Welding Equipment – A Guide To Choosing THAT IS Right For You

Oxy-Acetylene Welding Equipment

Welding by using gas dates back to the middle of 1800’s where the combination of oxygen and hydrogen were used in the making of jewelery.

Today we work with a different mixture of oxygen and acetylene which along can produce a flame temperature in excess of 6000 deg f. This sort of equipment is not only useful for welding, but additionally to heat resources for bending and straightening, brazing and slicing.

An oxy-acetylene outfit is normally portable, versatile, and less costly than a electric welding create, and by using the correct recommendations, ลวดเชื่อมเหล็กหล่อ rods and fluxes, almost any metal can be welded, heated or cut. This equipment is ideally suited to the welding of thin sheets, tubes and pipes however, not economical for thick area welds.

Arc Welders

Arc welding or stick welding requires a higher level of skill and mastery of certain tactics. Ideal for welding on thicker, rougher metals using a flux coated stick electrode fusing the task pieces together.

In order to avoid porosity and attain the perfect weld travel speed, it is very important remove excessive scale, 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 be welded, cast iron, stainless steel etc.

The electrodes must be replaced as the heat accumulates and the stick melts down leading to a molten weld puddle on the task piece fusing the work pieces together. The weld must be cleaned when completed due to the flux electrode forming a slag blanket on the weld bead. Utilizing an arc welder is really a relatively slow process and is fantastic for the more experienced user.

MIG Welding

MIG welding is generally a lot easier than gasoline or arc welding. A spool of weld wire is constantly driven by way of a feeding technique through the MIG gun because the trigger is pulled, consequently unlike arc welding you don’t have to constantly replace electrodes.

Handful of practice is required to setup the wire feed speed plus the power. The wire speed must be adjusted to suite each electric power 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) runs on the weld wire with a center main of flux which eliminates the need for gas shielding and will be offering easier, portable welding outdoors and on dirtier metals. Both operations of welding have become fast and allows you to weld the thinnest and thickest of metals. The very first thing to decide when buying a MIG welder is what you are likely to weld, and how often. If you are likely to weld thicker metals, then a welder with higher amps is required, but for thinner metals like automobile bodywork, any welder with a minimum setting greater than 30 amps will be unusable. Welding for long periods can cause the machine to overheat, so a welder with a lover (turbo welders) will be a big account for heavier or industrial make use of.
