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 has always worked on improving welding education.
ESAB's Knowledge Center contains a vast amount of information for gaining a welding education from multiple perspectives: learn to be the welder, the engineer, the welding inspector, and the project manager. ESAB helps you expand your welding knowledge by choosing from our vast categories.
Cladding of Ni-alloy UNS N08825 in Pressure Vessel Applications: Optimized Efficiency with a Complete Solution.
Cladding of Ni-alloy UNS N08825 in pressure vessel applications: optimized efficiency with a complete solution.
Strip overlay cladding of Ni-alloys is one of the most cost sensitive applications in pressure vessel fabrication. Compared with cladding of austenitic alloys, Ni-alloy cladding has a major effect on the cost of the vessel production. Performing Ni-alloy overlay cladding in a controlled manner is essential to meet cost targets and optimize efficiencies.The cladding consumables, the actual cladding procedure and the equipment used are critical process parameters for fabricators seeking success in this application. The following key factors affecting cost efficiency will be discussed:
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 ...
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 ...
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 ...
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 ...
