Why should you consider a 7-axis robot for your welding application?

Are you having problems with weld access, torch position, interference or floor space issues? If you are, our 7-axis robot can provide you with superior weld quality and ease of use that outstrips the competition. But what advantages does it provide over the more common 6-axis welding robot? Here are some of the best benefits our customers have noticed.

Why should you consider a 7-axis robot for your welding application?

  • Weld quality improvement. Because the robot can more easily bend around corners, avoid interference and adjust perfect torch position and attitude, you can get a much more consistent weld of much higher quality. This robot makes your best precision welding look like beginner work.
  • Torch position and attitude consistency. When a 6-axis robot has to rotate around more complex pieces, you'll lose consistency, while the 7-axis doesn't require repositioning that can cause this loss of quality.
  • Avoids interference with tooling and work-piece. Instead, it can bend around obstacles, whether it's tooling, the part or other obstructions. Because of this flexibility, you can avoid costly damage to the part, tools or the robot itself.
  • Savings from reduced floor-space requirement. Because the robot eliminates the need and cost for excess tables, positioners or other equipment, it takes up less floor space and creates room for new innovations in your product.
  • Flexible attitude when moving around other robots and obstructions. When a 6-axis robot moves around obstructions, the torch attitude often changes. The 7th axis allows our robot to move around these obstructions without losing torch attitude.
  • Built-in cabling delivers a slimmer robot profile. Our 7-axis robot has built-in internal cables through the arm eliminating concerns about the cables in the welding environment. The robot can also get into smaller spaces and is better able to work around tools.
  • Can eliminate the need and cost for additional positioners. The 7-axis robot works well in an environment where you need to reposition a part. It accomplishes this by taking the place of the headstock or tilt-turn table, removing the need for a positioner.

With the exception of our smallest 6-axis robotic welder, the FDH-5, we have 7-axis welding robots in the same size as our 6-axis models. If you need to upgrade your production line with improved welding operations, our 7-axis robots will help you take your production to the next level.
