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.

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.
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.
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.
1. _________ is the process of joining metal parts of fusion. The process of joining metal parts by fusion is known as arc 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.
There are a few commonly used welding process. The top used are shielded metal and arc welding.

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.
The welding process that uses a resistive heating system for metal deposition is known as Resistance Welding. In this process, electrical resistance is utilized to generate heat at the interface of the materials being joined, which causes them to melt and fuse together. This method is commonly used for spot welding and seam welding, particularly in the automotive industry for joining sheet metal components. The efficiency and speed of resistance welding make it suitable for high-volume production.
