I see a lot of "internet experts" criticizing the beads, and I will say they look a bit squiggly...but how many of you can do that good with your knee, elbow, or other appendage on the pedal? There's a big difference between cage and chassis welding, and sitting in a comfy chair with all your parts on the table and your foot on the pedal.

Thank you for the information on welding chromoly. I'm restoring a vintage Trek bike. I'm not a welder. But about to get a welder to weld a rear disc brake adapter on a frame. Did the research, have the plate sizing etc. Was told Chromoly is different than say, Steel. So a TIG weld machine is needed....

Producing good welds inside a cage frame like that is very difficult. It's much easier doing it on the bench, but then how many flat chassis have you seen? I like the bit about how a weld is like your signature......my welds tend to say "whoa, boy. what happened here? Why all the squiggle and what's that lumpy bit you tried to grind off....?"

Ill take another look at the video but was inquiring about the filler of choice for chromoly and yes roll cages, as well as suspension components (a arms,etc.) Ive heard many say ER70S-2 is fine and some say Er80 is the best. I figure these guys being top-notch builders was curious what they use for the cages. Im getting ready to do mine and was wanting that input, thank you for your reply.
@MillerWelders
8 жыл бұрын
+Brian B For roll cages, ER80S-D2 filler metal would be the best choice and the ER70S-2 would be a 2nd. The ER80S-D2 more closely matches the 4130 base metal strength while still having acceptable elongation percentages. This is a very common choice for this particular application. Make sure to avoid a 4130 filler metal or stainless steel filler metal (like 312) on the chassis. The weld is too strong and it will crack along the heat-affected zone during use. Hope this helps!

With the cro/moly it helps fusion and post weld heat if the tube is pre heated a little before welding....not much, just enough to sweat out the moisture (this is used on tubing thicker than 3mm as a rule of thumb). overly large fillets aren't necessary or wanted as the video explains, embrittlement is caused by excessive heat in the weld. Also the heat can be lessened by using the pulse setting when welding (if it has it). As for the foot pedal....ditch it and get a thumb remote!

@alibong00 no its says:" cooling too quickly causes embrittlement." hand or foot control is just personal preference.
@alibong00

@markbenoit Sorry I wasnt clear, using excessive heat in the weld, causes more grain growth in the metal adjacent to the weld than you want. This in turn causes embrittlement in the grain structure. You really want to keep the heat input to a minimum with low alloy steels. using the big unnecessary welds to heat the steel is just silly.....use proper pre and post weld heating and cooling to control the quencing effect of the parent material.

I really hate to be critical of someone else's work, however, If that frame was being fabricated for me; visual inspection of (some of) the welds would cause me to reject it for lack of Q.C.. By trade, I am a journeyman electrician, who frequently welds on power plant's in the construction and up grade phases. ( I purchased a Miller 330abp tig welder in 1979, and use it to this day in the shop- I use a miller Trailblazer 302 in the field with either a h.f. arc starter, or a Spoolmatic 3 spool gun for aluminum bus bar and aluminum cable tray fab / repair...

Thanks for the video @Miller Welders, I am a fan of your equipement, specifically the Miller Dynasty 200DX. Now, my question is, how can I achieve a fit up that great? It seems like whenever I try to shape the welding end of tubing one side is uneven, so I grind it, now the other side is uneven, and after I go back and fourth with that I end up shortening the tube by 1/4"! surely there's a more effective way of achieving a good fit up.

@martinmartiini Welded benches, welded seats, desks, tables and many other things are quite a waste of welding then. You can make all of them out of wood and save the welding for something important. There is enough filler material and electrodes to go around. They aren't a depleting resource like Oil. In welding schools they have to throw away thousands of dollars of welded material every week but it gets recycled into new steel and fillers.

I know its really tough to just get to all those spots on that that car frame. The vid shows an easy spot where the camera can see the guy welding. There is all kinds of out of position spots there where I'm sure the welder has to stand on his head and cuss (and still produce decent work). Imagine crawling in and out of that frame to go grind your tungsten every time you dip it. Your skills and advice are good. Todd, Thanks for sharing. What was that number of tig rod you're running?

4130 is a terrible choice for welding chassis. The tubing has been drawn back allready and is not at its full hardness, So why put hard filler into it?Also, The melting temp of mildsteel vs er-80 vs 4130 is a big difference in how much heat you have to put into the joint. There is a reason NHRA requires er-70 filler and also a reason that NOBODY who knows what they are doing uses 4130 filler anymore. 4130filler wire is pefect when making small parts that get heat treated after fabrication.

"welding chromoly we want to concentrate the heat in a same area" wrong! this is what tig welded does, not is what is needed for welding chromolly. concentrated heat causes the weld to cool to fast causing stress to build up in the welded joint. this is why gas welding aircraft frame's works so well. this is one of the biggest misunderstandings of welding chromooly.
