Re: Cursable Galvanized Sheet Metal

Yes it was a success. Cold galvanized the weld and coated the inside with an asphalt spray incase there are any cracks in the bends or joints. I have a respirator and a fan blowing the fumes away, but thanks for the concern. Making up one out of stainless now, will have pics for criticism, so feel f...

Re: Cursable Galvanized Sheet Metal

Did up another drain pain for a coil housing. Have a larger ss pan for tomorrow morning and then build the framework, mount the fans and wire it up.[attachment=-1]uploadfromtaptalk1400194257234.jpg[/attachment][attachment=-1]uploadfromtaptalk1400194274330.jpg[/attachment][attachment=-1]uploadfromtap...

Re: Cursable Galvanized Sheet Metal

What I found yielded the best results was just putting a wire wheel on a diegrinder and zipping up the area, fit my pipe and put aluminum blocks behind in the corners and blocking off the hole, and a thinner block on top of the pipe to close it in and bessy clamp them together and hit with the wire ...

Re: Cursable Galvanized Sheet Metal

That's actually something that I do after I weld on the drain pipe and finish all the edges. There is a cold galvanizing spray I coat my welds with. I found that the sheet metal is so thing, removing the zinc coating from both sides leaves me with little materi to work with and I don't want to take ...

Re: Welding and Brazing Copper

You want a good mix, even heat ( sometimes preheating heat sinks with a rosebud) and the hotter your torch is, the faster you have to move. Cold welds roll on the edge like milk on the cold metal and hot joints over oxidize and flake and pit and you'll normally blow a hole in it and won't bond worth...

Re: Welding and Brazing Copper

I poke holes copper and glue them back together all the time. I braze Copper to copper headers for HVAC and they quite often come with steel or red brass NPT/FPT connections. I also braze brass distributors to copper leads, with copper pipe spun closed with brass Schrader valves in the end. I use Oc...

Re: Advice Required for Rod Selection.

The shockload on a trailer will be hard on the welds but with the correct supports and layout the force will be distributed evenly. With proper prep and welds both rods will meet and exceed safety standards. Now if your just laying out some square tubing and laying some angle iron for corners and to...

Re: Advice Required for Rod Selection.

I have made many repairs and fabricated many tables, carts and jigs using both E6013 and E7018 and it's more of a matter of purpose and technique as to rod choice. I'm in Ontario and we use E6013 (or farm rod) for fixing tractors and heavy equipment that sees a lot of use because it punches through ...

Re: Cursable Galvanized Sheet Metal

I can't ask anybody any questions because most of the time they don't know so a lot of it is reading manuals, watching videos, and reading forums. I try and take pride in my work and as much as I try and explain to others I seem to be alone there in my thinking. Sent from my HTC One mini using Tapat...

Re: Cursable Galvanized Sheet Metal

Haha, you got it. A Mickey Mouse shop that wants you take take a pile of dog crap and make it a Mona Lisa. Well sometimes no matter how much polish it, it's still just dog crap. And do it for nothing and we bank overtime. It's more me wanting to do things right and make what I produce the shinest cr...

Cursable Galvanized Sheet Metal

I work for a HVAC manufacturing plant and we make heating and cooling coils. If anyone is familiar with that area of the industry you'll know there is a little bit of everything going on all at once. We're not a huge company so the bosses count on a few of us to do everything. I've brazed brass dist...
