i will be needing to rebuild some of this and it will be under heavy traffic and high impact.could i use a 7018 or 316l for this?if not can anyone suggest a rod?

If this weldment will be under high traffic you really should use the proper electrode. E7018 or any austenitic stainless is a really bad choice
The proper choice would be an austenitic manganese such as Stoody Dynamang or Lincoln Manget ( or equivalent in wire form )
The best choice would be a premium austentic chromium manganese . Most typically these are "15CrMn" such as Wearshield 15CrMn . These products work harden much faster and yeild better impact resistance
If you are welding on super extreme impacts such as railway frogs or crossing diamonds that get the crap pounded out of them the next step "better" is a higher Mn content austentic manganese such as Frogmang ( Lincoln ) , Track Mang ( Stoody ) etc
BTW the most deadly welding fumes you could possible encounter is hardfacing austentic manganese . Use a respirator and fume evac system

thanks trg-42.i was looking at some sodel products just then with some friends and they make a 2024 plus and a 325.these both sound like good rods for the job but which one do you think would be better?you can view their product sheet at their website.thanks

Sodel put so little information on their products in print / internet that its darn near impossible to assertain what the product is used for
AS far as can tell the Sodel 2024 is a chromium carbide hardfacing, which is not a good choice at all for what you are doing. I am guessing this from that fact that Sodel claims "excellent" abrasion but only good impact
As far as the Sodel 325 I have no clue since there is no info on this in my library or the internet
You really should be looking at brands that are not afraid to publish the chemical composition of their hardfacing electrode, such as Stoody, McKay, Lincoln, ESAB, Eutectic, Rankin, Hobart etc
What you are looking for is anything that is at least 15% Mn for severe impact applications
