Seam Welding Machine Market Report 2026

The seam welding machine market size has grown steadily in recent years. It will grow from $1.4 billion in 2025 to $1.46 billion in 2026 at a compound annual growth rate (CAGR) of 4%. The growth in the historic period can be attributed to growth in automotive body manufacturing, expansion of industrial fabrication activities, rising demand for leakproof metal joints, increased adoption of resistance welding, growth in construction equipment manufacturing.

The seam welding machine market size is expected to see strong growth in the next few years. It will grow to $1.78 billion in 2030 at a compound annual growth rate (CAGR) of 5.1%. The growth in the forecast period can be attributed to electric vehicle body production growth, rising automation in metal fabrication, increased oil and gas pipeline investments, demand for lightweight metal assemblies, expansion of smart manufacturing facilities. Major trends in the forecast period include rising adoption of automatic seam welding machines, growing demand for high speed continuous welding, increased use of precision controlled welding wheels, higher focus on leakproof and consistent weld quality, expansion of seam welding in lightweight materials.

The increasing demand for aircraft is anticipated to support the expansion of the seam welding machine market in the coming years. An aircraft is a vehicle engineered for air travel and capable of remaining airborne through its interaction with the air. Seam welding machines play a crucial role in aircraft manufacturing, where they are used to join metal sheets, assemble aircraft panels, and produce fuel tanks. For example, in January 2025, Airports Council International (ACI), a Canada-based association of airport authorities, reported that global passenger traffic is projected to exceed pre-pandemic levels, reaching 9.5 billion in 2024, more than 12 billion by 2030, and doubling to 19.5 billion by 2042 compared to 2024. Therefore, the rising demand for aircraft is fueling the growth of the seam welding machine market.

Major companies in the seam welding machine market are prioritizing technological advancements such as automated straight seam and circumferential (girth) seam welding machines with servo drive control and laser-guided seam tracking. These innovations aim to meet growing requirements for enhanced productivity, precision, reduced manual labor, and consistent weld quality, particularly in industries such as pressure vessels, pipelines, shipbuilding, and heavy-duty structures. For instance, in April 2025, Jinan Haoyu Automation System Co., Ltd., a China-based welding automation manufacturer, presented its new automatic straight seam and circumferential seam welding machines at EXPO IEC 2025 in Astana. The straight seam machine features a servo-driven welding carriage equipped with a laser-based seam tracking system to maintain exact alignment and minimize straightness errors, making it ideal for long welds in pressure vessels or steel structures. The circumferential seam welder includes a high-precision rotating mechanism that enables 360° girth welding for pipes and cylinders, supporting both inner and outer girth welds for pipe diameters ranging from approximately 50 mm to 3000 mm. Unlike manual or semi-automatic welders, where alignment and consistency rely heavily on operator skill, these automated systems provide significantly higher throughput, lower defect rates, and more uniform quality for large-scale fabrication tasks. This trend reflects the growing demand from the energy, shipbuilding, infrastructure, and industrial fabrication sectors for high-precision automated seam welding equipment.

In February 2025, Miller Electric Mfg. LLC, a US-based provider of arc welding products and equipment, formed a partnership with Novarc Technologies Inc. to merge Miller’s expertise in welding equipment with Novarc’s AI-driven robotics. This collaboration aims to introduce next-generation automated welding solutions designed to improve productivity, quality, and automation across fabrication, shipbuilding, heavy equipment, and construction industries. Novarc Technologies Inc. is a Canada-based full-stack AI robotics company specializing in developing automated welding systems for complex welding applications.
