Ok, well I am porting my wastegate on my 87 TII and I came to a small problem...I dont have a welder, SOOO...I thought maybe I can try JB Weld. My question is will JB Weld stand up to the heat of my wastegate or should I get someone to weld it on for me. (the newer bigger flapper door) I dont want to do this and then it fall off and small piece of JB Weld or a BIG flapper door end up wrecking my turbo. So maybe its just a better idea to weld it in.

NO!
Read the directions of the JB Weld, it'll catch fire!

 

hahaha...ok that was easy enough. i think its time for me to buy a welder anyways so i might as well...

 

It will not work. When I was younger and inexperienced I tried using it to seal off an extra 02 bung on a downpipe and it burned off. Smelled terrible too.

 

Absolutely not. It can't even come close to handling the temperatures. If you ask nicely, I bet an exhaust shop will weld your flapper on for a cup of coffee or two. It's only about 30 seconds of work.

 

yup get an exhaust shop or any place that has a welder to do it takes seconds or like you said buy a welder and do it yourself i wish i had money for a welder they are very handy

 

yeah well my friend and i are gonna pay half each to pick up a 200 dollar welder...he drives an 88 mitsubishi starion so we are always needing it for little things. i have welded in the past and i can lay down a decent bead but i just havent owned my own welder...

 

yea are you getting a mig welder or tig i use all types of welders at my school

 

he said $200, never heard of a $200 Tig welder before.

 

GOOD LUCK with that welder.... If it diesn't have gas capability.. you are going to be in for one hell of a splattery spittin mess..... And you'll probably burn the friggin washer up in the process.

I gave up on the little 120V lincoln i had and sold it to my neighbor... I just drive the 1/2 hour to my fathers garage and get him to weld my stuff now with his wango tango big assed Miller welder.

I'm saving up right now for a good TIG setup and am going to take a couple semesters of wleding at a local trade school, because, while my father is the WIZ bang MIG/stick welder guru... He's never used a TIG, and therefore, can't help me out much!!!

I can weld a trailer frame together with a stick welder like nobodys business.. But, you can't do body fabrication or weld headers with a stick welder (OK... you CAN, but you have to use two sticks... one on the clamp and one as a heatsink and feed it like you do with the filler rod on a TIG and its a GIANT PITA)

 

so wire feed mig is no good then? how about oxy acetelyn...my neighbor has one im sure he would let me use for this little project...im not good with it but he is so i could just have him do it...

 

neither have i but some people find a hell of a deal on things oxy would be ok to use i think might be alittle hard though i use wire feed mig welders they dont shoot splatter ***** that much at all if you are good at setting up the machine to the right settings when i get a welder i don't know what to choose from a MIG or TIG both are great imo all the welders i use are miller welders thats what brand i would buy

 

Mig will be fine for this, but as he stated, make sure you get one that has the ability to use the stabliziing gas, or it will splatter/burn stuff.. With the gas, no problem.

 

The gasless wire people are refering to is called Self-Shielded fluxcore (SS-FCAW). It is a spatter mess. When buying a welder you want to make sure that it can weld solid MIG or GMAW wires with gas. The real cheapo units only weld self-shielded fluxcore. It may be attractive to not require a shielding gas but it is not.
Also note that the cheapo units 120V can only weld small diameter wires. To expect to weld 1/4" or greater thickness metal with that kind of machine is not possible. For thin material they are ok.
Good luck with the welding!

i use a 130mig with Argon/Oxy, works ok for all types of welding but i have to turn down the gas while welding with steel because it tends to burn a bit hot.
