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 process.

Our Megabrite Inside Corner Weld Blending Disc is a 3D web of resin embedded nylon thread with silicon carbine grain added. This construction allows for a cool grinding action that leaves a uniform finish. This 4-1/2″ x 1/4" x 7/8″ Unitized Type 1 2SFN Disc is often used in conjunction with our Stainless Steel Tube Finishing Kits.
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.
Groove Welding Symbols. A groove weld will be used when to parts come together in the same plane. These welds will be applied in a butt joint and may have a preparation or not before welding. This is the reason there are several types of groove welding symbols. The symbols for these grooves are nearly identical to the symbols that represent them.
It's best used at a 10-15° angle and needs to be moved slowly across the metal, using just the weight of the angle grinder for pressure. Also try NEX-3SF spec for more durability when flexibility and comfortability is less of a concern. For best results and to avoid burn use at 6000 to 7000 RPM.
Both plates have a corner cut out in a ¼ moon shape about ¾ of the plate gauge deep to form a U partway through the joined sections, as the weld symbol shows. Single J butt One plate has a square end, while the other has a corner cut out in a ¼ moon shape part way through the plate thickness, forming a mild J when joined, as you can see in ...
In this video I go over a few simple ways to deal with the dreaded inside corner weld. This weld is often the hardest to get finished to a consistent look an...
The first step would be to remove a layer from the weld bead to make it semi-flush with the base metal. The details of the processes might differ depending on the metal, type of weld, and location but broadly the process is the same. You can use a grinding wheel to get it done.
Thread: Surface grinding technique: roughing corner/finishing corner. Thread: Surface grinding technique: roughing corner/finishing corner. on peening and heating: local temperature rise during grinding can be substantial. doest this reverse the straigtening? It can, I peripherally mentioned that earlier.
Weld types in edge joint implicate welds like butt, bevel-groove, V-groove, J-groove, U-groove, edge flange, and corner-flange welds. The edge joint is also amidst the solid joints that provide large surface area clamped between the welds. An edge weld can be made attractive by using weld preps. This practice would gift a nice finish to the weld.
A fillet weld is defined in the American Welding Society (AWS) AWS A3.0 Standard Welding Terms and Definitions as "A weld of approximately triangular cross section joining two surfaces approximately at right angles to each other in a lap joint, T-joint, or corner joint." (Figure 1).
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. (See Figure 1). You first should use 80 grit to remove scratches that occur from pregrinding to ...

Double Welds In some cases, a weld cannot be made from only one side of the joint. When a weld must be made from both sides, it is known ...
Fillet Weld Grinder. Metabo's fillet weld grinder, model KNSE 12-150, might look like a right-angle grinder with an extension, but it's a little different from a right-angle grinder (see Figure 3). "You cannot mount traditional abrasive discs on this machine," said Terry Tuerk, senior product manager for Metabo.
Cold laps can occur on fillet welds or butt welds, usually as a result of a current that is too low, by using down-hand welding, the environment or by using a high welding speed. It is important to remove the entire weld by grinding it back and subsequently check to ensure that the overlap material has been removed.
(2) Edge flange welds shall be shown by the edge flange weld symbol (A, fig. 3-59). (3) Corner flange welds shall be shown by the corner flange weld symbol (B, fig. 3-59). In cases where the corner flange joint is not detailed, a break in the arrow is required to show which member is flanged (fig. 3-59). b. Dimensions of Flange Welds.
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. Metal grinding discs produce more sparks than flap discs.

Ive had this same problem. Ive been using 4.5" perfered radial grinding flap disc. They are 12$ a peice and only last about 8 feet of weld if you really go at it hard, so i use them lighlty until slightly rounded corner is shaped the finish with an angled type flap disc holding it at the right angle so it contours to the shape.
