Circular welding applications often demand consistency, accuracy, and careful heat management across multiple weld passes. In this video, we will go over CRX Multi Pass Clocking for circular welding and how this feature can help improve weld quality, consistency, and overall appearance when working with multi pass welds.
We begin by explaining what multi pass clocking is and why it matters in automated welding applications. Rather than starting and stopping each weld pass at the same location, multi pass clocking allows us to stagger the start and stop points around the joint. Each pass is slightly rotated, similar to the movement of clock hands. This simple shift can have a meaningful impact on heat distribution and weld integrity.
Throughout the video, we will discuss the practical benefits of using multi pass clocking. We will go over how rotating weld start locations helps reduce excessive heat buildup in a single area and protects the heat affected zone. We will also explore how this approach helps minimize common weld defects and improves the visual consistency of the finished weld. By distributing weld starts and stops, we can maintain stronger fusion between passes and reduce distortion in the welded part.
We will then walk through the required software and setup considerations on a FANUC CRX platform. This includes where multi pass clocking is supported, how to enable the necessary system variable, and where to locate the clocking angle option within the weld procedure. Understanding these setup steps is key to successfully applying clocking in a production environment.
Finally, we will review the limitations and important considerations to keep in mind when using multi pass clocking. This includes geometry requirements, angular limits, and additional guidelines when using root pass memorization with offset replay.
Requirements and considerations include:
- Multi pass welding only
- Clocking range up to plus or minus 180 degrees
- No partial start points allowed
- Additional constraints when using root pass memorization
- Best practices for teaching circular paths and points
In this video, we will cover:
- What multi pass clocking is and how it works
- Key benefits for weld quality and heat management
- Software requirements and system setup
- Clocking limitations and best practices
- A visual example of multi pass clocking in action
If you work with circular welds and want to improve consistency, control heat input, and enhance final weld appearance, this overview of CRX Multi Pass Clocking will provide valuable insight and practical guidance
