        It's an add on for reinforcement. It's a new equipment and this was customer request. I have to put top cylinder guards and blade stop as well.

            It's feathering your end welds, it srpeads the stress point. You have to do that for diamond shape fishplate as well. If you have to weld a block in the middle of a boom side, you'd have to weld only on the 2 opposite sides and feather in the block and weld the side and feather out. I'ts a good habit to take.
            If you dont do this, most likely a crack will start from any corner of any welds on the face of a plate.

              Was wondering the same thing but too scared to ask

                      Is the second pic the finished weld? If so, doesnt the weld section need to be relative to material thickness?
                      It seems thick for a single pass or no bevel. It also cold be my eyes.

                        It's about a 3/8 legs for the bead and the gusset is 3/4 t-400. It's to help stabilise the front idlers.
                        I finishing installing the blade stops 3"X6"x10" with a radius on the same machine. And it only calls for 3/8" legs on the bead and 1.5 " run off ""feather to ctick that big block to the side of the blade mount frame.
                        I'll post pictures of it.

                          I've heard that a fillet on both sides only needs to total 75% of the thinner base metal thickness.

                          3/4'' x 75% = .28
                          2

                          Thats why 1/4, 5/16, and 3/8 fillet sizes are the most popular. It takes a big chunk of steel to require more than a 3/8 fillet on both sides. Especially if you figure in the effective throat.
