Question about steel

[Alexey]

Hello my dear friends and comrades. I hope you are allright. In your home, order and understanding. You rejoice in life. I am very happy if this is so. I wish you smiles and love to you and your families. .

Now let's get to the point.
My motorcycle ridgeback 2005. I need to do some welding on the frame. Do not worry. The frame is in order. I just thought of something. . Please tell me from which brand of steel the frame of the motorcycle is made? I'm afraid of making a mistake in choosing the type of steel and breaking the welding technology. And this is very important.

Here is a decent article on the subject.

As far as confirming what tubing was used, Pauls suggestion would prolly be best.

Thank you, guys. Interesting link. I read.
I tend to use seamless cold-drawn steel 20. This is analogue 1018 or 1020 according to the American standard.
About the test spark. I know about it. But this is not a very accurate test. I posted this question on the Big Dog factory. The guys answered that they did not know the grade of steel. So I decided to ask here. It is very important. If I weld too different steel grades, then this can cause cracks and an accident. I do not want it. If someone knows the exact mark of steel frame big dog ridgeback 2005, tell me please. Thank you so much.

Messer MG 600 welding rod is for use with dissimilar metals or unknown composition of base metal. I have used this before with great results, have a look anyway, decision is completely yours just offering a viable solution.

Good information. Thank you. I'll keep it on mind.

What exactly are you making?
Is it something under high stress or just decorative?
DOM, drawn over mandrel, is the common preferred material for stress applications. Exactly which DOM is dependent upon exactly what your intended use is.

That MG 600 rod is what I use to weld Jap bike cranks, and also Harley crank pins. Works great, and some of th hardest stuff you'll ever come across.

This will be a high load. For modification, I decided to use 1020 steel. I will use a seamless pipe. What is drawn over mandrel? Is this a seamless pipe designation? grade of steel 1020?

For welding, I plan to use a semi-automatic welding machine. In the environment of CO2

 

[john sachs]

I've used 1018 or 1020 on frames with great results.

You heard it right from one of the Masters mouths. Can't get much better info than that.

Please correct me if I am wrong, but most of our frames are welded with gas tungsten, the gas provides a good shielding which helps against welding contamination and reduces chance of porosity. I have never used 1018 or 1020 but if you are stick welding rods of 6010, or 6013 are deeper penetrating rods and usually used for structural welding. Personally I am a big fan of gtaw. It makes less of a mess and provides a clean weld without slag. Just my 2 cents on welding..

I would assume daytec would have used GTAW process ER70S filler. 1018 or 1020 tubing is very versatile when it comes to welding, you can use stick, mig, tig, all with great success. I have never used 1020, but I was told by a couple people I know that it is a bit more brittle and difficult to machine, don't know if there is any merit to that or not.

What the hell do I know about welding lol.. ?? I am getting my degree in it, but have allot to learn. I will say that tig welding in the vertical and overhead positions suck.. look like bird shit
flat and horizontal positions, well they look pretty close to dimes on the plate ..

25 years ago, when I was a welder, the weld tests were made on pipe set at a 45 degree angle, using whichever process we were running (mig - tig - stick ) testing included bend , pull, and x-ray, Personally ,I liked tig above all the rest. Once ya get onto "walking the cup" you'll never want to switch to any other process. Just my opinion !

The seem less tubing has a much higher tensel strength. That's why we use it in derricks on drilling rigs. Usually 1" (A-106-B)should be in the neighborhood of about 30,000 lb. the 2.5" if I recall is 75,000lb. This is off the top of my head. I'll check later today If your going to Mig this use a flux core wire with 100% Arigon gas not Co2 or C-25 gas. If it were me I would Tig it with a flux core brazing rod. If your going to stick weld Ark weld, use a 6010 and follow over with a 7018. The Tig would be the most ideal due to heat. Heat will bend, it's the nature of the beast!

Got it! What you are looking for is (A-106-B) seemless tubing! This is what is used for building drilling rig derricks. This is what you want.

ASTM A106 Carbon Steel Pipe & Tube
S/A 106 seamless pipe is one of our most popular products. We carry Schedules 10 through 160, STD, XH, and XXH.

A106 Pipe
ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless carbon steel pipe for high-temperature service.

Federal Steel Supply is a world leader in the supply of A106 / SA 106 pipe and stocks a full range of grades B/C in a size rage of NPS 1/8" to NPS 48", with nominal (average) wall thickness as given in ANSI B36.10. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification*. Pipe ordered under this specification shall be suitable for bending, for flanging, for welding, and for similar forming operations. A full range of A106 stock is available in Schedules 10 through 160, STD, XS, XXS. Unscheduled wall thicknesses available up to 4 inches.

Friends, many thanks for the tips and information. I'll analyze everything. There is still a small prproblem. Not every steel can be obtained in Russia. And I'm looking for steel that I can weld in a garage. I have no conditions for welding alloyed carbon steels. After they are welded, it is necessary to remove the stresses of the seam. This requires an oven. Most likely for the frame I will use steel 20. In America it is 1020. This welding is unlimited and not prone to hardening. But for a fork it will not work. Not enough elasticity. I'm afraid this will bend under the load. Probably 30 HGSA steel suitable. I do not know the American analog. In America, the steel 4130 is an analog of the Russian 30 hms.
