Stick welding (properly known as Shielded Metal Arc Welding or SMAW) requires use of a covered stick electrode, a metal rod that’s coated with a material called flux. An electrode holder is used to hold and supply current to the stick electrode, causing it to melt and deposit molten metal. As the electrode melts, the flux coating breaks.

Shielded Metal-arc Welding (SMAW) is the simplest and used for many joining processes. More than 50% of industrial and maintenance welding currently is performed by this welding process. In this welding operation, an electric arc is generated by touching the tip of a coated electrode against the workpiece and withdrawing it quickly to a distance sufficient to maintain the arc as shown in the. How Welding Works. Welding is a process where an electrical arc melts the two metals being joined, sometimes along with the use of a melted a welding rod or filler metal to create a strong joint. There are no chemical reactions involved in the welding process. However, because molten metal reacts with oxygen in the air, creating metal oxide on the welded surface that can weaken the weld.

Shielded Metal Arc Welding (SMAW) is also called Manual Metal Arc Welding (MMAW) or flux shielded arc welding or popularly known as stick welding.
In SMAW we generally use consumable types of able electrode means flux covered on the rod. Because of flexibility and simplicity, SMAW is the world’s best welding process.

Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool causing g is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
In addition to melting the base metal, a filler material is typically. Shielded metal arc welding (SMAW) is the simplest, least expensive, and mostly widely used arc welding process (Figure 2).It is often referred to as ‘stick welding’ or manual metal arc welding.
This process produces coalescence of metals by heating them with an arc between a covered metal electrode and the base metal work piece.
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. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc.
Shielded metal arc electrodes from the following groups were tested: aws types e and e 16 stainless steel, ecocr-a co-cr hardfacing alloy, enici-ni, a mn- cr buildup alloy, e carbon steel, and em low-alloy steel. Flux-cored wire electrodes of this last group also were tested. Shielded metal arc welding electrodes are covered with flux, Purpose of flux is as follows; During welding, the flux material decomposes and produces fumes.
These fumes shield the molten weld pool from the atmosphere. Shielded Metal Arc Welding is a write-in text that progresses from basic theory to specialized techniques. It focuses on the shielded metal arc welding (SMAW) process. A unit on welding problems provides solutions that students can use when they encounter an issue/5(4).

The recommended way toFile Size: KB. Because the electrodes used in the shielded metal arc welding process are consumable, it is necessary for the person performing the welding to periodically replace the electrode. The need to chip away slag and replace spent electrodes make this.
Shielded Metal Arc welding is one of the most widely used processes, particularly for short welds in produc-tion, maintenance and repair work, and for field construction.
The following are advantages of this process: 1. The equipment is relatively simple, inexpensive, and portable. The fume plume contains solid particles from the consumables, base metal, and base metal coating.
For common mild steel arc welding, depending on the amount and length of exposure to these fumes, most immediate or short term effects are temporary, and include symptoms of burning eyes and skin, dizziness, nausea, and Size: 1MB. Air Products Welder™s Handbook MIG/MAG welding principles Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation.

Stick welding is technically defined as “Shielded Metal Arc Welding”. The term “stick welding” is a common slang term that the welding industry has adopted becuse the electrode that welds the metal comes in the form of a “Stick”.
The slang term “Stick Welding” comes from the stick type of electrodes used to weld like in this. Gas shielded metal arc welding In gas shielded metal arc welding, an arc is generated between solid or flux-cored a (tubular cored) wire electrode and a base metal, while the arc is protected with a shielding gas or gas mixture as shown in Fig.
Depending on the type shielding gas, this process is of also known as CO. Shielded metal arc welding is one of the most versatile joining processes in industry and it is extensively used the world over.
In India nearly 90% of the welded fabrication is done by this process and even in the most advanced countries like USA, USSR, Japan, and the West European countries it accounts for nearly 60% of the metal.Welding fumes are a complex mixture of potentially toxic fumes and noxious gases.
Some of the frequently observed diseases resulting from exposure to welding fumes and gases were discussed in Section It is, however, imperative to notice that welding fumes are a complex mixture of metals and metal oxides, and exposure to welding fumes is unique.Secondary Welding Output.
