Welding rod

Dave Sherburne NY · May 12, 2010

I've got to weld the cutting edge back on to my grandson's loader. What rod should the previous welder have used so I wouldn't have to repair it now?

It might depend more on what kind of job was done and what kind of cutting edge but the simple answer is 7018 or a higher xx18 rod if the cutting edge is high carbon steel or heat treated. Dave

I"ve always used 7018 or 8018 to weld on cutting edges, but lately we"ve started to use bolt-on cutting edges at work. The big thing is to get the right size stick and run at the right amps.

Look at the cutting edge and see if the weld bead broke out of the base metal leaving what looks like a gouge (no bead left on the piece). If so it should have been preheated then welded with 70-8018. If the failure is through the bead then it was welded with insufficiently strong rod probably 60xx. Try with 8018.

if you want wear resistant hard rod use stellite.

10018 low hydrogen on DC reversed polarity would be good.

You don't weld things together with a hardfacing rod and stellite is more common for exhaust valves than buckets. Dave

For backhoe bucket teeth shanks and loader cutting edges/blades I usta use Lincoln 7018 LH and then used a pneumatic hammer to peen the welds a little to stress relieve them.

If the cutting edge is T-1 or AR-400 use 11018 DC Reverse,preheat to 500 degrees and weld, postheat back to 500 degrees let cool slowly.If using mig same procedure ,use ER 80S wire with 75/25 shielding gas. Have welded dozens , never had one to break.

I agree , I thought he said he wanted to hard face an edge

If you are talking about welding a piece on the bucket the best is Probably MIG.If you are talking about hard surfacing a piece,there is hard surface rod for that.

He doesn't want it to break again so there are better options than MIG. Dave
