Manual metal arc welding (MMAW), also known as stick welding, is a fusion welding process that uses a consumable electrode coated in flux to create an arc between the electrode and the workpiece. The heat generated by the arc melts both the electrode and the base metal, producing a weld pool that solidifies to form a strong joint. The flux coating protects the molten weld pool from atmospheric contamination and helps in the formation of slag, which can be removed after welding. This process is versatile and can be used on various metals and in different positions, making it popular in construction and maintenance applications.

What is filling pass in welding?
Filling pass is a welding process which function to filling filler metal inside welding groove before capping process be execute
What is the recommended welding amperage for joining two pieces of metal together?
The recommended welding amperage for joining two pieces of metal together depends on the thickness and type of metal being welded. It is important to consult the welding machine's manual or a welding professional for specific recommendations.
How hot is metal after its welded?
The temperature of metal after welding can vary depending on the type of metal and welding process used. In general, the metal can reach temperatures over 1000 degrees Fahrenheit during welding. It is important to allow the metal to cool down slowly after welding to prevent it from warping or cracking.
What are welding sparks called?
The sparks generated during welding are called welding sparks. They are tiny fragments of molten metal that separate from the welding material or workpiece due to the intense heat generated during the welding process.
What is the process of joining metal by fusion?
1. _________ is the process of joining metal parts of fusion. The process of joining metal parts by fusion is known as arc welding.
In which process is the electrode used in welding?
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.
The most commonly used welding processes are?
There are a few commonly used welding process. The top used are shielded metal and arc welding.
What is the process of joining metal parts by fusion?
1. _________ is the process of joining metal parts of fusion. The process of joining metal parts by fusion is known as arc welding.
What is the significance of the arc welding process?
The significance of the arc welding process are:-1. Flux Shielded Manual Metal Arc Welding is the simplest of all the arc welding processes.2. The equipment can be portable and the cost is fairly low.3. This process finds innumerable applications, because of the availability of a wide variety of electrodes.4. A big range of metals and their alloys can be welded.5. Welding can be carried out in any position with highest weld quality.6. The process can be very well employed for hard facing and metal deposition to reclaim parts or to develop other characteristics like wear resistance etc.ARSHAD H BHUTTOSALES ENGINEER-LINCOLN ELECTRIC WELDING PRODUCTS
What determines the temperature of the manual metal welding arc?
The temperature of the manual metal welding arc is primarily determined by the welding current, the type of electrode used, and the arc length. Higher welding currents generate hotter arcs, while different electrode materials can influence heat distribution and efficiency. Additionally, maintaining an optimal arc length ensures consistent heat application, affecting the overall temperature during the welding process. Factors like shielding gas and environmental conditions can also play a role in temperature variations.
What are the three types of machines used in manual metal arc welding?
I am not sure your question is clear enough but here I go... Stick Arc Welding (AC or DC), MIG (Metal Inert Gas) and TIG (Tunsten Inter Gas). All three of these are the basic metal welding machines.
