Etching welds.

As the old race drivers will tell you.."there is no substitute for cubic inches"...

My experience is in racing, there is no substitute for cubic dollars! :thumbsup:

The 6010 weld is dug in pretty good. I ran that with my Everlast PowerArc 300.

You Like that PA 300 don't ya . I have the baby brother to it a PA 140. It runs 1/8" 6011, 7014 and 7018 nice. I've been wanting to try some 5/32 with it but never got around to it. Super good welders for the price.

Oh yeah! She is a sweet machine:cool2:. I really like it with 6010. I think my Power Arc 200 has the edge with 7018 tho. Last picture is 7018 with the PA-300.

I redid the fillet welds done with 6010, and 7018 this morning with the phosphoric acid.
First picture is the 6010 weld with the acid still on.
Second pictures is the 6010 weld with the acid wiped off.
Third pictures is the 7018 weld with the acid still on.
Forth picture is the 7018 weld with the acid wiped off.

Very Interesting. Better than a bend test.

I don't know if it is "better" but it certainly gives a different piece of information. I think both have value in evaluation of a weld.

How are you cutting for these views? It almost looks like you cross cut them then put the flap wheel to it?

Used a port-a-band to cut them. Then an 80-grit sanding pad, 120-grit flap wheel then a 180-grit flap wheel.

Is that 3/8 metal ? You would think the 6010 would burn in deeper.
