Longitudinal Seam Welding Machine Schnelldorfer LINEARWELD XL INEX 2600

Longitudinal Seam Welding Machine Schnelldorfer LINEARWELD XL INEX 2600


LINEARWELD XL INEX 2600 is a versatile and robust automatic longitudinal welding machine belonging to the XL (eXtra Large) series. This model provides a maximum seam length of up to 2620 mm and specializes in processing medium-thickness materials ranging from 0.2 mm to 3.0 mm.

The standout feature of the INEX modification is its ability to weld from both the internal and external sides of the workpiece. Designed to join cylindrical products with a minimum internal diameter of 260 mm, the XL INEX utilizes SIEMENS controls and the intelligent HMI “neXt” interface. It serves as a flexible and reliable solution for manufacturing large-scale air ducts, exhaust systems, and general mechanical engineering components.

Features and Advantages

Feature Description
INEX Versatility Unique design allows for welding from both the inside and outside of the part, significantly expanding the scope of application.
Medium Thickness Optimization Specifically tuned for high-precision welding of materials in the 0.2 mm – 3.0 mm range.
Premium Components Employs reliable SIEMENS PLC controllers and servo drives, ensuring high motion precision and long-term durability.
Industry 4.0 Ready The neXt Control system supports OPC UA, AI-assisted parameters, and Remote Access for modern factory integration.
Superior Weld Quality Delivers minimal part deformation and clean, discoloration-free seams thanks to precise clamping and advanced gas shielding.
Modular Platform Supports the integration of all common welding processes: TIG, Plasma, and MIG/MAG.

Standard Equipment

  • Control System: Siemens S7 PLC and high-performance servo drives. Includes a 7” Siemens Comfort Panel with the HMI "neXt" interface.
