Automatic orbital welding Tunguston inert gas welding. This eliminates the possibility of manual errors in welding. It produces identical welds for hundred times hence accuracy in welding.

Orbital welding was first used in the 1960 `s when the aerospace industry recognized the need for a superior joining technique for aerospace hydraulic lines. Mechanisms developed in which the arc of the tungsten electrode rotated around welded joints tubes. Arc welding current is set up so that the control system automates the entire process. The result is more precision and reliable method than the manual welding method replaced.
Orbital welding became practical for many industries in the early 1980 `s when the supply / electric combination developed control system operated from 110 V AC and is physically small enough to be carried from place to place on a construction site in place for some welds. Modern day orbital welding systems offer computer control where welding parameters for a variety of applications can be stored in memory and called up when needed for specific applications. Certified welder skills thus built into the welding system, producing a large number of identical welds and leaving significantly less room for error or defect.

Orbital Welding Equipment

In the orbital welding process, tubes / pipes are clamped in place and orbital weld head rotates an electrode and electric arc around the weld to make the required weld. An orbital welding system consists of a power supply and an orbital weld head.

Power Supply: Supply / power supply control system and control of welding parameters according to the specific weld program created or recalled from memory. The power supply provides the control parameters, the arc welding current, the power to drive the motor in the weld head and switches the shield gas (es) on / off as needed.

Weld Head: Orbital weld heads are usually of the type covered and provide an inert atmosphere chamber that surrounds the weld joint. Standard enclosed orbital weld heads practical in welding tube sizes from 1/16 inch (1.6mm) to 6 inches (152mm) with wall thickness 'up to 0.154 inches (3.9mm) Larger diameters and wall thickness' can be accommodated with open style weld head.

Physics GTAW Process

Orbital welding process uses the Gas Tungsten Arc Welding (GTAW) as the source of the electric arc that melts the base material and forms the weld. In the GTAW process (also known as Tungsten Inert Gas process - TIG) an electric arc is formed between the tungsten electrode and the part to be welded. To start the arc, RF or high voltage signal (usually 3,5-7 KV) is used to break down (ionize) the insulating properties of gas and make it electrically conductive shield to pass a small amount of current. A capacitor dumps current into this electrical path, which reduces the arc voltage to a level where the power supply can then supply the current arc. The power supply responds to demand and supply welding current to keep the arc established. Metal to be welded is melted by the heat of the arc and fuses together.

Reasons for Using Orbital Welding Equipment

There are many reasons for using orbital welding equipment. The ability to make high quality, consistent weld repeated at maximum speed approaching the speed of welding offers many benefits to users:

o Productivity. An orbital welding system will drastically outperform manual welders, many times paying for the cost of the orbital equipment in a single job.

o Quality. Quality welds created by an orbital welding system with the correct weld program will be superior to manual welding. In applications such as semiconductor or pharmaceutical tube welding, orbital welding is the only way to reach the weld quality requirements.

o Consistency. Once the welding program has established an orbital welding system can repeatedly perform the same weld hundreds of times, eliminating the normal variability, inconsistencies, errors and manual welding defects.

o Orbital welding can be used in applications where a tube or pipe to be welded can not be rotated or where rotation part is not practical.

o Orbital welding can be used in applications where access space restrictions limit the physical size of the welding device. Weld heads may be used in rows of boiler tubing where it would be difficult for a manual welder to use a welding torch or view the weld joint.

o Many other reasons exist for the use of orbital equipment over manual welding. Examples are applications where inspection of the internal weld is not practical for each weld created. By making a sample weld coupon that passes certification, the logic states that if the sample weld is accepted, that successive welds created by an automatic machine with the same input parameters should also be sound.

Industries and Applications for Orbital Welding

Aerospace: As mentioned earlier, the aerospace industry is the first industry to recognize the need for orbital welding. High pressure system from the aircraft can have more than 1,500 welded joints, all automatically created with orbital equipment.

Boiler Tube: Boiler tube installation and repairs offer a perfect application for orbital welding. Compact orbital weld heads can be clamped in place between rows of heat exchanger tube welder where users will experience severe difficulty making welded over.

Food, Dairy and Beverage Industry: Manufacture of food, milk and drinks require consistent full penetration welds on all weld joints. Most of the tube / pipe system has a schedule for cleaning and sterilization in place. For maximum efficiency plumbing piping systems should be as smooth as possible. Every hole, gap, crack or incomplete weld joint can form a place for the fluid in the tube to be trapped and form a bacteria harbor.

Nuclear Piping: The nuclear industry with the harsh operating environment and associated specifications for high quality weld has long been an advocate of orbital welding.

Offshore applications: Sub-sea hydraulic lines use materials whose properties can be altered during normal thermal change the weld cycle. Hydraulic joints welded with orbital equipment offer superior corrosion resistance and mechanical properties.

Pharmaceutical Industry: Pharmaceutical process lines and piping systems provide high-quality water to their processes. This requires high quality welds to ensure water sources are not contaminated tubes by bacteria, rust or other contaminants. Orbital welding ensures full penetration welding without overheating occurring that could undermine the corrosion resistance of the weld end zone.

Semiconductor Industry: The semiconductor industry requires piping systems with extremely smooth internal surface finish to prevent the buildup of contaminants on the wall of the tube or welding joints. Once large enough, a build up of particulate, moisture or contaminant could release and ruin the batch process.

Tube / Pipe Fittings, Valves and Regulators: Hydraulic lines and liquid and gas delivery systems all require pipe with connector fittings. Orbital system provides the means to ensure high productivity and quality of welding. Sometimes pipes can be welded in place for the valve or regulator body. Here the orbital weld head provides the ability to produce high-quality welds in applications with restricted access to the weld joint.

