Rectifier Welding Machine and Other Stick (SMAW) Welding Equipment

Blog Archives

The rectifier welding machine works on AC power source and is capable of delivering ac high frequency as well as dc welding current. There are various types of rectifier welders available in market, however, all of these are same in functionality and working. These units have main three parts, the transformer, the movable core reactor, as well as the rectifier cell meant for changing ac to dc. We bring you some of the best products in this category along with all details and best prices. For more information, kindly get in touch with our support team.

The arc welding machine joins metals by a fusion welding process. The arc may be generated from AC or DC power sources. This arc will produce intense heat of approximately 6500°F, which in turn melts the metal at the join between two workpieces. This arc, manual or mechanically guided towards the weld pool to supply the electrode as filler metal. The shielding gas or slags used to minimize the oxidation. The cooling of molten metal on solidification may lead on to a metallurgical bond.
There are many welding processes available depending upon the need but commonly used welding processes are MIG - Gas metal arc welding (GMAW), TIG - Gas tungsten arc welding (GTAW), Stick - Shielded metal arc welding (SMAW) and Flux-cored arc welding (FCAW).
Both the processes are arc welding but in MIG welding process shielding gas is used to prevent the oxidation at the welding site. Arc welding process uses flux-cored wire or electrode which acts as the same as shielding gas. Arc welding process to be performed in open only while MIG welding can be accomplished in ventilated indoor.
The arc welding process uses electricity to create a very hot arc which melts the two surfaces which get joined by filler material on the cooling of the weld pool which is protected by gas, slag, etc. This is also being called as manual metal arc welding (MMAW) or stick welding process.
The arc welding process needs a power supply to create an electric arc between electrode and material being welded, which can be either direct current (DC) or alternating current (AC). Both DC and AC current have their pros and cons but in general principle, DC current is used for ferrous material while AC current is preferred for non-ferrous metals.
The arc welding process has many advantages although this is not a perfect welding process. The process is advantageous as it has a high speed of welding, little distortion, less smoke or sparkles, smooth welding, economical, can be carried out in any environment, strong joint and corrosion resistance joint can be achieved.
The arc welding has a better penetration rate than a MIG welding process once you are working with a thick metal which requires deeper penetration of the arc welding to produce a strong joint instead of a MIG welding process.
