In the visual inspection, throat thickness of fillet welds
The FSW process has been used to make welds
in aluminum up to 3-inch (76.
The typical measured bead sizes of welded
automotive components such as air intake manifolds are in the range of 3-4 mm, and are similar to the bead sizes observed in research butt welds
Figure 2 shows the scanning electron micrographs of the fractured tensile test specimens of the weld
, laid out with the same parameters, using the developed as well as the parent acidic flux.
In most cases, tensile tests were performed on the welds
On the other hand, this technology introduces special preparation of the welds
as well as their positioning during the welding process.
Advanced fully digital power supplies provide precise control of process variables and weld
quality, reducing standard deviation and increasing Cpk index of welding.
total heat input has been decreased by 25 percent while overall mechanical weld
properties have been improved by these systems.
The quality of the welds
would depend on the different welding parameters, from both laser and TIG.
The hybrid laser-arc process could be realized using two different layouts for heat sources, or rather laser source could be the first that welds
the metal (Laser leading hybrid process) or the last one (Arc leading hybrid process).
A NEW, groundbreaking internal weld
inspection system has been launched that inspects the internal size and shape of girth welds
on pipes that are destined for use in deep sea subsea oil and gas applications.
Adding GMAW to the welding mix also enhances a finished part's metallurgical stability, and with GMAW's slower cooling rates, produces welds
with greater strength and less brittleness.
Specifically, FEA is being used by processors who encounter problems in achieving successful welds
The structural welds
at the bottom were the biggest I-beams I've ever seen,'' Coronel said.
But then Heinemann cites a study conducted of a hang-on body panel requiring from 30 to 50 welds
