How to TIG Weld Cast Iron with good success 440 engine block broken ear for 71 barracuda episode 10

In this episode I go over how I have had success welding a 440 Cast Iron engine block for the 1971 Plymouth Barracuda we have in the shop. Correction to video I am DCEN not DCEP as stated on my settings normal DC TIG hookup with leads. I was multitasking and said the wrong thing. I give you a step by step walk through with lots of tips and tricks that might be able to help you with you cast welding project. If you have a Dodge tall deck big block you might have the same issue.

I had my 440 block recently repaired by a professional welder. He repaired the ear on the driver side that bolts to the bell housing where the starter goes. The through hole casting cracked off and he filled the entire area starting at the halfway mark where it broke until the arm hard enough solid weld to drill another hole.
He used “Super Cast” mig wire made by United Alloys to make multiple passes over each other. First he preheated the area to weld to 300 degrees checking with a laser temp gun. It was thoroughly cleaned and wire brushed of course. After each pass he peened the weld with a dull body hammer for a couple minutes. After each weld he wire brushed and peened for pushing the welds down and relieve stress. It took close to 4 hours to complete the building up of welds but it was a professional job and worth it. This was done to a long block that was just assembled with gaskets and sealant. Luckily the area was about 4 inches away and was on an engine stand to help with gravity. The wire does have nickel content. The gas was a 75 percent argon but 90 percent is preferred for less spatter. You can always call United Alloy for questions. One benefit using this rod is that the material after welding is machinable. If you want more details feel free to contact me. There was none of the preheat procedure with the block you used at all. Preheat the area and mig. Hope this can benefit you or your customers some day. United Alloys for more information is 800 356-WELD. Thanks for great instruction and for your responses. Keep making your videos.

When you install the engine chain or cable it to the frame so you're not yanking on the motor mount..😁 you did a good job on the welding!

[garylietz]

I just learned a huge amount of information.... thank you.

[markcollins]

Beautiful job, only practice gets results like this😊

That was a good vid. I watched a patch job vid the other week that was welded around the edge and then an ordinary steel plate welded in the gap as filler. Saturday I saw a singe cylinder repair that was a half pipe with a bolt every 3/4”. It must have taken days to drill and tap, never mind forming the sheet to fit the casting. Looked like it had worked and held water for decades :o)

I've been looking for advice on this exact repair for my mopar 400. Thank you for uploading this. Subbed.

Great work. I have a 1970 “F” 383 HP block with the same ear broke off. I’m gonna give this a try and save that block. I’m wanting to build a 496 stroker with it for my 71 Challenger. Thanks for the video!

Those flying sparks are the carbides burning in that iron (real good sign, shows your puddle is casting temp, so really getting alloying fusion rather than stacking metal on top). Damn fine work! If you ever have to do it again, bust off a pencil and put it in the tube before you start laying metal, it burning will eat the oxygen, preventing that oxide slag/scale/crud from building up (any old chunk of wood will do, twig, dowel, pencil, even packing it with dried lawn clippings, lol)

Thank you man you are clearly very competent and talented. Thank you for sharing!

[edsmachine]

Very nice repair.
Well done.
Thanks for sharing.
Take care, Ed.

Mr. Beasts?! Man you’ve really met yourself go 😂😂😂

I'd be curious to know how much the heating/welding affected the crank journal alignment, cam journal alignment, deck square & flatness.

You mean CK20 water cooled torch. The 9 torch is air cooled.

What would you use or do…… ford 302 gt40p head passenger side. Exhaust manifold bolt broke heat did not work, broke sticking out part. Drilled and tried easy out with glowing hot heat. Did not work. Worked my way up to 5/16 barley getting factory threads used 3/8 tap to get out resisting bolt was not coming out. Went for another pass was just not really taping was hard to thread so used one of those in between bits and went a touch too far hit water jacket. Tried the tap again it broke free the existing material from bolt tried backing out tap broke. Could only move from 1 o’clock to 2 o’clock tap was moving but not the tap it self just the existing material. Had no choice but to punch and break tap to get out. The tapered tip still stuck and went sideways. I know I know I should have just put my manifold on my mill and took enough out of the 5.0 explorer manifold to get a nut on the broken bolt and shouldn’t have fucked with it………
Waiting on 3/8 diamond tip hole say that comes today via Amazon. To cut left over tap. Now what do I do about the water jacket hole. I know on this motor the head bolts need thread sealant because they pass into the water jacket.so should I just thread seal the time sert and then the manifold stud. Or weld it. “ try to weld it” and repeat. My thing is with the sealant. The temp rating is only 400* I’ve used my ir temp gun to read the temp of the runners of my turbo car and it well exceeds 400* at idle on tubes. Am I just not seeing the right sealant for the job

Is that engine for the 71 barracuda your working on ?

with all due respect brother, the kid is too close to not having him wear a face mask for his eyes

Electrode negative means the earth clamp is positive and the tungsten electorde is negative