The average person impression of how the weld metal is that you just fire-up the blow torch and run it along the edge of the metal seam to weld together. Or they may think you can just run that same torch in every type of metal and cut through it, like a safe-cracker in the film. But the reality is that professional welding actually involves some fairly extensive knowledge, and a bit of an art form that requires years of experience to master. Even so, if you want to learn, you can start with some simple techniques. Once you've mastered the basics and have an idea starter, then you can move on to more complicated skills that take longer to master.PrecautionsBefore you start any project, always think about safety precautions first. Tools and equipment can be replaced, you can not be replaced. You might think that getting burned is the worst thing that can happen in a welding accident. However, damage can happen to your eyes from strong light coming from the process. Some metal welding techniques using high voltage electricity to make the weld, which always increases the possibility of electrical or death if you are careless. When you start any welding project, be sure to wear proper helmet to protect your eyes, head and hair. And do not forget the protective gloves and clothing. Lastly, be sure to read and follow all the safety precautions that are written by the manufacturers of certain metal welding equipment you are using.Oxy-Acetylene Welding (also known as Oxyfuel Welding)This is the type of welding that the average person most familiar with, and which is often described as a casual "blow torch". However, although the oxy-acetylene welding is the most common type is known, actually using the techniques of the professionals. On the upside, it is less complicated and less expensive than other types of welding. However, oxy-acetylene is less common today because of less accurate, does not produce a clean weld bead and other methods can lead to weak weld joints because the cooling time is slower than the other involves welding techniques. Even so, if you are interested in learning how to weld metal, you may want to practice oxy-acetylene welding in addition to other types of welding. This would be a useful skill to have because it is the best type to use on common welding projects, such as a pipe or tube, and when you have to use welding equipment to perform repairs, bending and cutting.Arc WeldingThe most common technique used today is "Arc Welding". If you learn how to weld metal, you will definitely need to practice welding arc. Instead of using a gas torch, arc welding involves the use of high voltage electricity passed to a piece of metal. In Arc Welding, splash (or "arc") jumping across from one piece of metal to another cause enough heat to melt the metal and form a weld. This process is more desirable in many cases because it is more accurate and produces clean, strong weld. In the category of "Arc Welding" there are actually several different methods to choose from, depending on the type of metal welding work you need to do.Shielded Metal Arc Welding (SMAW) is probably the best when you have a large welds or welding metal in an unusual position, in which the rough welds are acceptable. With this method, electricity runs through an electrode rod (or "stick") that is completely melted, producing welded joints. On the other hand, MIG Welding, also known as Metal Inert Gas Welding, or Gas Metal Arc Welding (GMAW), it might be better if you are involved in a project that requires a metal welding speeds. With this technique you do not use a welding rod that you have to keep replacing as they melt. Instead, you use equipment that sends electricity through a metal tip that does not melt, and a separate piece of wire is fed continuously to the end of the melt and form a weld. TIG (Tungsten Inert Gas) Welding MIG welding is somewhat similar to, but better when working with thin materials where you need high-quality welds and speed is not important. When you learn you will also hear from other methods, such as Flux-Cored Arc Welding (FCAW), Submerged Arc Welding (SAW), Plasma Welding, etc. But do not worry too much about remembering all the various techniques. Only focus on one method at a time and get to the point where you feel comfortable that you know how to weld with that method before you learn something new.

Another method WeldingAlthough you will primarily be related to Arc Welding and Oxy-Acetylene Welding when you learn how to weld, you may hear about other types and are wondering what they are, such as Resistance Welding, Energy Beam Welding Welding and Solid-State. Do not let it overwhelm you now. Many of them are welding method is especially useful in large, specialized industrial applications and are not really affect you when you learn how to weld.

Arc Welding For A Start

Welding arc is where you'll find that most experienced welder welding began their career before branching out into various types of welding disciplines within the construction industry.

With arc welding that actually uses welding power supply / source to develop an electric arc between the electrode (welding rod) and the basic ingredients that you want to join combine them together at the point of welding. Direct current (DC) or alternating current (AC) is used together with consumable electrodes or non-consumption. Actual weld area is usually protected by some form of steam, inert gas welding or welding slag to protect the atmosphere, causing problems in the melt zone.

Arc welding did not occur until 1802, although some forms of alternative welding process does not go back to the Bronze Age and Iron.

A good way to describe the weld are: joining pieces of material together in the right way fusion.

As I mentioned earlier that there are many types of welding all, and the reason for this is that different types of applications require a particular category of welding jobs welding that would be suitable for the job at hand. A good example is if you welded high pressure pipe, the TIG (Tungsten Inert Gas) welding is commonly used in many cases because it is a correct application for certain types of welding activities, although the filling and capping of the following can be done with the TIG arc welding if required in the specification of work.

Benefits of arc welding and Opportunities

This is very useful to get some formal training, you decide to make a career in welding, for the simple reason that you can learn many things involved in the trade. For example, you not only learn different welding techniques, but also make you familiar with various types of welding machines are used in arc welding machine using the techniques themselves bevel grinding pipes and more.

It may be very surprised that when you are training to be an arc welder with experience how valuable experience is being gathered as a plumber at the same time, though they are two different jobs are actually two very closely related and are involved in getting the two tubes together at the end days.

As the welding arc welder, or anything for that matter, their welding skills will be given after class and find a job is not a problem because the recruiters are always looking for experienced welders in arc welding for a variety of industries around the world, is putting up a skyscraper in Los Angeles or welding pipes in Alaska, or somewhere in the manufacturing of vehicles in Detroit.

Welding is a skill that can be learned and as the most needed skills are excellent little dedication and a lot of practice. Nothing is stopping you want to learn to weld and get experience in arc welding.
