Minimum Rolling Diameter and Springback for Rolled Steel Cylinders

Minimum rolling diameter is one of the most misunderstood figures in cylindrical sheet metal fabrication. A machine specification may list a reference diameter, but that number does not automatically apply to every plate, every thickness, every material grade, or every finished-part tolerance. A cylinder made from 0.8 mm cold-rolled steel behaves very differently from one

Working Principle of a Longitudinal Seam Welding System for Tanks and Ducts

A longitudinal seam welding system is more than a welding torch moving along a straight line. It combines mechanical positioning, precise motion control, stable heat input and intelligent process management to produce consistent, low-deformation welds on cylinders, flat plates and open-ended square boxes. For engineers who need to understand the inner logic of the equipment,

How to Choose a Longitudinal Seam Welding Machine for Tanks and Ducts

When fabricating air tanks, gas cylinders, stainless chimneys or HVAC ducts, the quality of the longitudinal seam often determines the overall performance of the product. A poorly selected welding system can lead to excessive deformation, inconsistent weld appearance, or frequent rework, which directly affects delivery time and cost. For engineers and procurement teams in the
