Ascent's traveling laser-welding robot minimizes the heat-affected zone
and does not introduce high thermal loads into the structure.
By removing ions from the surface, electropolishing is effective in removing the outer skin of metal, containing the discoloration in the heat-affected zone
This combined depth is called the heat-affected zone
and it actually can be measured under magnification.
For instance, the heat-affected zone
(HAZ) is significantly smaller; at only micrometers across, the HAZ of the welding process does not affect nearby sensitive components.
Also, the HFW process has much better control over weld and heat-affected zone
(HAZ) hardness, often causes attributed to pipeline failure.
Among the topics are inertia friction welding for aerospace applications, hybrid laser-arc welding of aerospace and other materials, heat-affected zone
cracking in welded nickel superalloys, quality control and non-destructive testing of self-piercing riveted joints in aerospace and other applications, composite-to-metal bonding, and high-temperature brazing.
HAZ heat-affected zone
in our case was determined till 0.
The microstructure of heat affected zone as shown in Figure 5, while the heat-affected zone
can clearly see the martensite appears.
The result of this is a small heat-affected zone
(HAZ), which cools very rapidly with very little distortion, and a high depth-to-width ratio for the fusion zone .
The finer plasma cuts produce a minimal heat-affected zone
, further enhancing cut quality.
What we found out, in the old days 30-40 years ago, EDM would leave anywhere from two to six thousands thickness of heat-affected zone
[HAZ] that would contain micro-cracks, recast layer and annealed laver," Kiszonas notes.
Special attention in development of the ESC technological process with melting together is paid to achievement of the required metal properties in the area of connection, including heat-affected zone
of metal of the part being melted together.
