex carbide iron hardfacing wires
Stainless steel cladding wires
Cobalt base alloy hardfacing wires
Nickel base alloy hardfacing wires
Thermal spray wires for flame and arc spraying
The compositions of the weld deposits are precisely controlled to obtain the desired optimum microstructures to render the desired properties for the recommended welding applications.
Wear resistance needs to be improved whenever a component is exposed to wear due to high or low stress abrasion, cold or hot abrasion, metal-to-metal or metal-to-earth abrasion, impact, corrosion, thermal fatigue, compressive loading or a combination of any of these. Mostly, more than one wear mechanisms act causing the component to wear. Wear resistance can be increased by overlaying the component either by welding or thermal spraying. The microstructure of the deposit must ensure that maximum resistance is offered to the wear which takes place due to particular combination of the mechanisms causing wear to the component. The selection of an appropriate build-up and overlay alloys and the welding procedure therefore play an important role in combating component wear and maximizing performance.
The procedures for rebuilding and hardfacing components vary greatly depending on applications and service conditions. A particular alloy and method of application may work effectively in one area but may produce mediocre results elsewhere. A reduced component wear can be achieved by well-planned maintenance program which will increase production and saving in cost per ton of aggregate production obtained.
Please consult our experienced metallurgists/specialists/engineers for the right selection of the alloy/s and the procedure.
