Xiris' WeldInspection System Helps Identify the Root Cause of Variations in Tube Production

Many applications require tube producers to identify and document their tubes by batch, date and sometimes even time stamp for trace-ability. If a tube segment fails at a sub process or worse at the end user, a detailed analysis and root cause investigation follows.

Audit Log Files from Xiris' WeldInspection System

When the original tube production date and time information is available, a helpful tool to identify anomalies is to review the audit log files generated on Xiris’ WeldInspection system.The audit log files are date and time stamped and easily accessible to look for any weld related geometries that may have deviated for a time period during the production run.

Variations may be a change in bead shape/size that can be an indicator of squeeze pressure or weld heat change. With the WeldInspection system monitoring multiple geometrical conditions such as mismatch, bead height, width and potential freeze line, much information can be gained by reviewing the log files and identifying a potential root cause. Additionally if a particular condition has been identified as the potential cause, the audit logs can be utilized to determine for how long that condition existed therefore helping reduce the volume of product that might be quarantined for further evaluation.

Post Scarf Inspection on Tube and Pipe Mills

Posted by Cameron Serles on Tuesday, June 30, 2015 @ 09:54 AM

Scarfing is a process of removing excess weld bead on a pipe or tube to create a desired shape.  It is done by planing longitudinally welded tubes or pipes right after the welding process.  If it is done perfectly, the resulting profile will match the ideal shape of the parent material.  However, if the scarf tool is set to plane too much material, or not enough, the resulting profile could appear too deep or leave a weld bead above the parent material.

Detecting if the scarf tool is properly adjusted is a difficult task to do on a continuous basis.  In particular, some thick walled tube and pipe mills make precision end products using multiple scarf cuts using scarfing tools operating sequentially.  If not correctly adjusted, the tube or pipe could end up with an incorrect profile shapes where the scarf occurred.  A way to make sure that the right amount of material is removed from the welded tube is important.  If placed after the scarfing process on a tube mill, the Xiris WI-2000p can measure the scarf width and bead height left behind after a scarfing process to provide quality control of the scarfing process itself.

In the above image taken from a WI-2000p system, a laser profile is shown of a welded tube, post scarf.  The area of the scarfing does not reflect the laser line as well, so the scarfed area can be easily detected and measured.  As the scarf cuts deeper into the material, the scarf width will increase, as it cuts shallower, the scarf width will decrease.

Conclusion

Measuring the scarf area of a tube or pipe with a device such as the WI-2000p Weld inspection system from Xiris is a quality control tool to ensure that the scarfing process has been set properly and not cutting too little or too much of the parent material away.
