Oxy-Acetylene Welding Equipment
Welding with the use of gas dates back to the center of 1800’s where the combination of oxygen and hydrogen were used in the making of jewelery.
Today we work with a different combination of oxygen and acetylene which mutually can produce a flame temperature more than 6000 deg f. This kind of equipment is not only used for welding, but also to heat elements for bending and straightening, brazing and cutting.
An oxy-acetylene outfit is normally portable, versatile, and less expensive than a electric welding setup, and by using the correct recommendations, ลวดเชื่อมเหล็กหล่อ rods and fluxes, nearly every metal could be welded, heated or lower. This equipment is ideally suitable for the welding of slim sheets, tubes and pipes however, not economical for thick section welds.
Arc welding or stay welding requires a higher level of skill and mastery of certain approaches. Greatest for welding on thicker, rougher metals using a flux coated stay electrode fusing the work pieces together.
In order to avoid porosity and attain the perfect weld travel speed, you should remove excessive level, rust, moisture, paint, essential oil and grease from the top of joints. Many different electrodes are available for the various types of metal that is to become welded, cast iron, stainless steel etc.
The electrodes ought to be replaced as the heat builds up and the stay melts down producing a molten weld puddle on the task piece fusing the task pieces together. The weld should be cleaned when completed because of the flux electrode forming a slag blanket over the weld bead. Using an arc welder is a relatively slow process and is ideal for the more experienced user.
MIG welding is generally easier than gas or arc welding. A spool of weld wire is constantly driven by a feeding system through the MIG gun because the trigger is pulled, consequently unlike arc welding you don’t have to constantly replace electrodes.
A small amount of practice is required to create the wire feed speed as well as the power. The wire speed needs to be adjusted to suite each ability setting, but with a little practice the correct settings are easily achieved.
MIG process (GMAW) requires the usage of a shielding gasoline which reduces spatter and makes very clean welds without slag blanket. Flux cored MIG welding (FCAW) uses a weld wire with a centre core of flux which eliminates the need for gas shielding and offers easier, portable welding outside and on dirtier metals. Both operations of welding have become fast and lets you weld the thinnest and thickest of metals. The vital thing to decide when investing in a MIG welder is what you are going to weld, and how often. If you are planning to weld thicker metals, a welder with higher amps is necessary, but also for thinner metals like auto bodywork, any welder with the very least setting greater than 30 amps will be unusable. Welding for long periods can cause the unit to overheat, so a welder with a admirer (turbo welders) would be a big concern for heavier or industrial use.
