6G Inconel | MAX TIG Welding Procedure | F34, F4X !

hello everyone and welcome to the X3M TIG   channel for today's video uh we're going to do 6g   it's going to be Inconel uh max tig  uh or F34 /F4X uh so the prep   is going to be feather edge uh for the internal  cleaning I'm just going to use that carbide   bit clean it like half an inch from that edge  from the outside, we're going to remove the mill scale and uh leave that feather edge okay that's how it should look nice and clean   it's going to be purged it's a way the backing  gas so we don't want any impurity inside   even though Inconel is uh it's not really  easy to weld it's a little bit difficult to   manipulate a puddle uh okay now for the gap is  1/8 I'm going to use the bridge rod for   tack uh you can't do any root tacks or bridge  tack with you with the wire itself it got to be   gotta be bridge rod so I'm just gonna put one tack  on the 12 o'clock and we're gonna flip it uh   flip it around check for the gap if it's even  then we're gonna put another tack at six o'clock okay gap looks good we're gonna  put one on the six o'clock once where the tack is done we're gonna check  for the gap on uh two sides or three or nine   o'clock if it's good we're gonna you put whatever  the side you like if it's one side uh got a little bit   more gap you can put there just to make it even  okay we got three tacks we're going to position in   a positioner you see I got a hole here that's for  purge this is where I connect my purge hose so we   can purge that spool I'm just going to tack it in  positioner so we can leave it at a 45-degree angle okay now we got 45 gonna lock it so while the  examiner already marked that spool it's uh   that's how he knows that stop so you can't cut  it or flip it or whatever so for the filler wire   it's uh Inconel 625 it's a chrome uh it's  a Nickle Chrom Moly-3 as you know that Inconel is a super alloy that possesses high  strength properties and resistance to elevated   temperatures so this is my plan planning from  On the outside, I'm going to use a 3/32 for the root playing on the bottom side keep the rod  inside and try to keep the rod in that puddle uh Inconel refers to a group of specific nickel  chromium alloys they're using different welding   processes I don't know if you guys have  much experience with the Inconel   it's a little bit difficult to manipulate  a puddle as uh it's like lots of impurities inside   uh so for the purge I'm gonna go up 30 just  leave it together to have nice good coverage   just gonna check I got a nice flow  just gonna leave it for a couple of minutes Inconel is difficult because the  welds that are created have a tendency to crack   and you're gonna see it later I'm gonna show you on  uh uh on a video it's actually how you get it uh   impurities on the top of your weld and it's  uh it's a little bit difficult to stretch okay   that's the plan you can do both uh both things  you can do it from the inside like a back feeding   uh free hand I'm gonna use a free hand okay I'm  gonna start here the only problem I got here   uh I set up purging 30 but i forget to lower it  down so it's pushing my puddle out as you can see   I'm just gonna push a little bit more and then  I'm gonna stop I'm gonna lower it down to 15. okay now I'm gonna cut that tack and I'm gonna  grind that stop as you can see there's a little   the way how it pushed outside so  I'm gonna I'll have to grind that   grind it out and continue okay now for the  continue part preheat and start adding uh   wire try to try to keep the wire  in a puddle it's kind of easier, uh but I mean   things changes always so do what  you can try to keep it in the puddle   especially on the bottom side  all the way once I get up   to 10 o'clock then I might start  pulling out and maybe just dip the sides okay I'm just leaning up the bottom side  of the cup inside that groove inside the   just bevel rest my hand a little bit  a little bit shaky for this video   so the top part that's what I'm  doing I'm just dipping sides good I'm gonna stop okay now we can uh  remove those two tacks on this side   grind all those stops and starts   and you can continue on this side so for this side  I try to keep my rode the inside that root as I said especially on the bottom part you  can pull it out slowly once you get up on   up on the two o'clock just use precaution because the gravity  might sag down you have some grapes   that's why I usually like  a little bit stronger purge   so it forms my uh root inside a little  a bit better especially to prevent uh grapes   it's not that beautiful outside as I said it's a  it's a little bit difficult lots of impurities it   actually, it looks like it's because all that  uh composition that contains uh that rod we got a copper got lots of different materials  okay the root I forgot to take a shot of the   root a little bit earlier so I kind of have not  much room here to make a nice clear shot of the root   already looks good maybe a little bigger on one side but uh that's completely fine as you   can see the root pass from the outside doesn't  look really beautiful it doesn't have to be   it's not a beauty contest as long as it's a  quality it should be fine that's what I'm   adding right now on the top side I'm just  dipping that rod so I'm going to remelt   that little built-up uneven spots that I have  on the root pass so make it nice and even   for my hot pass so every other pass fill pass  all the way up to the flash it's gonna be easier for the hot pass