== == 95% Argon 5% CO2 is most commonly used for spray MIG.
For welding 8 mm thickness metals, common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding (SMAW - Shielded Metal Arc Welding). The choice depends on the type of metal and specific requirements.
Arc welding is a type of welding using electricity to heat and fuse metal together. In order to control the process the heat must be controlled by varying the current. MIG (Metal Inert Gas) welding uses an inert cast to protect the weld from the air at extreme temperatures during the welding process. You can find a more detailed explanation of <a href=" http://www.trade-equip.co.uk/blog/?p=969 ">Arc Welding here</a>
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.
You can do Shielded Metal Arc Welding (stick) with an appropriate electrode. If the machine has a high frequency arc stabilizer then you can also TIG (tungsten inert gas) weld aluminum. Wire feed processes require a DC machine
One type of welding is tube welding. Another type if mig welding.
What type of welding can we use LPG ?
Transformer type welding machine
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
spray or sprinkler irrigation:It is method of applying of water in the form of a spray,somewhat as in ordinary rain, as is done in the garden lawn sprinkling. it is more effective type of irrigation.

SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
