Replace BROKEN Tip on Ripper Shank for Caterpillar D11 Dozer | Welding Fabrication

[Music] where is he how you going guys Kurtis from cutting  edge engineering today's job is a d11   ripper tine or ripper shank these are generally  mounted off the back of a dozer for ripping up   really hard ground to make it easier  to dig through with say a scraper or an   excavator or something like that customer's  brought it in and it's broken off the tip so this is pretty common in some of the really  hard ground here in australia this one was   actually ripping what we call quartz so very very  hard rock it's very similar to the blue metals and   stuff like that you generally need to blast this  sort of rock but um in the situation where this   machine is it's too close to housing and other  infrastructure so blasting's out of the question   so common cause for these sort of failures  is you've got a 120 odd ton worth of machine   with 850 horsepower pulling on these so it  is pretty common when you've got that sort of   horsepower to break stuff so rather than trying to  repair the tip just trying to take the old one out   put it on there or even a new one that's that's  generally going to fail in no time flat at all   the customers requested we do a minor tip  on it so we're actually going to cut it   about here through through the rip ripper tine  so after we cut that we'll get it prepped ah   will then fit the new end to it get it all in  alignment and then we'll start the welding but   before we do any of that we need to get rid  of the shin guard so i'm just going to knock   out these two pins get the shin guard out of  the road and we'll get this thing marked out no pressing required all right that's that's loading up already woah woah it's tight aye oh she's in there end of it goes like that pretty good [Music] ah ah sit high five sit shake spin around oh good boy  good boy righto guys so we've completed all  the weld prep on our ripper shank and our minor  tip we've got them tacked together in position   now a little bit on the setup of setting up a job  like this i find it easier to stand the ripper tine   upright and do it when it's upright you can see  everything you can see every line you can sit back   you can eyeball it get everything straight  it is very difficult to get these to align   to align a new tip to an existing shank being that  there is a lot of wear that does happen to these   when they're being used so not real sure how old  this shank is but it does have quite a lot of wear   on it so it's sort of you've got to just educated guess get as close alignment as possible   so first thing i do i stand the the ripper shank up i  tack it to the trestle so it can't fall over on me   i do weld a lifting lug to the end of the minor tip so i can hold that in position with a forklift   or a crane pretty much go through and just do  my best to align the sides of the new minor tip   to the ripper shank top and bottom i then put  a turnbuckle on one side of it so i can move   it around to get it in perfect alignment so the  piece of material we're using for our minor tip   it's a piece of 100 mil biz 80 grade plate so  biz 80 is a quench tampered high tensile plate   very suitable for parts that do come under a  lot of stress they do tend to take a fair bit   of punishment compared to your wear plates  and stuff like that your 450 and 700 grades   we get these flame cut from our local supplier  a lot of people do question are they water jet   laser no these are 100 percent flame cut  using oxy and lpg beautiful finish straight clean once we start the welding process  on this we'll actually lay the ripper shank down   weld one side flip it over weld the other side  try and keep our welds even on both sides to   eliminate any pulling of the new minor tip we  do have our weld runoff plates on so when we   weld that out we'll start from the top or the  bottom we'll start our weld out here run all the   way through the joint and out into this other  plate we'll then flip it over and do the same   on the other side so we're not causing any cold  spots at the at the termination of our weld the process will pretty much just be repeated until we  completely fill up the joint we will pre-heat the   the entire ripper being that it of its actual  size it will suck out heat very very quickly so   we will need to put a substantial amount of heat  into that and keep track of it throughout the job   so now that everything's tacked in  place it's ready to be welded out   once the welding's all completed we've then  got another couple of jobs we need to do to it [Music] [Music] [Music] righto guys so we've completed the welding on  our ripper part of our welding procedure we   do have to give this thing a post heat so we'll  bring the whole ripper back up to temperature   so nothing cools too too rapidly we'll then  wrap it in blankets so it cools down evenly   throughout to avoid any stress fractures  or cracks it's been wrapped up for the past   oh 24 hours now we've just unwrapped  it so first thing we're going to do   we've got to trace out some templates  i've made on the end of the ripper here   cut all the excess material off to shape  it ready for the new ripper boot to go on love shapes [Music] [Music] righto guys so we finished all the shaping of  the end of our new minor tip for our ripper   shank i had to cut all the excess  material off then grind it to size   so we've ground it now so it'll match  up with our ripper boot pretty well perfectly now that that's done we need to put the boot on  the shin guard on we need to mark out the holes   drill the holes and then do some countersinking  for the retaining rings for the locking pins good boy good boy you're a good boy bit too much feed i think [Music] [Music] no break where did he go go get him go on okay you good yep copy what am I saying righto let's go ready yup I don't know what to say Oh my God okay how you going so pretty common here in australia um  tend to break [ __ ] pretty good um it's [ __ ] lost all that this ripper shank is actually out of oh [ __ ] [ __ ] oh nah [Laughter] no don't look at me it has actually broken in the last week   yeah that's pretty much it isn't it you keep going like you you up tone do I yeah hang on you gotta re-reword it so this is one of two that's  broken in the last week [Laughter] righto guys so we've got our hmmm my god ripper shank on our oh [ ___ ] ah so we yep didn't tell you what plate it was okay very good do you want to be leaning on it like that I can lean somewhere else i suppose   a bit of a bit of a dance a bit of a dance it's a big [ __ ] around to try and set these up   uh now that all the weld prepping's  been done we can we put it oh [ __ ] all around the shank so it's  very hard to get an alignment from ever   from um every cylinder which [ __ ] that's really hard to explain so when we start the welding pro process of  this plate we're actually of the [ __ ] um we'll have to keep keep track  of the heat throughout the job   to keep track of heat through  throughout the job during [Laughter] we're gonna have to keep it hot all [ __ ] day  pretty much um pick a suitable filler material   for the weld joint and you shouldn't have any  dramas with that that was a random addition yeah [Laughter] anyway do you want to come on this side oh and then commence the welding righto guys so we finished all the shaping of the end of our new ripper um [ __ ] gotta mark out some holes and some  counters out righto guys so we finished all   gotta mark out some holes and some  counters oh righto guys so we finished all   the uh all the ah set so we finished all the shaping of the um the new tip oh going well going awesome righto guys so  we finished all the oh goes [ ___ ] ah i'm just gonna do it again woah woah woah [ ___ ] hot [ ___ ] [ ___ ] [ ___ ] dog [ ___ ] and that [ __ ] first bit sophisticated template [ __ ] nothing better than some shapes [ __ ] [ __ ] get up what are you doing he wants mummy hey you want mummy anymore anymore it's all gone it's all gone
