What is Butt-Welding or Upset Welding?

Butt-welding is a technique where two metal ends are connected with no overlap, forming a near seamless merger. To do so, the two ends are heated by passing an electric current through the weld interface. The interface causes heating due to resistance to the current. Heating continues until the metal reaches a plastic-like state. The ends (or butts) are then pressed together, where they form a knot or upset. The knot or upset is then ground down to a smooth finish. This technique is great for creating closed-loop steel rings or welding rods. Butt-welding is sometimes used interchangeably with Upset Welding. As we can see both of them are the exact same process with just a difference in the name.

Annealing-Post Weld Heat Treatment (PWHT):

Heat-treatment post welding involves, changing the properties of metals such as carbon steel or alloy steel by processes involving heating. It is used to harden, soften, or modify other properties of materials that have different crystal structures at low and high temperatures. The type of transformation depends on the temperature that the material is heated to, how fast it is heated, how long it is kept heated, what temperature it is first cooled to, and how fast it is cooled. For example, quenching hardens steel by heating it to high temperatures and then quickly immersing it in room temperature oil, water, or salt brine to prevent carbon atoms from moving through the crystal structure and forming carbides, which soften the metal. The two main approaches to softening a metal (to restore its ductility) are annealing, in which its temperature is slowly raised, held for some time, and slowly cooled, and tempering, in which it is slowly heated in an oil bath and held for some hours.

Heat treatment following welding may be carried out for one or more of three fundamental reasons:

-To achieve dimensional stability in order to maintain tolerances during machining operations.

-To produce specific metallurgical structures in order to achieve the required mechanical properties.

-To reduce the risk of in-service problems such as stress corrosion or brittle fracture by reducing the residual stress in the welded component.

What is Annealing:

Annealing is a heat treatment process which alters the microstructure of a material to change its mechanical or electrical properties. Typically, in steels, annealing is used to reduce hardness, increase ductility and help eliminate internal stresses. This consists of heating a metal to a high temperature, where recrystallisation and/or a phase transformation take place, and then cooling slowly. This is often carried out to soften the metal after it has been hardened, for example by cold working; a full anneal giving the very softest of microstructures. It also results in a reduction in both the yield and the tensile strength and, in the case of ferritic steels, usually a reduction in toughness.One of the main applications of annealing is reversing the effects of work hardening. Besides steels, other metals may also benefit from annealing such as copper, aluminium and brass. For steels, subcritical annealing takes place at 540°C - 640°C (1000°F – 1200°F), so there is no crystal structure change. Intermediate annealing is carried out at 640°C - 760°C (1200°F – 1400°F), so there is some transformation to austenite and full annealing involves completely austenitizing the work at 815°C - 925°C (1500°F – 1700°F).

Why is Stress Relief required post-welding:

Welding involves the deposition of molten metal between two essentially cold parent metal faces. As the joint cools the weld metal contracts but is restrained by the cold metal on either side; the residual stress in the joint therefore increases as the temperature falls. To reduce this high level of residual stress, the component is reheated to a sufficiently high temperature. As the temperature is increased the proof strength falls, allowing deformation to occur and residual stress to decrease until an acceptable level is reached. The component would be held at this temperature (soaked) for a period of time until a stable condition is reached and then cooled back to room temperature. The residual stress remaining in the joint is equal to the proof strength at the soak temperature.

How does Stress Relief work via Post Weld Heat Treatment?

Stress relieving is a technique to remove or reduce the internal stresses in a metal. These stresses may be caused by a number of reasons, ranging from cold working to non-uniform cooling after forging. Stress relieving is usually accomplished by heating a metal below the lower critical temperature and then cooling uniformly. It relies upon the fact that, as the temperature of the metal is raised, the yield strength decreases, allowing the residual stresses to be redistributed by creep of the weld and parent metal. The high residual stresses locked into a welded joint may cause deformation outside acceptable dimensions to occur when the item is machined or when it enters service. High residual stresses in carbon and low alloy steels can increase the risk of brittle fracture by providing a driving force for crack propagation.
