TIG Welders – Lightweight Welding Power

tig weldersTIG welders are commonly available as a Tig AC/DC power source that allows manual electrode welding as well as TIG welding. Modern machines contain microprocessors that give full digital control that results in perfect tig welds. TIG welders of this nature are rated from around 170 A to 300A, they are lightweight, portable and excellent welding machines suited for construction and maintenance work.

Larger TIG welders will run from 400 to 500A output. Machines of this nature also fully digital controlled. Applications include plant construction, aerospace and shipbuilding, pipeline construction and installations

When TIG welding, the operator has more control over the whole process of welding. Unlike other welding types Tig welders use tungsten electrodes that are non consumable. Tungsten is used as the melting point is extremely high, allowing the operator to introduce a filler rod to the weld. Many in the welding industry use tig welders to weld non ferrous metals such as magnesium, copper, and aluminum as well as stainless steel.

The Advantages of TIG Welders

The electrodes used with TIG welding are non-consumable, while other types of welding, like tig welderarc and mig welding use electrodes that are consumable. There are advantages with both methods but with TIG welders there is no need to stop in the middle of a project and replace the rod that has been used up. As one might expect, stopping at a critical point can cause an imperfection in the quality of the finished product. With the undisturbed work that can be done with the TIG system, the overall quality is much better.

TIG welders are a good choice when working with non-ferrous metals like copper, magnesium, and aluminum.

Minor disadvantages of TIG Welders

If you have ever wondered why there are so many different welding techniques as well as equipment, the answer is simply that there are different situations that require welding of a different kind using an array of different equipment. For this reason tig welding is a somewhat specialized feild.

For one thing, TIG welding is more complicated and requires more skill and better training in order to carry it off right. The welder using a TIG welding machine must have much greater accuracy and control in directing the tig torch and using the filler rods. Maintaining the arc in the correct position and the right distance from the piece they are working on is critical.

Welding with a tig machine is more time consuming than most of the other methods, but you must remember that this time means the finished work will be much higher quality, making it worth the time it takes to complete. Wearing a quality welding helmet is essential as the arc created from tig welders is much brighter than conventional welders.

MIG Welding Basics

MIG welding stands for metal inert gas welding. It was originally used to weld non-ferrous metals such as aluminum. It eventually was used on steel too. It is a quicker method of welding as compared to other methods of welding.

mig weldingSome of the advantages of MIG welding include the speed of the welding process. It has the ability to weld many metals and many thicknesses of metal. The biggest advantage to MIG welding is that it can be automated so that the human element can be removed all together. That’s why robotic mig welders are commonly found is on an assembly line in an automobile factory. As mig welding machines utilize a wire feed system this makes them ideal for robotic purposes as they can carry a great amount of filler rod or wire.

Mig welding utilizes a wire feed technique which feeds a wire electrode from your welding handgun to the weld. This wire electrode is available in numerous coil capacities or spools dependent upon the welder sizing, that may contain 100s and perhaps 1000s of feet/meters of wire. The actual wire feed includes a pair of drive wheels to the wire plus a continual speed electric motor to move the drive wheels. The majority of Welders contain numerous features enabling timed feeds together with adjustable speeds.

You need the right safety gear. This includes a face mask to protect your eyes and skin. You also need to have a heavy leather jacket. Keep the jacket fastened all the way up. You need to wear heavy cotton pants and close toed shoes. Heavy work boots are best. Make sure that you are welding in a well ventilated area, and that you have some kind of barrier between you and others, and you have a warning sign that advises people to avoid the area.

When you start welding you need to make sure that you have the valve on the machine for the shielding gas is open. Your welding machine needs to be on, and the grounding clamp either on the metal or on your welding table.  Make sure that your metal is clean and sharp edges are ground down. Clean edges make your welds better. You can bevel the edges to create a valley for the weld if you choose to, this is more important on thicker metals.

After you have done that and set your machine up, it’s time to start welding. You want to make a zig zag or concentric circles with the tip. It’s smart to practice before you start welding. Make sure the mig welding machine is at the right setting. If you are getting holes in your workpiece your setting is too high. Your settings are too low if your welds are being formed in spurts. You have the right settings when your bead is nice and smooth.

Welding Types and Processes

welding types An outline of welding types and processes commonly used in industry and manufacturing

Micro Welding, represents systems and also devices specifically designed for the purpose of carrying out, as it implies, micro welding  for very small, thin, and fragile components by making use of closely managed heat energy.

Laser welding, is certainly one of the leading approaches the metalworking industries, because focused energy from laser device produces a higher quality of weld. lazer welding may also be used for many additional applications  such as cutting, drilling, sealing, as well as scribing,  helping to make the process itself, multi purpose in nature.

Seam Welding works as a resistance welding procedure that creates a weld on the faying surface areas of overlapped components along an overall length of the joints. The weld can be created by overlapping weld nuggets, a consistent weld nugget or through forging the actual joints as it’s heated up to the welding temperatures by means of resistance to the flow of welding current.

Ultrasonic welding is often an industrial method in which high-frequency ultrasonic  oscillations are utilized to weld items together, usually plastics,  This specific form of welding is required to produce components and also parts  which are so tiny, complicated, or even far too fragile for any common welding methods. In ultrasonic welding, no other conecting techniques or glues required to bind materials with each other.

Hermetic welding is a welding procedure that doesn’t create a weld yet generates a seal. The primary point with hermetic welding will be to produce a complete leak-proof joint, which in turn cannot be offered via other standard welding process.

Projection welding can be described as flexible procedure designed for joining wire, sheet, machined & formed components in steel, for example  wire mesh, connection for mounting brackets, and so on for sheet metal construction, as well as welded nuts and bolts

Orbital welding apparatus has the capacity to produce premium quality, dependable welds regularly as fast as possible
A good orbital welding process is going to significantly outshine manually operated welders, numerous times paying for the cost of the orbital machines within the job.

Precision welding isn’t a specific welding procedure, but alternatively a collection of welding systems which opperate on a micro level to produce high quality welds . Precision welding is required on situations in which normally can be challenging to get in the regular approaches with welding. Almost all of the innovative styles of welding procedures drop within the class connected with precision welding.

Resistance welding consists of the creation of heat by means of transferring current through the resistance induced by the contact with the metal surfaces. Pools of molten metal are formed at the weld area as high current  is passed through the metal. Resistance welding comprises of the common welding types such as Arc, Mig and Tig welding
