How Does the SWR Affect Weld Quality and Consistency?

 It’s time to answer one of the most commonly asked questions we get: How does the Spool Welding Robot (SWR) affect the weld quality?

Here is the short answer:

The SWR can meet the quality standards set by the pressure welding codes (such as ASME B31.1 and B31.3).

So how does the robot produce consistent quality welds you ask?

Full Control over all Welding Parameters

One major challenge with manual welding is that it is nearly impossible to change weld parameters during the weld. As any good welder knows, every time you have to stop and start again, there is a risk for an indication in the weld. This risk is instantly diminished with the SWR as it allows a junior welder to have full control over all welding parameters, and instantly change the parameters during the weld. The SWR lets you weld the joint from root to cap, increasing the overall quality and consistency of your welds. 

Ability to see how much Reinforcement is being used

With the SWR and Novarc’s Welding Vision System, the operator can see how much reinforcement is being put in to the root of the weld at all times. This removes a lot of frustration and stress on the welder and also eliminates the need for repair work, which is a costly process for shops. By pairing a junior welder to operate the SWR, fabrication shops can have defect rates lower than 1%. 

Reduces Human Error

Humans are prone to error, and manually producing repeatable and consistent high-quality welds has proven to be extremely difficult. Weld consistency typically deteriorates during an 8 hour shift as welders become tired. If your company struggles with creating consistent quality welds, then the SWR can be a major benefit. The SWR is able to control weld parameters by taking the torch out of the welders’ hands, and therefore repeatedly create high-quality welds.

What our customers have found is that with proper training and adequate welding knowledge, they have achieved nearly 100% X-Ray Quality. As you can see, the SWR allows shops to consistently produce high quality welds as it allows the operator to have full control over all welding parameters, see how much reinforcement is being used and reduces the risks of human error.
