Types of Stainless Steel Welded Pipes by Welding Method
Stainless steel welded pipes are critical components in modern industry, valued for their corrosion resistance, strength, and versatility. These pipes are manufactured using various welding methods, each influencing the pipe’s mechanical properties, appearance, cost, and performance in different applications.
Choosing the right welding method is essential to ensure the durability and suitability of SS welded pipes for specific industries, from construction and chemical processing to food production and high-purity systems.
In this article, we explore the main welding techniques used in the fabrication of welded stainless steel tubes, highlighting how each method impacts their characteristics and recommended uses.
Stainless steel welded ERW pipes produced by Ganyeah
1.ERW Pipes (Electric Resistance Welding)
ERW welded SS pipes are produced by passing an electric current through the edges of a stainless steel strip, heating them until they fuse under pressure. This process creates a longitudinal weld without using filler material.
Key Features:
High-speed, cost-effective production
- Suitable for thin- to medium-wall thicknesses
- Clean weld with minimal distortion
Typical Applications of ERW Stainless Steel Welded Pipes:
- Water and gas distribution systems
- Structural components and scaffolding
- Fencing and architectural supports
2.EFW Pipes (Electric Fusion Welding)
EFW welded SS pipes are fabricated using an electric arc that melts both the base metal and a filler material, forming a strong, fused joint.
Key Features:
- Ideal for thick-walled and large-diameter pipes
- Provides strong welds suitable for high-pressure conditions
- Common in critical industrial systems
Common Applications:
- Power generation piping
- Pressure vessels and boilers
- Chemical and petrochemical process lines
3.TIG Pipes for Hygienic Applications
TIG (Tungsten Inert Gas) welding produces precise, high-quality welds using a non-consumable tungsten electrode and inert gas shielding.
Key Features:
- Excellent weld aesthetics and surface finish
- Suitable for thin-walled stainless steel welded pipes
- May use filler material depending on application
Best Uses of TIG Welded Stainless Steel Pipes:
- Food and beverage processing pipelines
- Pharmaceutical and sanitary tubing
- Instrumentation and high-purity gas systems
4.Laser Pipes for Precision Applications
Laser welding applies a concentrated high-energy laser beam to join materials with pinpoint accuracy, resulting in narrow, clean weld seams.
Key Features:
- High precision and minimal heat distortion
- Ideal for high-speed automated production lines
- Clean appearance suitable for decorative applications
Typical Applications:
- Decorative stainless steel tubing
- Automotive and aerospace components
- Precision-engineered piping systems

5.Plasma Arc Pipes for Industrial Use
Plasma arc welding uses a constricted arc with higher temperatures than TIG, allowing efficient welding of thicker stainless steel materials.
Key Features:
- Stable arc with deep weld penetration
- Suitable for medium to thick-walled stainless steel welded pipes
- Common in automated or semi-automated production
Applications:
- Heat exchangers
- Industrial pressure piping
- Marine and aerospace structural components
6.SAW Pipes (Submerged Arc Welding)
SAW (Submerged Arc Welding) involves forming an arc beneath a protective flux layer, shielding the weld from contamination and enabling deep penetration welds.
Key Features:
- High deposition rates and productivity
- Ideal for manufacturing large-diameter, thick-walled stainless steel welded pipes
- Suitable for longitudinal or spiral welds
Key Applications:
- Oil and gas transportation pipelines
- Water transmission systems
- Offshore and heavy structural piping
