Submerged arc welding is an automatic or semi-automatic welding process widely used for welding large structures and thick plates. Its biggest feature is that the arc burns under the flux during welding, forming a stable and deep-penetrating weld.

Advantages: High production efficiency: Submerged arc welding uses automatic or semi-automatic welding equipment and has fast welding speed. The welding process is carried out continuously without frequent replacement of welding rods, which greatly improves production efficiency. Especially effective for long welds and thick plate welding. Megmeet SA1000/SA1250 submerged arc welding machine can provide a stable welding process and meet the needs of heavy-duty welding.

High welding quality: The weld seam produced by submerged arc welding has high strength and stable quality. The penetration formed during the welding process is large, which is suitable for high-demand welding occasions. Since the arc is covered by the flux, welding defects such as pores and slag inclusions are reduced, and the welding seam is beautifully formed.

Disadvantages：High equipment cost: The cost of submerged arc welding equipment is relatively high, and it requires a flux recovery system and a wire feeding system. The initial investment is large and suitable for large-scale production enterprises.

Inconvenience in welding small parts: Submerged arc welding has certain requirements on the size of the welded workpiece and is suitable for larger or thicker workpieces. For small parts or precision welding, submerged arc welding is less efficient and less flexible than electrode arc welding.

Stick arc welding  is one of the most traditional and common forms of welding and is widely used in maintenance, construction and field work. This process uses an electric arc to melt the electrode and workpiece to form a weld.

Advantages:Simple equipment and low cost: The electrode arc welding equipment has a simple structure, a small initial investment, and does not require complex auxiliary equipment. This makes arc welding ideal for small to medium-sized businesses and on-site repair work.

Disadvantages：Low production efficiency: The welding speed of electrode arc welding is relatively slow. Welders need to frequently change welding rods, which can significantly reduce productivity during long welds or large-scale welding tasks
