What welder to use on autobody?
It depends on what you are welding. If you are doing welding on mild steel go with MIG welding; if it is aluminum or stainless steel then use TIG welding. TIG welding gives a nice looking finish. If you just want to get a decent look, then MIG is preferable and easy.
Which gas is use in gas welding?
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
Co2 oxygen both use same time in mig welding?
CO2 and O2 can not be used in the same time for shielding gas in MIG welding, it would create too much oxidation of the molten metal.
Studying At A MIG Welding School Can Advance Your Career?
If you are interested in finding a good school that can teach you how to weld, you should be able to find a program that provides MIG welding training. This will help trainees acquire sufficient knowledge to perform a type of welding that is a lot faster to complete than the traditional "stick welding" process. MIG welding is also referred to as Gas Metal Arc Welding. The process was pioneered in the 1940s to allow non-ferrous and soft metals to be welded easily. MIG welding can either be a semi-automatic or an automatic procedure. It involves using a wire that is connected to a direct current. The wire is used to join two pieces of metal together. This method also makes use of argon to shield workers from contaminants that are present in the air in the workplace. Aside from its ability to join non-ferrous materials and sot metals, there are a lot of advantages that come from using MIG welding. This procedure is a continuous welding process that is much faster to complete than a regular welding method. MIG welding equipment also uses a shielding gas that protects the arc of the weld to make a clean seam with minimal visible splatter. Learning the techniques involved in MIG welding will allow you to use different procedures that will join metals and alloys together. However, there are also some disadvantages to using MIG welding techniques. These include the complexity of the machine, as it requires a constant flow of gas and a direct current to complete a welding procedure. It also needs wires that can be move to a certain distance. The MIG technique is entirely different from traditional stick welding. Therefore, welders will need to acquire skills that will assist them in using the tools and methods correctly. Since the equipment requires argon gas, MIG is not possible in open places where the wind blows heavily. However, MIG welding procedures are common in manufacturing companies. If you have completed a program at a MIG welding school, you will be prepared to work in manufacturing and heavy industry.
Which gases are used in normal welding process?
Depends on what you think of as normal welding. Gas welding use oxygen-acetylene. MIG/TIG use Argon. MAG, use an argon-something mix. Depending on what materials you are welding, there are some more options tha might be used.
What is welding flux?
The term flux means to clean. Not all welding processes use a flux. Stick welding electrodes contain fluxing agents. MIG hard wire doesn't but flux-cored MIG wire does. TIG does not as the rods are bare. Most brazing applications require flux. Gas welding usually doesn't except for certain metals.
What kind of welding machine do you use to weld your muffler?
I would use a wire feed MIG, or a oxy-fuel torch. If arc welding, use a low power. It's really easy to burn through exhaust pipes and mufflers.
Explain the principle behind arc welding.?
Arc welding uses an electrical current to create enough heat to melt metal. Any type of welding that uses an electric arc is technically arc welding. However, most people use the term 'arc welding' to mean shielded metal arc welding (SMAW), or 'stick welding'. SMAW, MIG, and flux core wire welding use the filler metal as both electrode and filler; TIG welding uses an electric arc to heat the base metal and a separate filler rod to add metal to the weld.
how does laser welding machine work？?
The welding process of laser welding is very similar to the traditional MIG TIG (arc welding) welding process. However, in contrast to MIG, TIG welding, Laser welding is much cleaner than conventional arc or Tig welding, and thus helping to reduce the risk of contamination. It's also more precise, easier to automate, and provides for bonding of much thinner metals, and provides for much greater tensile and bending strength. Laser welding is a process that uses a laser beam to join metals or thermoplastics together to form a weld seam. As such a concentrated heat source, laser welding can be performed at ultra-fast welding speeds in thin materials, while narrow, deep welds can be produced between square-edged parts in thicker materials. Often one would use a wire feeder from a laser welding machine supplier to fill the weld seam. how to use laser welding machine Since laser welding machine is different from MIG and TIG, the operation of laser welding machine is the simplest. Usually, MIG, TIG, and other welding processes require a welder who is very familiar with the welding technique to operate. Unlike laser welding machines, you only need to set the parameters needed for the laser to penetrate the surface, and you can use the parameters set at that time without changing the thickness of the material in the future. There are almost no consumables for laser welding machines, but the more common ones are gases, lenses, and copper nozzles. Lenses and copper nozzles are usually included by the laser welding machine supplier when the machine is packaged. These are enough to last for many years. Laser welding machine production methods and costs, accessories. The laser welding machine is basically composed of optical components ( There are galvanometer, beam expander, field lense and other important optical devices in the optical path system of the laser welding machine.), laser welding head, automatic wire feeder, control board (laser welding machine control system), laser generator and so on. The YAG laser welding machine will also include the YAG laser generator (yttrium aluminum garnet crystal).
What is the Best MIG Wire to use when welding Cor-Ten Steel?
wire will be 70s-2 and the gas is cver shield #6 wich means 75%=ar,and 25% co2
Did the North Vietnamese use MIG-21MF's?
They had the MiG-21PFM.
Mig welding or arc welding?
Technically speaking, MIG welding is arc welding because it uses an intensely hot electrical arc to heat and join the metal together. Usually arc welding means stick welding. The difference between the processes is the manner in which the filler metal is applied. With MIG welding, the filler metal is usually applied with a wire fed through a gun type device with an inert gas such as argon shielding the weld. Arc (or stick) welding uses a solid electrode of the same type of metal as is being joined shielded by a layer of flux. The method of welding depends on the user's skill and what is to be welded.
