Product Overview
A resistance seam welder is used when a continuous, stable, and sealed weld seam is required. Instead of using single welding spots, the machine forms overlapping weld nuggets through rotating electrode wheels. This makes it suitable for shock absorber cylinder welding and other tubular metal parts that require reliable seam strength and good sealing performance.
Haifei resistance seam welding machines can be configured for semi-automatic or fully automatic production. Depending on the customer's process, the system can include customized fixtures, automatic clamping, electrode wheel control, water cooling, welding parameter storage, and production line integration.
Key Features of HAIFEI Resistance Seam Welder
Stable Continuous
Seam Welding
The machine produces continuous weld seams through controlled electrode wheel rotation and stable welding current output. It helps reduce common welding problems such as uneven seams, insufficient fusion, overheating, and poor sealing.
01
Intelligent Welding Parameter Control
The welding system can control key process parameters such as welding current, electrode pressure, welding speed, welding time, and cooling conditions. These parameters directly affect weld nugget overlap, seam appearance, and welding strength.
02
Custom Fixture for
Cylinder Welding
For cylindrical workpieces, fixture stability has a direct impact on weld straightness and seam consistency. Haifei can design custom fixtures according to cylinder diameter, length, welding position, loading direction, and production takt time.
03
Water-Cooled Electrode Wheel System
During continuous seam welding, the electrode wheel generates heat after long-time operation. A water-cooled electrode system helps control electrode temperature, reduce wear, and maintain welding stability during batch production.
04
Semi-Automatic or Automatic Production Options
Haifei can provide different automation levels according to customer needs. The machine can be configured for manual loading, semi-automatic clamping and welding, or automatic line integration.
05
Applications of Resistance Seam Welders
Shock Absorber Cylinder Seam Welding
This is one of the main applications of Haifei resistance seam welders. The machine can be used for continuous longitudinal seam welding of shock absorber cylinders. It helps maintain straight weld seams, stable penetration, and consistent sealing quality.
Automotive Suspension Component Welding
In automotive parts manufacturing, many metal components require stable welding quality and repeatable production accuracy. Resistance seam welding can be used for selected tubular or shell-type suspension components where continuous welding is required.
Hydraulic and Pneumatic Cylinder Production
For some hydraulic and pneumatic cylinder-related components, continuous seam welding may be required to meet strength and sealing requirements. Haifei can evaluate the workpiece drawing, material type, wall thickness, and sealing standard before recommending a suitable welding process.
Custom Metal Tubular
Parts
Haifei resistance seam welders can also be used for customized metal tubular parts, sealed shells, and cylindrical components. The machine configuration can be adjusted according to the shape, size, welding position, and production method of the customer's workpiece.
