We have given contract to the local railings constructor and they have put the railing Balusters on the floor along with clips to put glass on. I am satisfied with their work so far, only thing that is bugging me is the weird looking welding work near the clips.

This is how they look after polishing

He says his grinding wheel does not reach the corners, so he cannot smooth it out.

Is there anyway to fix this issue ?

  • is that weld just a blob? ... the picture is not very clear ... it looks like there is a gap just above the weld ... if there is a gap, then it will collect crud

  • yes its just a blob, ... I am not sure if that is the right way of doing things. Jun 2, 2020 at 7:43
  • @jsotola yes there is a gap at the top, should I ask him to weld that area also ? Jun 2, 2020 at 7:49

    Even as a non-welder, I can tell that's bad. It should be a smooth bead going all the way down, not just a random dollop.

    Railings = safety equipment = it has to be (re)done correctly.

That welding would be termed by one of my instructors as “bird droppings”...

It needs to be done properly where the weld joins and fills the 90 gap evenly and is called a fillet weld.

Get them to grind it out and do it properly. A 4” angle grinder with a new disc will get into that.

Have a look at some of the welds shown here: https://www.youtube.com/watch?v=FrS_yafue6M

    “bird droppings” so basically this question is "how do i polish a turd?"

A rule of thumb is that a good weld looks good . Your base metals look like stainless ; If it is strongly magnetic it is ferritic or martensitic. If one of those the welder must use the right fillers to avoid hard brittle welds. The weld shown does not inspire confidence.

  • I agree the base filler needs to be correct but the question is how to polish.

    That was the question but I don't think polishing will help. I think it is grind and re-weld. Jun 3, 2020 at 14:48
  • Its 304 stainless steel Jun 4, 2020 at 11:27
  • Good, 304 ( non-magnetic ) is no problem Jun 5, 2020 at 0:08
