Tweet. #2. 11-20-2009, 02:30 PM. I don't usually grind my welds. Either don't lay a bead on inside corners or run a bead and leave it alone. If you really have to get in there try a file, or a grinder with a narrow cut off wheel. Either of those will take a while but a wire brush will take forever. Comment.

The Fillet weld is used to create lap joints, corner, and T joints. This weld has a close to triangular cross-section similar to what its symbol looks like. But keep in mind that it's shape can also deviate from the right triangular or isosceles triangle.
Getting Around Corner Welds. Corner welds can be very awkward to finish. Highly compressed fleece disks, available in a variety of grits, are made specifically for fillet and corner welds and provide a high level of abrasion and a long service life. ... 80 grit will be enough to grind down the weld and finish the surface in one step.

The configuration you call a "corner joint" is a fillet weld. On your first bead in a fillet weld work on keeping your puddle centered in the corner or slightly up on the vertical face. You didn't say what thicknesses of steel you are trying to join. Thin gage material (1/32" to 1/1/6") can be a bit trickier than material 1/8" and thicker.
(if the outside corner weld is done correctly, fully welding the inside corner is just wasted filler) Practice the outside corner weld on some scrap pieces. You should be able to sand the corner to a nice radius with 36-grit on your 4-1/2" grinder, then finish it with 80-grit ... As for grinding welds, Everyone covered it already.
The first one is the corner weld without any grinding. It is difficult to achieve this in any other way than to deposit a full sized weld. The second is a weld that had the toes ground, and the weld smoothed. While it is in fact full sized, it will tend to look very much like the third sketch, which is an undersized weld that has the unfused ...
Groove welds shall be made with minimum face reinforcement unless otherwise specified. In the case of butt and corner joints, face reinforcement shall not exceed 1/8 in. [3 mm] in height.

Blending the weld to the parent material without overgrinding. Small work areas where a small angle grinder is the tool of choice. Coated abrasive flap discs. Product life and cut rate combination important. Conformability to the weld to blend into the parent material where grinding on either side of the weld is allowable
Welding, by design, is meant to join two pieces of metal in a permanent bond that, in many cases, is stronger than the two pieces of metal the weld joins. Breaking a weld without a grinder poses a lot of challenges. Managing to break a weld without a grinder can be arduous and may ultimately render the two pieces of metal unusable.
Mar 16, 2010. #9. I find you can get pretty good results on 90º joints with a light tickle of a flap disc. Also, and it's a bit tricky to tell from the pics, but it looks like you've set the join up so that you're welding into the corner. You could try setting it up so that you're doing more of a butt joint.
"This allows the operator to grind down a weld, then smooth out the corners, get into tight areas, and even get inside the pipe if he needs to," Wainwright said. The flexible shaft also can work with an ordinary bench grinder, as long as it has a standard 5⁄8-11 arbor.

What is the best way to grind down an inside corner weld? (I mean for a finish piece) I've been using an angle grinder with a grinding wheel on its edge, but it seems like a lot of work and inaccurate. I'm welding 1/4″ plate steel together that has a 9″ seem. I have quite a few inside corners to go and would like a fast way to finish ...
Depending on your circumstance, decide whether you need to weld to fill the gap, or grind the open tube end so that they align with or match the curved corners. Instead of attempting to fill large gaps in a corner, it is better to recut the pieces at a 45 degrees angle that will form a 90-degree angle.
Grinding the weld bead smooth makes for a seamless, finished appearance. To do that, we started with a regular disc on an angle grinder and removed the bulk of the excess material, creating an overall curved shape for the corner in the …
Grinding off a large amount of material makes the area hot and then wavy. You should be able to get your welds to the point where they only need a quick blast with 80 or 120 grit on a flap disc to flatten. Then finish with a rubber backed 180 grit. Dont use a grinding wheel on sheet metal.
Use a standard metal grinding disc to smooth an inside corner. Attach a stiff, metal grinding disc to your angle grinder to work in tight interior corners. Hold the grinder so the edge of the disc is at an angle to the corner weld. Work in short movements to smooth the weld. Make sure to use a disc that's specifically made for grinding metal. ...

Is miter joint in welding - butt joint or corner joint ? My example includes 45 degrees miter (90 degrees) angle on two SHS (Square Hollow Sections) - 50x50x3 [mm] Working with EN/ISO norms regarding welding and joint preparation. My opinion is that horizontal welds are butt welds and vertical corner welds (fillet) - Just my opinion.
While grinding, make sure you keep the work-piece safely rested on the guard. You will probably have to re-clamp your locking pliers once or twice in order to effectively grind each corner. If you welded the edges correctly, each corner should look like a seamless transition on each side and should be free of any holes or cracks.
Posts: 78. If it is a butt weld or outside corner weld, I'd use those grinding pads with a rubber disc behind it. They do it really fast and are a lot cheaper than flap discs. You can get them in really course grits and the lowest one does the work extremely fast. I never ever use deburring wheels, they leave a way to rough surface.

If a part will eventually be prepped for paint, you may use a large-grit grinding disc to knock down the weld, then a 60- or similar-grit abrasive to reduce the Ra, or the average scratch depth. The steps can be critical. Every scratch an abrasive disc places in the metal must subsequently be removed by a finer-grit media, and if you jump from ...
What tool for grinding out a weld in a corner... As per title really. Imagine you've got a box with no lid on it. What tool would you use to grind out a weld that went right into the inside corner of the box? Obviously an angle grinder won't get in there - and a drill will just slip about all over the place.
To grind a metal corner, hold a disc against the edge at an angle with only one edge of the disc touching the corner. Grind back and forth for a sharp corner, or at a five to ten-degree angle for a rounded one. Safety First. There are a lot of things that can go wrong if you don't practice good safety techniques.
From - Artist Kevin Caron offers tips and tricks for grinding welds in tight locations ....PLEASE NOTE! THE CORRECT SITE FOR BUYING...
None of these tools would allow you to grind in a veeeery tight place. Go to your local welding supply store and ask for the carbide bits. They're about $18 each. You could even grind inside a 1/4" hole if you had the urge. They're the only tool I'd use to remove a bead such as you've shown in the pic without worrying about bitting the surround ...
