heat-affected zone , HAZ (abbreviation)

No heat-affected zone is produced in the bond between metals.

The cracking occurs in the heat-affected zone of the base material.

The distribution of a0 mirrors the weld and its associated heat-affected zone.

Tool steels should also be preheated to prevent cracking in the heat-affected zone.

There is also a reduced chance of warping the material that is being cut, as laser systems have a small heat-affected zone.

The heat-affected zone (HAZ) is common to all welding processes.

At one exterior surface, a heat-affected zone 0.1mm thick containing unequilibrated alpha(sub)2-kamacite is preserved.

Weld with no heat-affected zone.

It is surrounded by the heat-affected zone, the area that had its microstructure and properties altered by the weld.

Some of the alloys, such as 2024-T4, also have their corrosion resistance lowered in the heat-affected zone if left in the as-welded condition.

A gusset or lug does not reduce the heat-affected zone (HAZ) at the sides and end of the reinforcement.

No heat distortion or heat-affected zones (HAZ).

The combination of fast joining times (on the order of a few seconds), and direct heat input at the weld interface, yields relatively small heat-affected zones.

The addition of scandium to aluminium limits the excessive grain growth that occurs in the heat-affected zone of welded aluminium components.

These include a heat-affected zone of matrix removal and modification and a swelling of the ends of carbon fibres adjecent to the hole.

Also, the ratio of the depth of penetration to the width of the weld is much higher, resulting narrower weld and heat-affected zone.

An important benefit of the water jet is the ability to cut material without interfering with its inherent structure, as there is no heat-affected zone (HAZ).

However, during welding, particularly of small-diameter thin-walled pipe, it is possible for small amounts of sigma phase to be precipitated in the low-temperature heat-affected zone.

Heat-Affected Zone The rapid heating and cooling of the parent metal will affect its structure and this may be deduced from a study of the equilibrium diagrams.

A Model to Describe the Propagation of Cracks in the Heat-Affected Zones of Ferritic Steel Weldments.

The AWS states that for an equivalent carbon content above 0.40% there is a potential for cracking in the heat-affected zone (HAZ) on flame cut edges and welds.

Butting the tube-making it thicker at the ends and thinner in the middle-is an efficient way to strengthen the heat-affected zone (HAZ) at the joints without adding appreciable weight.

The pulses allow the average current to be lower, decreasing the overall heat input and thereby decreasing the size of the weld pool and heat-affected zone while making it possible to weld thin workpieces.

Like electron beam welding (EBW), laser beam welding has high power density (on the order of 1 MW/cm) resulting in small heat-affected zones and high heating and cooling rates.

An undercut crack, also known as a heat-affected zone (HAZ) crack, is a crack that forms a short distance away from the fusion line; it occurs in low alloy and high alloy steel.
