Why Welding Electrodes Are Coated

Welding electrodes are also coated to create a protective shield around the weld to prevent atmospheric gases from infiltrating the weld material and weld area and generating contaminants like oxides. Consumable electrodes are coated to introduce any alloying materials that may be…

Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point-of-contact.

The electrode that is to be used depends on the type of welding process selected according to which a consumable or a non-consumable electrode is selected. Non-consumable electrode generally made of tungsten or tungsten alloy and used in TIG (Tung…

A presentation of Resistance-welding processes would start with the electrical resistance values that can be measured at the various interfaces present in the secondary circuit of a transformer when two overlapping metallic sheets are held between copper electrodes under a squeezing force.. Other examples of Resistance-welding would include more than two sheets, or less usual setups like that …

Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.

What is MIG Welding? MIG welding is an abbreviation for metal inert gas Welding. It is a process developed in the 1940’s, and is considered semi-automated.

The most widely used materials used in resistance welding electrodes are copper/chromium and copper/chromium/zirconium. These are used for high-grade steels and also for low carbon. To weld coated ste…

Welding Electrodes are the essential components in the process of welding. We use welding to join different materials permanently. In simpler words, welding electrodes are cylindrical shaped metallic rods, coated with flux and comes in varying lengths and radius.

Aug 17, 2012 … For today's post, we will discuss how to join metal

The electrode is coated in a metal mixture called flux, which gives off gases as it decomposes to prevent weld contamination, …

These processes use a welding power supply to create and maintain an electric arc between an electrode and the base material to melt metals at the welding point. They can use either direct current (DC) or alternating current (AC), and consumable or non-consumable electrodes.The welding region is sometimes protected by some type of inert or semi-inert gas, known as a shielding gas, and filler …
