Cut n turn welding question , old oil in cut

[James92toy]

Getting ready to weld up my cut and turn. Theres seems to be some old oil between the housing and the knuckle ball sleeve that weeped out just a little. Whats everyone doing to clean this up so it docent contaminate the weld? Should i try to pull the ball off to clean or spray some brake cleaner in the cut and blow it back in the housing with some air ?

Not sure if it matters , but i was going to weld it with an arc welder and some 1/8 6011 rods.

You could also use a torch to heat it up and burn out the oil contaminants.

I only have a hand torch with map gas . Don't know anyone with a oxy/acc torch.

I guess i could try map gas.

Mapp gas is more than hot enough to burn off any contamination. John

Probably not.

Yea use your hand torch. I use mine for cleaning surfaces before welding all the time. Great alternative to firing up the oxy/acetylene. Plus it gets more than hot enough to bun off oil, dirt, rust, etc.

Use a wire brush while heating the area to get it super clean.

I pulled the ball of mine... not hard to markout... and plus your rotating it anyways...

Yeah, DO NOT use brake cleaner!!! I must have gotten lucky, because I'm sure I did this in the past. Scary stuff, for sure.

You are not trying to weld to the inner sleeve itself, you are welding the outer housing. As long as you clean the weld surfaces real well, the oil shouldn't be an issue.

I would get my turn angles aligned, then bevel the two pieces for good penetration and clean them up with carb cleaner and burn 'em in.

Am I overlooking something here? It doesn't seem like oil below the weld surface would be a factor. However, I am far from an authority on the science of welding.

Probably not.

I ended up hearing it up with map gas and then welding it up . No problems .

Cool. Good job.
