Laser Cladding and Hard Facing for the Oil and Gas Industry

Leave a Comment

Laser cladding and hard laser facing are welding techniques that provide a protective surface coating on metal parts. Also called laser metal deposition (LMD), laser cladding utilizes a focused laser beam to generate heat, and clad material is simultaneously fed into the resulting melt pool on the targeted surface area of a metal component. The […]

Hot & Cold Wire Feed Laser Welding and Laser Weld Overlay

Leave a Comment

Welding involves joining two metal parts using heat to melt them together. Weld overlay involves adding to the surface of a metal component to recover lost dimensions [ Additive remanufacturing] or changing the chemistry of the metal surface [ corrosion resistance]. Using the laser as the heat source, hot and cold wire feed welding are […]

What Is Weld Overlay?

Leave a Comment

While welding is often used to join metals together, it can also be used as a protective technique. Weld overlay, also known as weld cladding, is the process of melting a protective layer of metal atop another metal surface. The application of laser light heats and melts the cladding metal onto the parent metal, creating […]

Welding vs. Brazing vs. Soldering

Leave a Comment

Welding, brazing, and soldering are three different processes that join metals. They all use heat to join metal primary differences between welding, brazing, and soldering are the melt temperatures of the metals or materials used in the process and what is being melted. There are many different welding techniques but here we will discuss only […]

Thermal Spray vs. Laser cladding

Comments Off on Thermal Spray vs. Laser cladding

This blog is meant to explain the differences between the thermal spray and laser cladding processes and help you understand the physical differences between each process. What is Thermal Spray? Thermal spraying refers to a group of coating processes in which finely divided metallic or nonmetallic materials [ceramics] are deposited in a molten or semi-molten […]

Comments Off on Introduction to the Laser Cladding Process

Laser cladding—also referred to as laser metal deposition or Laser weld overlay—is a manufacturing technique used to add metal material to the surface of a component. It is generally used to create a protective coating that increases the functionality of the part or product. However, it can also be used to repair worn or damaged […]

Comments Off on Hardfacing Methods

Hardfacing delivers a wear-resistant and hard coating of material on the surface of a worn component or a new component that will be subject to wear. There are various methods that can be used to apply the hardfacing layer. Common methods include: Arc Welding Oxygen-Acetylene Thermal Spraying Diode Laser Hardfacing The different hardfacing techniques provide […]

An Introduction to Laser Welding for Dissimilar Metals

Comments Off on An Introduction to Laser Welding for Dissimilar Metals

  Many industries and applications require dissimilar materials to be joined for chemical, structural, and economic reasons. Combining dissimilar metals in a Weldment or for a weld overlay allow the use of the best properties of each metal. All industries benefit for this and is a primary importance when the overlay [cladding] is used in […]

An Introduction to Autogenous Welding

Comments Off on An Introduction to Autogenous Welding

Welding is a manufacturing process used to join two or more individual pieces. It can be broadly categorized into two classifications: fusion welding and solid-state welding. Fusion welding encompasses all of the processes that utilize direct heat applied from an external source to fuse or melt contact surfaces of metals to weld them together, while […]

Guide to Laser Welding

Comments Off on Guide to Laser Welding

What Is Laser Welding? To understand laser welding we must step back and generally describe what welding is. Welding is joining similar materials of different shapes and similar melt temperatures. These materials are typically the same material. The welding process concentrates heat at the interface to melt the edges and upon solidification creates a structurally […]
