Guest butlersZ Posted September 6, 2004 Share Posted September 6, 2004 Hey guys, What do you think of this weld? It's on SS. http://hybridz.org/nuke/modules.php?op=modload&name=coppermine&file=displayimage&pos=-1671 Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted September 6, 2004 Share Posted September 6, 2004 Very Nice! Quote Link to comment Share on other sites More sharing options...
ToplessZ Posted September 6, 2004 Share Posted September 6, 2004 Thats really good. Tig I assume? As long as it has really good penetration that is the best Ive seen. Curious what the penny is for though... size comparison? Quote Link to comment Share on other sites More sharing options...
DaleMX Posted September 6, 2004 Share Posted September 6, 2004 Very nice, was it done my machine or hand? Just wondering cuz my local welding supply had a sample that looked that good that was done by a machine. Dale Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted September 6, 2004 Share Posted September 6, 2004 If you learn to walk to cup you can slick it up even more. Look great for free hand. Quote Link to comment Share on other sites More sharing options...
johnc Posted September 7, 2004 Share Posted September 7, 2004 Something's odd. Maybe its how the picture is taken, but the puddles seem to have a small lip as shown in the puddle next to the penny. There's also not much of a contrast between the normal discoloration in the HAZ and the base metal. What base material? What filler? How thick is the material? Why the bevel? I'm not being critical, just curious. Quote Link to comment Share on other sites More sharing options...
Guest quadcamZ Posted September 7, 2004 Share Posted September 7, 2004 I would be proud of that was my welding. Nice Quote Link to comment Share on other sites More sharing options...
Drax240z Posted September 7, 2004 Share Posted September 7, 2004 Weld has been wire brushed since it's been done... the best way to tell a quality SS weld in my experience is by weld colour. But it's gone! Quote Link to comment Share on other sites More sharing options...
Guest butlersZ Posted September 7, 2004 Share Posted September 7, 2004 Here's a weld with color. http://hybridz.org/nuke/modules.php?op=modload&name=coppermine&file=displayimage&pos=-1673[/img] Quote Link to comment Share on other sites More sharing options...
Guest butlersZ Posted September 7, 2004 Share Posted September 7, 2004 So how do you tell the quality of an SS weld by color? Yes, the penny is for size comparison and yes, it's TIG. I'm rather new at welding, I have about 800 hours of welding under my belt. I have learned from a lot of people. I have only used MIG and TIG, but never stick welded! I have never tried arc welding with a simple stick welder. It seems almost sacriligious. Please rate those two welds on a scale from 1-10. 10 being perfect, 1 go back to school. I'm in need of a confidence boost for a cherry picker that a friend and I want to build. We want to make one that you can tow behind a vehicle that has one axle with a simple hitch. I was thinking about using an actual trailer frame and strengthening it, then building an engine stand one the front half and a swiveling engine hoist/crane on the back half. That way when done building the engine just swing the crane around,lift it up and drop it into the vehicle. Sounds simple right? I just want to make sure that my welds will hold up to the lifting capacity I want to achieve. I know the metal we would use will not be SS but using that SS sample above being the best weld i could accomplish, you think the welds would hold? I know that the design of the engine stand and crane will be critical to the amount of stress on the welds. I can weld just like SS pics above on regular steel without any problem. I have never built and engine stand or engine hoist before, I just don't want to be on that trailer if the engine would happen to fall due to a weld breaking. Or even worse, have a friend on it! Anyone have any advice on building a hoist or stand? Any input would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
innerware Posted September 7, 2004 Share Posted September 7, 2004 Really nice looking weld. I would say that if you could do that all over it would be a strong ass hoist. It really comes down to penatration though. It might be a beautiful surface weld but not penatrate the metal much. What kind of filler rod ws used if any. To get a really good weld usually the two parts are chamfered and then a rod is used to fill the gap as you run the bead. But it is definatley a clean weld. Try hitting it with a hammer too and see how strong it is. Quote Link to comment Share on other sites More sharing options...
johnc Posted September 7, 2004 Share Posted September 7, 2004 OK, better picture. Weld looks good and the bevel's there because its thick materials. Good weld, if you can do that consistently you're cherry picker will be a thing of beauty. Quote Link to comment Share on other sites More sharing options...
2126 Posted September 7, 2004 Share Posted September 7, 2004 Looks extremely good!!! Now pratice verticals, overheads, and varying the thickness of your materials. You definitely seem to have the touch and steady hands. Welding is as much an art as it is a science. Again, really nice welds! Quote Link to comment Share on other sites More sharing options...
Tony D Posted September 8, 2004 Share Posted September 8, 2004 With a weld like that, I would not worry about the integrity of the cherry picker. With what I have seen lift engines gobbed together with a bizzbox while the welder was half drunk, you could probably pass for a cherry picker to lift components for the space shuttle... Though then what it looks like on the outside isn't what they check... Quote Link to comment Share on other sites More sharing options...
Guest butlersZ Posted September 8, 2004 Share Posted September 8, 2004 Thanks guys, I'm gonna come up with a final design drawing of my engine hoist and engine stand idea and will submit it here and see what you guys think before I build it. I definitely will need the feedback, I want this to be the ultimate hoist/stand. Once built, I'll post pics and such outlining the process. Maybe I'll get a couple HybridZ stickers to label it Haven't decided whether or not to use a hydraulic ram for lifting or an electric winch set up or ...What do you guys think??? Or maybe a combination of both using the ram to lift the boom up and down and use a top mounted winch to do the rest, ahhh perhaps thats overkill. Perhaps I should start a new thread with this one Quote Link to comment Share on other sites More sharing options...
johnc Posted September 8, 2004 Share Posted September 8, 2004 a hydraulic ram for An air or electric powered hydraulic ram would be perfect. Quote Link to comment Share on other sites More sharing options...
Tony D Posted September 8, 2004 Share Posted September 8, 2004 Concur, Hydraulic Ram! I would go with a Hydraulic Ram that is hand-operated with a separate pumping unit. That way the cylinder/actuator is easily switched to a powered hydraulic pumping unit. This way, you can use an electric pumping unit, or an air-powered pumping unit to lift/lower it (as well as pumping it up by hand) If you choose Electric or Air, if your utilities go out, you are SOL. WIth Hydraulics, you can still go by hand, or swap between any of the trhee motive forces for the pumping head (if you use actuator-only). Harbor Freight has some very inexpensive 4 and 10 ton air-powered pumping units for hydraulic rams, and their 4/10 ton porta-power kits become usefull for scavenging parts when you start fabbing stuff like this. Good Luck! Quote Link to comment Share on other sites More sharing options...
