Advanced Welding Solutions for Steel Drum Manufacturing
Steel drums, commonly used for storing oil, chemicals, and industrial liquids, require reliable welding to ensure leak-proof performance and durability. The production process involves several critical welding stages, each affecting the drum’s integrity and service life. At Longterm Weld, our solutions for steel drum manufacturing include longitudinal seam welding, circumferential seam welding, and spot welding machines designed for efficiency, strength, and global standard compliance.
The body of a drum begins with a rolled steel sheet, which must be welded along its longitudinal seam. Traditional resistance welding methods are prone to uneven penetration, leading to weak lines. Longterm’s automatic seam welding machines use precision-controlled resistance welding and submerged arc welding (SAW) for thicker drums. This produces uniform weld beads, stronger joints, and higher leak resistance, reducing the need for costly rework.
Once the body is formed, circumferential welding machines are used to attach the top and bottom lids. In this stage, maintaining perfect circularity and airtightness is critical. Our circumferential seam welders use rotary clamping fixtures that ensure precise alignment, while adaptive current control prevents overheating or incomplete fusion. Compared to manual welding, this automated process improves both speed and reliability, ensuring drums pass hydrostatic and drop tests without failure.
Additional components such as reinforcing rings and bungs are attached using spot welding or MIG welding systems. Longterm’s equipment integrates automated feeding, enabling manufacturers to increase throughput while minimizing operator involvement. By combining speed with precision, our welding solutions ensure every steel drum is capable of withstanding rough handling during transport and storage, without risk of leaks or deformation.
Manufacturers who adopt Longterm’s drum welding solutions benefit from reduced production costs, fewer rejects, and improved compliance with international standards such as UN packaging certification. With strong seams and consistent quality, our machines enable producers to meet the growing global demand for reliable oil and chemical packaging.
