Save Old Iron 1,571 #1 Posted March 25, 2010 That's the crack in my mower deck. Let's say the crack is 2 inches long. Should I make an attempt to "stop" the crack by drilling small holes at each end of the crack to stop it from migrating? Or just weld it up and call it a day?

rmaynard 16,291 #2 Posted March 25, 2010 My opinion is to weld 'er up. Bob Share this post Link to post Share on other sites
rickv1957 74 #3 Posted March 25, 2010 Depending on crack location,access,and metal thicknesss,I would clean area of rust and/or paint,v-out crack on both sides and weld up,Rick Share this post Link to post Share on other sites
catman81056 3 #4 Posted March 25, 2010 Is it in an area of high stress or is it rust on the underside? Either way I'd cut it out and weld a patch in its place. But thats just me. Share this post Link to post Share on other sites

Butch 194 #6 Posted March 26, 2010 save_old_iron as a former assembler of Gulfstream Aviation aircraft drilling holes at each end is good for stopping the crack from extending. When we had a small rip or tear from a rivet hole our fix was to drill the hole to a larger diameter and put a larger rivet in. And every hole was inspected whether it was a new hole or a repaired hole. Butch S. Jersey Share this post Link to post Share on other sites
sorekiwi 761 #7 Posted March 26, 2010 I'm glad you didnt post a picture of your crack, Chuck!! You said you wanted to learn how to weld, perfect excuse (opportunity?) for a new welder! Share this post Link to post Share on other sites
oldandred 15 #8 Posted March 26, 2010 well pull up your pants then no welding needed :D Share this post Link to post Share on other sites
Don1977 605 #9 Posted March 26, 2010 Cracked decks is not a good place to learn to weld. Find a good welder is my advice. Learn to weld on something that is a lot easer to weld. Thin rusted decks is one of the hardest things to weld. Share this post Link to post Share on other sites

Jersey That's what I was looking for - I remembered reading something about that process being the best way to "stop" a crack from growing (other than pulling up my pants !!). I was not sure if it was for just aluminum or if cast iron / steel could also benefit from it as well. Share this post Link to post Share on other sites
chris11 184 #12 Posted March 26, 2010 Sorry to hear about your crack Chuck. Sounds like a snack. your going to have to weld it . :omg: Share this post Link to post Share on other sites
tarcoleo 119 #13 Posted March 26, 2010 Chuck- Thin rusted metal is not readily weldable, especially when is is necessary to remove a lot of material to get to sound areas. If the location permits, overlay the area with a steel patch and weld and/or rivet the patch in place, depending on skill and location. Good luck.
