Why Weld Cameras are Essential when Welding Large Pipe

Large Pipe Fabrication

Welding large pipes using either Submerged Arc or Open Arc welding processes may pose a number of problems, such as:

  • poor alignment of torch to seam
  • improper levels or placement of shielding gas or flux
  • improper joint preparation
  • jammed wire feeders
  • wrong welding power levels

to name just a few.

 In order to avoid these problems and ensure the highest possible quality, welding processes must be monitored closely.  When automated welding processes were first introduced, fabricators stationed an operator in a chair atop a welding machine, such as a column and boom welder, to visually monitor the welding process directly.  Surprisingly, this is still a widely used approach to weld monitoring!

An empty chair waiting for the operator….

Even today, there are fabricators who are unfamiliar with automated inspection process and are forced to place an operator on a chair high above the welded pipe to monitor the welding process.  This is a health and safety problem waiting to happen!  Not only does the operator face fume inhalation, they risk injury from moving equipment, inadequate protection and dangerous heights.

Can you see the Operator monitoring the process?

In addition to the safety concerns, work breaks are a major drain on productivity.  Just think of the production time lost while moving the gantry robot or hoisting equipment down so that the operator can safely exit the equipment at ground level, not to mention the idle time until the operator returns to their position.

A Better Solution

The better solution is to use a remote monitoring weld camera installed at the weld head that can be viewed from as far as 100 m away.  Operators are on the production floor, removed from the welding process but still able to see all the details of a welding process.   Watch the video below, created by LJ Welding in Edmonton, Alberta, Canada, for an excellent demonstration of how weld cameras are being used in the field:

Marketing your Welding Products with Weld Videos

Posted by Cameron Serles on Tuesday, February 28, 2017 @ 04:30 AM

Why should your customers buy from you rather than your competitors?

It can be easy to take for granted that your processes are more efficient, your production environment healthier and your service levels higher than your competitors.  However, if your customers don’t recognize your advantages, you could be missing out on an opportunity to gain a competitive edge - and increase your sales.

How do you communicate with your customers in order to stand out from the crowd?  If you make a product for the welding industry, a novel approach is to use the Xiris Weld camera to produce stunning videos of your unique process to clearly demonstrate what your product does.  Using the Xiris Weld camera, you can acquire high contrast, clear images that show off the processes that make your product special.

A Clear Image of the Welding Process Demonstrates your Product Quality

Using a Xiris Weld camera to image your product’s welding process is an inexpensive and quick way to help your customers visualize the benefits you are offering them.  Recorded video is easily generated, eliminating the need for expensive production facilities, animation or computer graphics.

Imagine for example that you have developed a new or improved magnetic oscillator technique and you want to show it to the world!  What better way than to record a video showing the problem to be solved and the process resulting from the application of your product. 

One example of this is the Spin Arc welding process.  Once thought to be obsolete, spin arc welding is making a comeback that needs to be explained to prospective customers.  By presenting a video of the process, customers can clearly see the benefits of high deposition rates, better side wall penetration and the elimination of the need for torch oscillation, as seen in the sequence of images below:

How to Reduce Customer Returns from your Tube Mill

Posted by Cameron Serles on Tuesday, February 14, 2017 @ 04:00 AM

When a customer refuses to accept a shipment because of a quality problem, the cost escalates as soon as the tube leaves the plant. The cost of customer returns includes all product that gets returned from, rejected by or credited to a customer. It also includes the expense of sorting, investigations, meetings, reporting, shipping, handling and containment.  The tube producer may have to rework the product until it meets customer expectations, scrap it or, worse, send a team to the customer’s site to inspect each piece manually.  By adding weld inspection into a tube production line, the rate of defect detection will be higher as the weld inspection system will be able to detect, at a high level of accuracy, defects that are not easily detected by NDT equipment or manual operators.  With higher defect detection rates, better quality product will be shipped, ultimately reducing customer returns.

How to Find Defects Sooner and Reduce Scrap on a Tube Mill

Posted by Cameron Serles on Wednesday, December 21, 2016 @ 05:00 AM

In a tube mill, production scrap can come from just about anywhere: tooling wear, bad material inputs, out-of-maintenance equipment or a process that is out of control.  Regardless of where it comes from, the creation of scrap costs tube fabricators a lot of money and time.  Since raw material accounts for the majority of the cost to make a tube, reducing the scrap rate by even a fraction of 1% can provide substantial savings to the tube fabricator.

Typical Scrap Generated from a Tube Mill

Traditionally, defects are found on a tube mill at the end of the production line by existing NDT equipment or alert operators.  By placing an automatic weld inspection system right after the weld box, defects or weld zone variations can be detected earlier in the production process and can be removed from production prior to further value being added to defective products.  By detecting the defects automatically right after the weld box and not manually by an operator or inspector at the end of the line after cutting or bundling, a complete length of tube can be saved by responding faster to the out-of-control process.

The result is material savings of scrap tube because the process can be brought in control sooner, avoiding producing extra lengths of defective tube.

Checking Tube Welds Before and After Scarfing

Posted by Cameron Serles on Wednesday, December 07, 2016 @ 10:01 AM

Animation_small.gif

The process of tube welding requires several variables to be in check for efficient and stable production and to meet the quality demands of the industry.  Mill dynamics, from setup to production, have an impact on the stability of these variables.  Measuring and monitoring these variables is the first step in controlling them and improving weld quality for tube fabricators.

In response, tube fabricators employ laser based weld inspection systems to monitor a variety of geometrical features around the weld area of the tube and to provide early warning of quality issues related to the welding and forming process.  Traditionally placed right after the weld box on a tube mill, where the majority of tube forming and weld bead measurements can be made, such systems provide the operator with an early warning of weld related process variations that could lead to quality defects.  

While most tube mill customers use the system right after the weld box where the most as-weld related information is available, some fabricators use it after scarfing to check for quality issues related to the scarfing process: does the scarfing tool cut too deeply, or not enough?  Is the tool damaged?  Is the scarf cut a consistent amount?  All these questions can be addressed by installing a weld system after scarfing.

Now, Xiris has developed a double head laser based weld inspection system that allows for one head to be placed immediately after the weld box and one head immediately after scarfing.  In this way, tube fabricators can monitor their tube production before scarfing for weld related defects; and after scarfing for potential scarf related issues.

Reducing Tube Mill Downtime with Weld Inspection

Posted by Cameron Serles on Wednesday, November 23, 2016 @ 03:00 AM

Tube mills require a large capital investment that often gets amortized over several years.  Even assuming that a mill is written down over an extended period, such as 10 years, the total cost of running a mill can be substantial when including the hourly amortized cost of the mill, the operating costs and related personnel costs.  Not surprisingly, minimizing mill downtime is always a priority for tube producers.  When a tube mill stops for planned events (such as product change overs, mill qualification, planned maintenance), or unplanned events (such as equipment failures, material input problems, shortage of operators, unscheduled maintenance), production stops.  For most tube fabricators, downtime is the single largest source of lost production time.  While there could be many reasons for a mill’s downtime, focusing attention on the constraints of the mill to ensure optimal use of resources is the most direct route to improved productivity.  When manufacturing processes get out of control on a tube mill, common trial and error solutions typically prolong the time needed to correct the process.  The result is high wastage and repair costs.

In contrast, by implementing automated tools such as an automatic weld inspection system, mill downtime can be reduced by improving the use of resources needed to keep the process in control.  With this equipment, tube fabricators can get a better and more advanced warning of process issues that are moving out of tolerance so that the mill does not have to be shut down to fix major tooling or welding issues.
