LSAW (Longitudinal Submerged Arc Welding) and SSAW (Spiral Submerged Arc Welding) are both types of submerged arc welding processes used in the manufacturing of pipes. There are 10 differences between the two techniques:
Manufacturing Process: LSAW pipes are made by bending and welding wide steel plates, while SSAW pipes are formed by spirally bending and welding a strip of steel.
Pipe Diameter: LSAW pipes are typically used for larger diameter pipes, while SSAW pipes are used for smaller to medium diameter pipes.
Pipe Length: LSAW pipes are typically produced in shorter lengths and require fewer welding joints than SSAW pipes, which are produced in longer lengths and require more welding joints.
Welding Technique: In LSAW, the welding is done longitudinally, whereas in SSAW, the welding is done spirally.
Welding Quality: LSAW welding produces a better quality weld compared to SSAW welding, which can result in higher levels of defect rate.
Cost: LSAW pipes are typically more expensive to produce compared to SSAW pipes due to the higher labor and material costs involved.
Production Efficiency: LSAW pipes have a higher production efficiency than SSAW pipes, as they require fewer welding passes and less welding time.
Material Usage: LSAW pipes use more steel plate material than SSAW pipes, which can increase the overall cost.
Application: LSAW pipes are commonly used in industries such as oil and gas, whereas SSAW pipes are commonly used in water and sewage treatment plants, construction, and other industries.
Quality Testing: LSAW pipes undergo more rigorous testing than SSAW pipes due to their higher quality standards.