I'm uh I'm around 120 at 125 I'm just adding on the sides as I said I just want to make it up nice and even  because that uh outside root pass was a little bit   uneven a couple build-ups and couple a couple few  spots okay for the hot pass that's it that's what   I want uh for Inconel it's really important  to run a buffing wheel every time every pass   run a buffing wheel if you want to have a  clean each pass there are lots of impurities inside   and uh okay so now for the fill pass first  pass I'm going to start on on top side I'm still using a 3/32 rod for hot  pass and for this fill pass amps I think it's 130 okay we're gonna run one on the  top and then one on the bottom and that's what it is pretty much  that's the game all the way up to the flash   you just wanna put those  uh layers put a nice beads make it all nice and even all the way  to the up as I said clean each pass   now I'm gonna go again on the top side  all the way up and then we're gonna   like I go top to the middle and then from  the bottom to that uh half of that top pass and then once you get to the  the wider area then we're gonna   then you're gonna have to go like  three passes even four depends I don't know if you can see it here on this shot  how actually that uh that puddle actually it's   not easy it's not easy to manipulate it's uh  like that impurity inside, it's hard to control   that's why it's a good habit to keep that  rod constantly inside that puddle try to   keep it inside as much as you can if you can  if not I mean you got to do what you have to do   you can uh still pull it out and put it in and but  still kind of that connection is uh it's a little   a bit harder you know every time you continue it's a  a little bit to connect to establish that nice flow okay now I'm using 1 /8 rod from now on I'm going  to be using 1/ 8 all the way up to the flash   now it's pretty much it's the game just uh fill  fill all the way up cleaning clean each pass don't go too cold go even up you can go 150  if you want 150 160 whatever you feel like   whatever you feel most comfortable  with that amperage, you can handle okay I did one on the top now  I'm going to do the bottom the way how you feeling you just want  to make it kind of even level if you do the proper steps okay I speed up  and now we got a flash fill to flash   three passes pretty much that's  what is okay so for the cap   for the cap, I'm using a 3/32 rod and I waited  for uh maybe half an hour just to cool down   you know it's easier to put it to start  doing cap so 3/32 amps uh 130 walking the cup try to keep the rod in the puddle as much as  you can keep it on the top side of the   puddle and then just uh stretch down keep your  line straight as much as you can let that edge   be your kind of guide so you just want to cover  and then just follow that puddle that edge   that you got okay for the second pass same  thing 3/32 start preheat and uh find those self   you can go half of that you can cover half of  that to root but half of that uh first pass but   you don't have to go that wide with that step  usually, it's like just cover 25 % of that first pass as I said you can see like it's uh it's really   it really gives you it's really  hard to manipulate that puddle okay for the third pass same thing try to plan  you know calculate how many passes you're gonna need depends on the steps and how wide you're going  how hot you running you can use one eighth rod   I didn't want to go with one eight I'm just 3/32 yeah that's my third pass clean after each pass okay and then for the fourth pass for  the fourth uh pass of the cap final one   we got a little groove here between that  weld and the pipe it's like a little   wagon track here so I'm just gonna dip the reason why I'm dipping here on the top   and not holding the wire inside the puddle  is just uh because that little groove I wanna   I'm just trying to be sure that everything  is uh melted like a hundred percent and I'm   gonna melt the material and uh and the wire so i  can so they're gonna be blended a hundred percent I mean both techniques are good when you're doing  6g especially on a tig in 99 percent I'm pretty   much walking the cup on my root and my fill  hot, fill uh fill cap and passes but uh you   gotta be you just gotta be sure to run hot and do  small steps you know any missed steps something you can   you can maybe see it later on at a band  test okay that's it for the for the   for the weld, part is down now we're  gonna cut all that hard work   it's gonna be nice and cut  with acetylene torch   they're gonna cut in uh four pieces then we're  gonna grind so you got two roots and two face okay we got a grind root sides cap round the edges don't chase too deep even if you got something  you can there's something there's a lot of cases   like there are some spots like porosity but  that's mostly from cutting from that torch   they're using it to cut those pieces so though  even if you got don't go too deep don't chase it round edges and now we're gonna go for band test okay as i  said we got uh two roots and uh two face band okay let's see what's gonna happen  to this heartbreaker machine well if you did the proper steps as I showed  in this video shouldn't be worries much just go nice and slow you know do proper  steps and everything should be right   okay first piece looks good  second one the same third and the last one that's it okay thank you guys   uh thank you for watching please support  subscribe, like, and see you at the next one, bye!
