How Weld Inspection Helps Tube Producers Meet Weight Reduction for Automotive Sector

Posted by Emily Blackborow on Tuesday, May 14, 2019 @ 01:00 PM

The Automotive Sector is constantly trying to reduce the weight of cars. Part of that effort is to approach their suppliers to see what they can do to reduce the weight of their components. Fabricators of tubes for the automotive sector are constantly being asked to meet more difficult weight limitations of their tubes.   

In order to achieve the desired weight reduction of a tube, tube fabricators need to use:

  • Lighter materials;
  • Thinner Wall Thicknesses; and
  • Higher Yield strength materials.

These are only possible if tighter manufacturing specifications and process tolerances are established.

Tubes fabricated from higher yield strength material are more susceptible to mismatch during fabrication. Traditionally; fabricators used a common practice of allowing mismatch on a longitudinal welded tubes of up to 5% of the wall thickness. 5% becomes a very small number very quickly when wall thickness is reduced. 

Experience has shown that for higher yield strength materials a mismatch of 5% will result in a higher weld split failure. In these applications tube producers need to maintain a mismatch tolerance in the 2% to 3% range, well below common practice on milder materials. These tight tolerances make it difficult for mill operators to see or detect using traditional means of looking at the scarf material, the finger nail scratch without stopping the mill interrupting production.

High resolution geometrical measurements are required in the weld zone making this an ideal application for laser based technologies such as Xiris’ Weld Inspection Solutions. The WI2000 or WI3000 makes continuous measurements providing the operator with a clear visual of the weld zone form process while also being able to set tolerance limits to alarm when an unexpected variation occurs.

Why Recertification of Your Inspection System is Important

Posted by Emily Blackborow on Tuesday, April 02, 2019 @ 11:00 AM

In today's modern manufacturing environment, continuous improvement is needed to stay competitive. This means equipment up-time, speed and product quality must always be optimized to increase yield and profitability. Any downtime can be minimized by keeping all production and online inspection equipment well maintained and calibrated. 

Sensor HeadThe Xiris WI sensor head Recertification Program is designed to recertify WI sensors onsite at your facility by Xiris personnel with minimal interruption. This helps ensure optimal WI system performance by maximizing tube mill productivity and should be a part of your ongoing quality assurance and yearly preventive maintenance program.

Xiris Recertification Program is done by factory trained personnel and has been designed to ensure your investment in the WI2000/3000 pipe and tube inspection equipment is functioning optimally and in accordance with factory performance plans.   

Recertification takes less than 1 day onsite and we use our field certification kit to check all electronic and optical components to verify laser power is at recommended levels, camera optics are aligned and focused and within factory specifications, and that head measurement accuracy meets factory specifications.  We will also update sensor head firmware, if required, and apply a sticker with date of certification. We perform a generalized computer health check, install any software upgrades as applicable and backup system software and settings.

As a final step, Xiris will also provide you with a detailed report outlining the sensor certification and status, condition of the system and any recommendations to address potential system risks. 

NOTE: No internal adjustment can be done in the field due to laser safety requirements. Any internal repairs would have to be done at a Xiris facility under a separate quotation. 

A WI2000 or WI3000 system is a major investment that can continue to provide a significant productivity gain for your tube mill as long as it is properly maintained and recertified on a yearly basis.
