Outer Limits 4x4 Board

hey all, im doing a widetrack conversion to my sierra,
anyone know if its possible to weld the spring perches on to the axle tubes with a mid sized stick welder and reasonable welding ability?
or should i leave it to a pro with a mig

If u can use a stick it will be fine. Its not the welder that makes the weld it is the person using it.
Its the "U" bolts that hold the spring to the diff the perch just stops the diff from turning, so even if a weld does crack (which is highly unlikely on a zuk unless its a really bad weld) its not going to send u off the road into a tree.

I did my NT-WT conversion with an Arc welder. No problems at all
On my old SWB chassis I moved the spring mounts too.

Jas.

Most of my welds on my zuk are stick , Cheers Paul.

thats

thanks for the replies, ill have a good crack at it.

Stick welds can be stronger than mig if done right.

what do you think we used before migs were invented

Bolts and Rivets.

Arc will be fine, go nuts...

structural welds and pipeline and preasure vesels are still stick welded. Its all the operator and grade of rods used.

thats true and oversea on pipe lines and structual welds are all stick welded because mig isnt seen high enough quality. having said that the olypic stadium in beijjing was mig welded.
if a stick weld looks good, good chance its a strong weld. cant say that about mig though.
i am currenly welding on shock mounts onto my zook all stick vertical stick welds.
if you want ill post some pics tomrow of the welds

Not many gas pipelines or other pressure piping are <3mm thick though. Even so, many weld procedures for pressure piping specify a Tig root run to ensure penetration and then stick to fill the groove up. 2" Sch 40 pipe (3.7mm thick) is rarely welded with stick, it's generally Tig

I've even seen procedures for pressure piping welded with flux core Mig (gasless)

for structural welding stick will still be used on site due to access restrictions making mig machines too bulky and environmental factors (wind) blowing the shielding gas away. In any case, most structural (building) welds don't need to be of a very high standard and don't require a very skilled welder.

In the workshop though, the speed and versatility of mig means that most structural work will be mig.

Arc will be fine if it's all you have. If you're not skilled with arc though, it might be better to get someone who is to weld it. The biggest problem with arc is that because it's not always all that neat, the temptation is to keep grinding it back and touching it up and that will add a lot of heat to the housing, no something you want to do.

Petro-chemical (oil and fuel) pipelines are still stickwelded, I'm talking 12" plus dia. The root is done reverse polarity to get a smooth intenal weld.

When I said structural weld I was not talkng about building an industrial shed. We build mining equipment and a mate builds heavy structures and conveyors and low hydrogen rods (for eg.) are still commonly used.

This is besides the point, 2.5mm gp rods will be fine for sping saddles.

anyways, i was just asking because most of the barwork and shit on my car was done with migs and tigs, and i only got a little stick welder at home.

so i had a crack at it, and it seems to have turned out OK. ill post up pics when i reassemble, hopefully tomorrow

Not all. When I was making hydraulic rams we used flux cored wire and gas to weld end caps etc and some of the cylinders were 16" diameter (Took a whole day to fillet weld the trunnions on them to required weld size!) and some telescopic ones for the forklifts at container docks in Malaysia. We did just use stick to weld all the ports etc on though.
Arc welds have a higher rutile strength than solid wire mig welds anyway so his spring perches will hold up well.

I was not stating all are done this way, just that they are done in this mannor. People think MIG is the be all and end all of all welders.

Bwahahahaha tig welds my friend, seriously.

But like mentioned stick will be fine, and a good welder does go a long long way (unlike mentioned) and practice on some scrap and get your amps perfect before you try.

Slightly off topic here....

When I was doing some welding courses I was told that in WWII whent he yanks were building warships by the dozen the welders were being paid by the yard welded.
To speed things up the welders were then just putting a unused welding rod in the gap and weld over the rod complete with flux.
And they wonder why so many welds broke when hit by fire/mines/what ever else Germany and the Japan threw at them.

Seriously, you need to get out more. A mate still owns a company that does nothing but Stick weld fuel pipelines. Last year he personally welded 500km of Fuel pipeline.

Next thing you will say nobody uses Oxy Acet or ARC gauge anymore, its all plasma. What about Sub ARC and thermal lances?

Just because you don't do it a specific way, does not mean it is not done that way.

I'm aware of flux core wire for mig, and companies in the U.K. do use both flux core and stick.

Anyway dad has his answer.
