ESAB Knowledge Center

Since Oscar Kjellberg's invention of the covered welding electrode in 1904, ESAB has played an integral part in the discovery and development of more commonly accepted welding processes than any other company.

ESAB's Knowledge Center contains a vast amount of information for the welder, the engineer, the welding inspector and the project manager.

How does the laser process work?

The laser cutting process uses a focused laser beam and assist gas to sever metallic plate with high accuracy and exceptional process reliability. The laser beam is generated by a resonator, and delivered through the cutting nozzle via a system of mirrors.

Advantages of laser technology Laser technology has the following advantages:

High accuracy Excellent cut quality High processing speed Small kerf Very small heat-affected zone compared to other thermal cutting processes Very low application of heat, therefore minimum shrinkage of the cut material It is possible to cut complex geometrical shapes, small holes, and beveled parts Cutting and marking with the same tool Cuts ...

Waterjet Cutting Process Basics

The most versatile process for shape cutting Highest precision cutting on virtually any material Can be combined with plasma or oxy-fuel on the same part Most versatile cutting process Water Jet cutting uses an ultra-high pressure stream of water to carry an abrasive grit. The abrasive does the cutting through a mechanical sawing action, leaving a smooth, precision cut surface.

Waterjet is the most versatile process, because it is able to cut almost any type of material. Limitations include materials that are highly brittle, such as tempered glass and some ceramics.

Water jet is a very precise cutting process. It has a narrow kerf width, allowing fine contours to be cut, and ...

What is Plasma Arc Cutting?

And how does it work? Plasma is defined in Websters as a ”collection of charged particles ... containing about equal numbers of positive ions and electrons and exhibiting some properties of a gas but differing from a gas in being a good conductor of electricity ...”. You can also think of it as an electrically heated gas stream. I like to think of it as a condition where all of the electrons from every atom are flowing from atom-to-atom, instead of just orbiting. Regardless of what’s going on inside a plasma stream, the way to cut metals with it is pretty straightforward. Take that stream of electricity flowing through a gas, and constrict it through a small orifice. Now that stream is really ...

The Basics of Plasma Cutting

Plasma Cutting Process Plasma cutting is the fastest cutting process on carbon steel, aluminum, or stainless steel. Plasma cutting can be combined with waterjet or oxy fuel on the same part. Plasma cutting can be use for precision cutting on gauge material up to 6” thick stainless. ESAB invented plasma cutting in 1955, and we've never stopped developing ways to make plasma cutters better and easier. ESAB's latest innovations in the plasma cutting process automation increase production with more consistent cut quality every time ... regardless of operator skill level: Plasma Arc Characteristics Plasma is defined in Websters as "collection of charged particles ... containing about equal ...

How Does the Oxy-fuel Cutting Process Work?

Most cost efficient process for carbon steel cutting. Can be combined with plasma, or waterjet on the same part. ESAB's experience with oxy-fuel cutting dates back to 1907.

Oxy-fuel cutting is a chemical reaction between pure oxygen and steel to form iron oxide. It can be described as rapid, controlled rusting. Preheat flames are used to raise the surface or edge of the steel to approximately 1800°F (bright red color). Pure oxygen is then directed toward the heated area in a fine, high pressure stream. As the steel is oxidized and blown away to form a cavity, the preheat and oxygen stream are moved at constant speed to form a continuous cut.

Only metals whose oxides have a lower ...
