Flux Cored Arc Welding With Ceramic Backing Tape
The typical shipyard criterion for structural welders is, understanding just how to use ceramic backing tape. Every human resource person will likely ask that question. It's not difficult to weld using ceramic backing tape. It is very similar to doing an open root weld; however, at the same time a lot easier! The fact is ceramic backing tape for FCAW is a crutch for a less experienced welder. I do have to admit this sort of backing on a weld joint creates origin penetration that is also best.
Below is the trick to welding a joint with this kind of backing. The angle of the FCAW take care of needs to be dragged or relocated backhand. The electrode needs to push the puddle deep in to the support tape best flux cored wire. Remember, you are loading a ceramic mold. If you are welding vertical up, the angle of the electrode requires to be pointed down! Yeah, I know it appears incorrect. However, that is what works.
When it pertains to welding strategy, it is a slow-moving side to side activity. The main point is to begin the pool on the side of the bevel and also permit the metal to begin filling up the joint. Once both sides of the bevel are merged, the electrode must never leave the puddle. Or else the cord will shed its arc, the electrode will certainly strike the ceramic support tape, and also pushing it off of the joint.
Something I found out with this type of a joint is that you can walk the mug. Walking the mug is not just for TIG welding. You begin by leaning the cone on the bevel after that you merely direct the electrode to the side of the bevel as well as struck the trigger. One the puddle is established you twist the cone till the electrode walks to the opposite side of the bevel. You just keep repeating this till you prepare to quit !
