Re: 20 feet GI Pipe Ladder project...re-weld/repair

And upon inspection, these are what I discovered !!!
CRACKS on the WELDS !!

Yes cracks on the ugly welds, of the pipe joints and small gussets. I was trying to analyse what caused these cracks, so probably poor fusion of metals, speed travel and wrong amperage.

Re: 20 feet GI Pipe Ladder project...re-weld/repair

And then more joints with weld cracks :

To be continued as soon as I set up the weld machines and start re welding the pipe joints !!

taas ng hagdanan mo !!!
go ahead bro rosy, marami dapat matutunan dyan lalo na sa repairs and maintenance...
thanks !!!

Re: 20 feet GI Pipe Ladder project...re-weld/repair

Good thing you didnt discover the cracks the hard way! Those could have caused a few broken bones or even worse.

Go! Go! Go!

Re: 20 feet GI Pipe Ladder project...re-weld/repair

HEHEHE, well yung ibang steps ay nakadikit( welded ) pa naman, its just that its better to repair and re weld again the step ladder soon, baka mapuruhan pa, "ARAY KO PO" !! 😮

I will be grinding all joints, with or without cracks then re weld again.

Thanks bro joey and jon !! :thanks:

Re: 20 feet GI Pipe Ladder project...re-weld/repair

suggestion po, wouldn't it be much safer if the base would be wider? ladder should taper on its way up (not parallel)

Re: 20 feet GI Pipe Ladder project...re-weld/repair

Here are some pics :

I did also some sort of "shoes" for the base, these "shoes" can be adjusted up or down when the ground is not even.
It also supports the ladder from moving sideways when placed against a wall or a tree.
The holes you see serves as a locking device when a pin is inserted in any of the holes.

Yes bro, what you are saying is true if probably the step ladder was not that tall and heavy duty but what I did worked as well for me since I was also trying to save on cutting different length size of pipe that will be welded. Nag titipid ba sa gastos sa tubo !

Anyway I have already compensated on the wider base when I made those two base "shoes", and it served two different ways, its adjustable up or down and it also supports the sides from moving left to right as seen at the three pics above. :clap:

Re: 20 feet GI Pipe Ladder project...re-weld/repair

OK, just an update of this very slow progress re-welding project on the step ladder.
So all pipe joints grinded, cracks have been exposed, almost all ugly poop welds have been leveled or removed. Well there were some good accidental welds and metal fusion but mostly welds were terrible.

This re-weld project was really slow due to the facts that I have other things to attend to here in my place since it is summer months already and the surroundings is drying fast. Anyway I can only work on the ladder at around 4:30 to 5:00 pm when the temperature is cooler and then probably up to midnight. So after this grinding thing of the pipe joints, then its gonna be re-welding or applying new welds on all the joints. I suppose I'll be using the 3/32" thin 6013 rods and the Yamato DC stick welder.

Pics that I will be posting will not really be that colorful or attracrively interesting but would just probably show you on how the joints would appear after applying some grinding processes using angle grinders.

The top end portion of the ladder.

And the lower end portion of the ladder.

Re: 20 feet GI Pipe Ladder project...re-weld/repair

Here I will be showing individual joints only of one side of the ladder since the other side is just almost the same.

I have numbered each pipe joint so there will be no duplication of the images and so that I won't get lost and confused which pic to post.

Re: 20 feet GI Pipe Ladder project...re-weld/repair

Re: 20 feet GI Pipe Ladder project...re-weld/repair

These pics shows the other side portion on the numbered joints, like 1-A, 2-B, 3-C & 4-D and so on until it reaches the last step which I will not include and that is number 13-M.

Re: 20 feet GI Pipe Ladder project...re-weld/repair

welding galvanized materials is much harder than mild steel.i usually clean the joint with wire brush to remove the coat..or else makikita mo yung weld mo na nakapatong lang sa bakal and no penetration at all..kung makapal naman and no need to worry burning holes, i just simply set my machine to high ampere to burn galvanized coat and penetrate my weld to metal..

sir rosy mas magandang gamitin yung yamato ac mo jan kesa dc..

pls. keep us updated regarding your wips..:pcwhack:
