What is the function of the welding cable?
Welding cable is designed for use in electric arc-welding machines to power an electrode, a specially designed metal rod, that conducts a charge. The charge carried by the electrode is needed to produce an electric arc, the heat source, between the electrode and the metals being welded.
What are the functions of welding fluxes?
The main function of weld flux is to oxidize the base and filler materials during the welding process. Weld flux is a substance that is almost inert at average room temperature but can be intensely reducing when exposed to higher temperatures to prevent metal oxide formation.
What is the main function of the welding power source?
The primary function of a welding power source is to provide sufficient power to melt the joint. However with MMA the power source must also provide current for melting the end of the electrode to produce weld metal, and it must have a sufficiently high voltage to maintain the arc.
What is the function of an electrode holder?
The primary function of the electrode holder clamp is to support the electrode, guaranteeing a good electrical contact for current passage; it should also guarantee sufficient electrical insulation for the welding operator.
What are the 5 welding positions?
What Are the Different Welding Positions?
- Flat position.
- Horizontal position.
- Vertical position.
- Overhead position.
What are 4 welding processes?
There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW).
What are three functions of flux?
(i) To dissolve any oxide that is present on metal surface. (ii) To prevent corrosion or oxidation by excluding air. (iii) It enables spelter to flow easily along the joint. (iv) It enables solder to adhere to metal surface.
