How does welding affect the life of a steel spring?

The steel is typically through-hardened by heat treatment and the springs are often shot-peened to improve fatigue life. Both of these effects are reduced near the weld by the heat of welding. If a spring broke then it broke at a high stress location.

What is heat treating spring steel?

Heat treating spring steel produces the most effective elastic limit along with best fatigue properties. The surface conditions should be sound and smooth. Corrosion and decarburisation are very detrimental to fatigue strength of steel springs. Removal of the decarburised layer increases the fatigue limits.

How can I improve the mechanical properties of a spring steel?

You need a spring steel for your application so you can improve the mechanical properties by heat treatment. However material selection is subject to its service conditions ie enviroment, frequency of operation, forces etc. expected forces at given deflections and spring rate.

How do you heat treat mild steel?

Hi Ankeet18. The only heat treatments you can do on Mild Steel is anneal, normalize or stress relieve you cannot harden and temper it. which is probably what your thinking of to get your spring.

Can u weld spring steel?

Springsteel is a high carbon, heat treated steel which is impossible, or at least very difficult, to weld. Even if you could weld it, the heat generated by the weld would normalize the welded and heat affected zones and the springing properties would disappear.

Can you weld springs back together?

Our answer is always no. You shouldn't even weld near your springs, let alone on them. Springs don't stand well to heat, since heat causes springs steel to de-carbonize and lose tensile strength, making the area around the weld brittle like a cheap pencil.

Can I weld a broken spring?

As we stated earlier, it is not recommended that you attempt to weld a broken leaf spring. The biggest factor is that heat generated during welding can weaken the tensile strength of the steel. While welding can be performed in some instances, most mechanics will recommend against it.

How do you make spring steel?

Spring steel's high yield strength is achieved through one of two manufacturing processes: (1) Hardening by heat treatment and (2) Work hardening. Hardening by heat treatment is achieved by heating the steel, then quenching it, which rapidly brings it down to room temperature.

CAN 5160 steel be welded?

AISI 5160 alloy steel has poor welding property owing to its high chromium and carbon content. Either arc or gas welding methods can be used to weld the steel.

What kind of metal are leaf springs made of?

steelSprings are mechanical devices that are capable of storing mechanical energy because of their elasticity. Springs are often made of coiled, hardened steel, although non-ferrous metals such as bronze and titanium and even plastic are used.

How thick is 6011 steel?

The steel is about one inch thick, 2 inches wide, and about 3 feet long with a curve in it. It's used for applying anhydrous ammonia, and typically runs in the ground 7 to 12 inches at 6 mph. I veed out the break and made 5 passes with a 6011 on ac. on both sides.

Does welding reduce the fatigue strength of a spring?

Both of these effects are reduced near the weld by the heat of welding. If a spring broke then it broke at a high stress location. A weld can never match the fatigue strength of un-welded base metal, and a weld is not going to last very long at a location with a high cyclical stress range.

What is steel spring made of?

Large tonnages of steel springs are made of carbon steels having carbon from 0.50 to 1.2%. These may be fabricated as- hot-rolled, cold-rolled, or drawn, annealed, hard drawn, tempered, or patented. Choice of material depends on cost, manufacturing method, application.

What is spring metal?

Any metal, or alloy which can be hard drawn, or rolled to fairly high strength and retains sufficient ductility to form, may be used for springs, or any alloy which can be heat treated to high strength and good ductility before, or after forming may be used. For special spring properties such as good fatigue life, non­magnetic characteristics, resistance to corrosion, elevated temperatures and drift require special considerations.

What is the physical constant of springs?

One physical constant that enters into design of all spring elements is the elastic modulus, or load-deflection ratio (Table 12.7). Metals differ widely in stiffness, the tension modulus ranging from 41.4 GNm -2 for magnesium to 517.5 GNm -2 for iridium.

How is carbon steel hardened?

The high carbon steel (Table 12.8) is hardened by quenching in oil and tempering in a lead bath. Tempered wire is used largely for springs up to 12.5 mm diameter wire. It is then coiled. These are general purpose all types of coil springs when stresses are not too higher (> 552 MNm -2 ). Some other high carbon springs are made as given in Table 12.9.

What factors determine the maximum safe stress for springs?

The factors governing the maximum safe stress for springs are the elastic limit, or proportional limit in tension, and the torsional proportional limit. Loading to greater stress values would result in permanent set and the spring would not return to its original state. ADVERTISEMENTS:

Why is stainless steel important?

Stainless steels have gained importance for springs working at high temperatures and under corrosive conditions due to their higher heat resistance to loss of strength, and to surface oxidation.

Why do springs fail?

Fatigue is most common cause of spring failure due to some stress raiser, or heterogeneity.

How to make spring out of mild steel?

What material was used to make wire cutters?

If you read the book "Stalag Luft 13", (I think, going from over 40 year old memory, the book on which the movie, "The great escape" starring Steve McQueen was based,) you will find a passage where it describes that to make wire cutters, they would take mild steel strap material, which was left over from the camp's construction, and which they could scrounge, (how I don't remember) and heat it red hot, and quickly plunge it into a bucket of pure sugar.

Is a spring a convential spring?

I understand that your spring is a shaped spring from flat material and is not like a convential spring however it still must have a spring stiffness. At what point along the arms is the load applied to the spring as this will affect the spring rate, stress in the spring and spring deflection.

Can heat treatment change bending stiffness?

What cory said. You cant significantly change bending stiffness using heattreat or mechanical work, even alloying will have little effect until the alloy content gets large.

Does corrosion sleep?

Corrosion never sleeps, but it can be managed.
