How-To Weld Elbow Joints Easily: The Welding Positioner Elbow Jig


Introducing The Elbow Jig

SITUATION

Pipe fabrication facilities have always needed to weld elbows for long pipe runs that change directions but it has always been a cumbersome, challenging and often dangerous process. Many facilities have identified this as an opportunity for improvement but until now, did not have a viable solution for the problem. It has resulted in a variety of make-shift, temporary solutions for a long-standing welding operation often done hundreds of times per year. 

 

PROBLEM 

elbow jig mistakeWelding elbow joints are time consuming and difficult because of the awkward shape they present, the weight they carry and the degree that they bend. Without a proper brace securely fastened to the elbow and pipe welding positioner, the job must be done manually. 

  • Safety Issues: By fabricating a make-shift elbow brace that hasn't been destructive tested or designed by APEGA certified engineers, this puts welders in danger and the company liable for injury or death.
  • Time Consuming: Manually welding elbows is time intensive and lost welder productivity is preventable waste.
  • Expensive: If this low variability / high volume process isn't automated it's an inefficiency that is making pipe yards less competitive because they are less profitable.

 

 

SOLUTION

 LJ responded by creating the elbow jig. Here's how it works:

Step 1: Set Your Gripper To The Pipe Welding Positioner's Chuck Face
