Difference between electric arc welding and submerged arc welding
Principle: Difference between electric arc welding and submerged arc welding are both MIG arc welding, SMAW electrode and the workpiece to form a weld using hot melt welding arc between the core and the workpiece, using melted coating to protect slagging gasification, and submerged arc welding is the use of solder melting for protection.
Features:
1. SMAW equipment is simple, submerged arc welding equipment complex and expensive compared to the price; welding productivity, SMAW is relatively low, and submerged arc welding using a larger current efficiency several times;
2. before welding assembly, electric arc welding requires low, which is high;
3. welding quality, electric arc welding depends on the operator's level, which is as long as the parameters of the right choices, you can get high-quality welds;
4. labor intensity, electric arc weldingr large, tsubmerged arc welding due to automation, low intensity;
5. working conditions, electric arc welding large, submerged arc welding is small;
1. welding materials, can weld carbon steel, low alloy steel and stainless steel, in addition to hard fusion, can not easily oxidized metal welding;
2. welded structure, electric arc welding is most suitable for welding of complex structures, short and irregular welds, which rules most suitable long weld on large structures, such as the barrel ring, longitudinal seam;
3. the thickness of electric arc welding is less than 3mm is not used, although the thickness is not limited, but considering the efficiency, often used in 3-40mm, submerged arc welding due to the welding current, it is not used below 5mm, the maximum thickness of up to 650mm.
Welding equipment and tools: electric arc welding is simple, cheap, often welding machine, welding handle, ground clamp, face mask and aids; submerged arc welding is device complexity, price relative to more expensive, often welding power, welding carriage, control systems, send wire systems and wheel frame, welding positioner machinery and other auxiliary equipment.

6. welding position, electric arc welding all-position, submerged arc welding because of the flux own reasons, currently only in the flat, horizontal position;
