Welding is a critical part of stainless steel pipe manufacturing. This article explores the various welding techniques used to produce welded stainless steel pipes and the best practices for achieving high-quality, durable welds.

The submerged arc welding process is ideal for important applications in pipelines, pressure vessels and tanks, rail manufacturing and major construction. It has the simplest single wire form, twin wire structure, tandem twin wire structure and multi-wire structure.

Spiral steel pipe is made of strip steel coil as raw material, extruded at room temperature, bent into a spiral shape, and welded with inner and outer seams by automatic double-wire double-sided submerged arc welding process. The raw materials are strip steel coil, welding wire, and flux.

What is the influence of metal elements in the production of spiral pipe? Next we will give you an introduction.

The comparative study of different forming methods shows that the edge forming effect of single-radius and double-radius forming method is poor, while the forming method with three-radius W shape is better.

Galvanized steel is generally in the low carbon steel outside a layer of zinc, galvanized layer is generally 20um thick. The melting point of zinc is at 419°C, and the boiling point is about 908°C.

Adopt the power source with vertical external characteristics, and use the positive polarity (welding wire connected to the negative pole) when DC.

LSAW steel pipe is a kind of welded steel pipe. It refers to the steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe.

Nowadays, many spiral pipe manufacturers through the production and processing of spiral pipe in the surface did not meet the standard requirements, but there are still successive spiral pipe. Here are some spiral pipe manufacturers to understand some of the requirements for the surface of the pipe.

Straight seam welded pipe production process is simple, high production efficiency, low cost, faster development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe, and it can produce welded pipe with larger pipe diameter from narrower billet, and it can also produce welded pipe with different pipe diameter from the same width of billet. However, compared with the same length of straight seam pipe, the length of welded seam increases by 30-100%, and the production speed is lower.
