Vertical Stick CJP with Back Gouge - Full Pen

SMAW | Stick

Back gouging is one of many ways to perform a complete joint penetration weld, also referred to as a full pen weld. In this application, two plates are welded from one side, there is usually no gap between the plates, and a backing strip is not needed.

 The front of the weldment is welded out fully and then the back side of the plate is then cut or gouged to the depth of weld metal. In this episode, we opted to try out the new gouging head on the Hypertherm PowerMax 105. Plasma gouging is an extremely fast way to perform gouging and is very precise in the hands of a seasoned operator. Gouging makes quick work of the task as opposed to grinding the seam open. It also requires very little clean up. The dross can be removed quickly with a chipping hammer and then the carbon deposits can be cleaned up with a few passes of a grinder, leaving the joint ready to be filled and capped. 

If you have not tried the new gouging torch from Hypertherm, I highly recommend giving it a try. Plasma gouging is much faster than using carbon arc rods and easier to use in my opinion. I hope you enjoy the video and try the techniques out for yourself. Let us know your thought in the comment section below. Until next time Make Every Weld Better Than Your Last!
