The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.

You have oxygen and acetylene to blend into the tip for a flame. It will be regulated by adjusting the regulators on the bottles and the welding handle will have adjusting ability for the temperature you need for the metal you are welding.

When you weld steel you need to make sure that oxygen in the air is kept away from the weld while it's being formed. Otherwise the iron in the weld burns in the oxygen and forms a poor weld. Electric welding rods are generally coated with a flux which forms a gaseous shield around the weld point and keeps away the air.

Some welding processes (MIG for example - MIG stands for metal inert gas) do not use a flux coating but have an arrangement where argon or CO2 is passed to the weld point to keep the air away in a different way.

While welding as it is known today did not come about until the 19th century, primitive welding processes have been in existence for thousands of years. Metal tools and weapons have been discovered dating back to 1000 B.C.E. It was during the Bronze Age that humans first learned to fuse two metals together using heat. The Iron Age brought about increased use of fusing procedures. In the Middle Ages, blacksmithing was developed, which joined two metals through the use of fire and hammering.

intermittent welding (also known as skip welding) is a pattern of welding that allows the weld joint to cool by welding in a series of "skips" on opposite or far sides from the last bead. This pattern is often used for thin material as it is likely to warp if overheated.

The term"counter flange" is used in Europe to refer to a mating flange to make up a flange pair. For example a "counter flange" attached to a pipe must have the same bolt circle diameter, number of bolts, and size of bolts and pressure rating at the equipment nozzle flange provided by an equipment manufacturer.

welding current decides the electrode burn off rate, depth of fustion, geometry of weldments. welding voltage decides shape of fusion zone and weld reinforcement.

It would be an excellent idea. You will be working with powerful welding arcs and open flames as well as large bottles of flammable gases. It would also probably be a good idea to open your business as a limited liability corporation (LLC) to protect you and your family's personal assets. Good luck!

Depends on a lot of things. Slickest work, but most expensive - TIG. Cheapest - arc (stick) welder. Reasonably user friendly and inexpensive - wire-feed arc/ MIG welder.) Most versatile - Oxyacetylene. Oxy will give have the biggest heat affected zone and is the hardest to use (IMO). If your kart is really thin wall tubing you can forget about the stick welder and even the MIG will be quite tricky.

This is used differently in different countries. But generally, if a welder is contracted to do say 100 weld joints, of a 1" pipe, then the total work involved is 100" dia welding work. If 100 weld joints of a 2" pipe is 200 weld work and so on.

use duck tape it works on everything : D i have to agree, adhere it if you can, otherwise use a VERY low heat propane torch. Acetylene burns WAY too hot, and you won't get a good arc going over 2 types of metal. Also, I don't know if you can find a compatible filler rod though. If you do get the metals to stick together, becareful, if wont be very strong. Good luck The proper way to join aluminium pipe to copper is to use a threaded adaptor on the aluminium and add a copper adaptor . you then solder the copper.
