Introduction

Prior to automatic forming or processing of longitudinally welded tubes the long seam detection and
positioning to a predetermined position is a preventive measure the motive being a fault free
product.
The SND40 is specially designed for this task, and provides:
• High flexibility with regard to material, tube processing condition and machine integration
• Self-monitoring of weld seam detection with superior evaluation methods
• Monitoring of the sensor and of the tubular drive
• Easy positioning with adjustable set angle
• Convenient operation and control interfaces
The highest flexibility of SND40 is achieved using magnetic flux leakage and eddy current
methods. In addition, special signal filters and a wide range of sensor models have been developed
which lead even in challenging cases to success.
Prior to the implementation of a station for weld seam detection the following steps are required,
with which Roland Electronic can provide assistance:
• Feasibility studies on representative samples in the Roland laboratory
• Review of the requirements of cycle time, positioning accuracy and process reliability
• Conception of the weld seam detection station
Once a station is built, Roland Electronic can offer support during commissioning of the SND40.
In addition, services for setting up new types of tubes, maintenance inspections, sample tests and
training courses for operators, maintenance personnel and plant engineers are offered.
The Weld Seam Detection System SND40 typically consists of:

The control unit and the weld seam sensors are available in different versions. Which version fits
the particular weld seam detection is determined in advance by the feasibility study in the
laboratory. Only the decision whether I/O or fieldbus interface implemented needs to be taken by
the customer.
Note:
Specify the number of the application report when ordering the system and the
required settings will be made before shipping. For each required type of tube, i.e. any
wall thickness, diameter and type of material a separate data record will be available.
