FAQ
What is hardfacing?
Overlap welding can increase the size of the welded workpiece. It is a kind of surface engineering to recover the welded parts or the deposited metal, which has unique properties. Hardfacing using a welding heat source, form a molten metallurgical bond between the surface of the base material and the material deposited on a surface engineering surface. Its purpose is to borrow welding, in the parts of the deposition of one or more layers of material, to obtain the required wear-resistant, heat-resistant, corrosion-resistant, and other special properties deposited layer.
What are the types of overlays?
There are four main types of overlays.
- Abrasion-resistant hardfacing: to reduce the abrasive abrasion, corrosion, impact, or cavitation of the welded surface of the hardfacing layer used.
- cladding hardfacing: to make the surface corrosion resistance, in carbon steel or alloy steel base material on the hardfacing of a certain thickness of filler metal.
- Isolation layer hardfacing: Welding of dissimilar materials, or special requirements, to ensure the quality and performance of the joint, to do isolation of the base material in advance.
- Thickening hardfacing: on the surface of the weld, joint edges, or to restore the required size of the component to add metal.
What is the connection between welding and cladding?
Welding and welding overlay are two different technologies, and there is no relationship between them.
Welding: Welding is a manufacturing process and technique of joining metals or other thermoplastic materials such as plastics using heat, high temperature, or high pressure.
hardfacing: hardfacing, as an economical and rapid process method for surface modification of materials, is becoming more and more widely used in the manufacturing and repairing parts in various industrial sectors. It can make the most effective use of the hardfacing layer. It is desirable to use hardfacing methods with less dilution of the base material, higher deposition rates, and excellent hardfacing layer properties. i.e., high quality, efficient and low dilution rate hardfacing techniques.
What are the main types of hardfacing alloys?
Hardfacing alloys mainly include. Iron-based wear alloy, nickel-based wear alloy, cobalt-based wear alloy, tungsten carbide wear alloy, ceramic composite, etc.
What are the methods of hardfacing?
Flame hardfacing; manual arc hardfacing; submerged arc hardfacing; melt electrode gas shielded hardfacing; tungsten argon arc hardfacing; plasma arc hardfacing; electro-slag hardfacing.
How about MOQ of your wear products?
Our product has no limit to quantity, it can be ordered according to customer requirement.
What’s the service life compare with Hardox series?
Generally speaking, our bimetallic overlay wear plate is 4.5~8 times than Hardox series in service life.
How long is your delivery time?
Generally it is 5-10 days if the goods are in stock. or it is 15-25 days if the goods are not in stock, it is according to quantity.
Do you provide samples ? is it free or extra ?
Yes, we could offer the sample for free charge.
What is your terms of payment ?
We accept TT,LC.If you have good credit, we can accept OA.
Do you provide after-sales service?
Our company has a professional after-sales service team, with many years of experience not only on hardfacing products and applications, but also on the operation of application equipment. We are able to quickly solve customer’s problems. If there are any quality problems, the responsible person will provide reasonable solutions within 12 hours after being notified.
