What are 4 welding positions for plate welding?
flat, horizontal, vertical and over head position
What is over head position welding?
When the weld is made from under the joint.
Where can I go to get a cheap welding fume extractor?
Well, welding fume extractors aren't that cheap in general, but you're best hope is finding a used fume extractor, or to buy a new one online. A product search will show you the best fume extractors, although I would look for one under $1200.
What are the advantages of AC equipment over DC equipment in arc welding?
Ac (alternating current) equipment is cheaper because you dont need rectifiers to change current from alternating current to dc (direct current) and there is no arc blow associated with ac (alternating current).
What is spot welding?
Spot Welding is a process where two pieces of overlapping metal are welded by applying an electric current through two contact points. The interface of the parts creates current resistance which produces heat. The two metals form a "button" type weld when pressure is applied. The welds will be of the approximate size of the contact points and the filler metal consists of the base materials only (additional material is not generally added). The equipment used for spot welding in smaller operations would consist of a set of "tongs" that apply current and pressure to the parts being welded. This process can be accomplished using a portable unit or an automated process such as with automobile manufacturing.Workpieces are held together under weight applied by anodes. Normally the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness extend. The procedure utilizes two molded copper combination anodes to gather welding current into a little "spot" and to at the same time cinch the sheets together. Driving a vast current through the spot will dissolve the metal and shape the weld. The appealing element of spot welding is that a considerable measure of vitality can be conveyed to the spot in a brief span (roughly 10-100 milliseconds).[2] That allows the welding to happen without over the top warming of the rest of the sheet.The measure of warmth (vitality) conveyed to the spot is controlled by the resistance between the terminals and the size and length of the current.[3] The measure of vitality is coordinated the sheet's material properties, its thickness, and kind of cathodes. Applying too little vitality won't dissolve the metal or will make a poor weld. Applying a lot of vitality will soften an excessive amount of metal, launch liquid material, and make a gap as opposed to a weld.[4] Another element of spot welding is that the vitality conveyed to the spot can be controlled to deliver solid welds.Projection welding is an alteration of spot welding. In this procedure, the weld is limited by a method for raised segments, or projections, on either of the workpieces to be joined. Warmth is amassed at the projections, which allows the welding of heavier segments or the nearer dividing of welds. The projections can likewise serve as a method for situating the workpieces. Projection welding is regularly used to weld studs, nuts, and other screw machine parts to the metal plate. It is additionally oftentimes used to join crossed wires and bars. This is another high-generation prepare, and numerous projection welds can be masterminded by reasonable outlining and jigging

What is a sentence using explosion?
There was a explosion over there. An explosion of fire lept from her eyes as he told her that he had killed her dog.
What are the disadvantages of ssb over am?
drawbacks of conventional am
What is conventional symbols with definition?
conventional symbols are those symbols which are commonly used all over the world.
Can you Welding after pwht for P91 material?
No.You should not do that because the welding heat leads to over tempering of P91 which reduces the toughness and ductility...
A primary advantage of the electronic ignition system over conventional ignition systems is?
a primary advantage of the electronic ignition system over conventional ignition system is?
Does lacquer coating on tinplate affect welding?
Yes. However, there are paints designed to be compatible with welding as they are designed to protect the surface of the plate from corrosion while in storage. In every code or specification, it is specifically stated that welding should be done on clean metal. Welding over paint is discouraged.
Why Dc welding sets are prefered over AC welding sets?
Often because with DC, it is possible to change the direction of the weld current for the task at hand.
What is welding gas?
Welding gas can refer to two things. In torch welding, it is either a fuel gas such as acetylene or MAPP or oxygen, and in arc welding (MIG, TIG, etc...) it refers to any of the inert gases such as carbon dioxide or argon that is pumped over the weld pool to protect it from atmospheric contaminants.
How long does a supernova explode?
The initial explosion is over in seconds
What are the advantages of having engines with dual injectors over the conventional engines with single fuel injector?
dual injectors spray more fuel into the engine causing a bigger explosion in the combustion cycle. but, with the added fuel there is added pressure and usually there is a second sparkplug to accomidate for the extra fuel to ignite.
Is their a over the counter drug the can make you pregnant?
No - imagine the population explosion if that were possible ...
