3. Welding Following the roll forming, the edges of the tube are brought together and welded to create a continuous tubular section. Depending on the design and the material being used, various welding techniques can be applied, such as high-frequency induction welding or TIG welding. The choice of welding method greatly impacts the strength and durability of the finished product.
The welding phase is perhaps the most important part of the production line
. There are several welding techniques employed, with the most common being high-frequency electric resistance welding (ERW) and submerged arc welding (SAW).
