Visual inspection revealed a spot weld
had failed on the muffler body where the shroud support flange is attached.
In the spot weld
of TRIP1100 steel, the HAZ is divided into three subzones from a metallurgical viewpoint: uppercritical (UCHAZ), inter-critical (ICHAZ), and sub-critical HAZ (SCHAZ).
Characterization of spot weld
growth on dissimilar joints with different thicknesses.
Some information is available from [1, 2] and the literature [3, 4] give general information on spot weld
process as well as the advantages of using spot weld
compared with the most common joining techniques.
The main feature of the method is simultaneous evaluation of spot weld
fracture and edge fracture with a simple test specimen and test equipment.
where [F.sub.n] and [F.sub.s] are the applied normal and shear loads, respectively, [F.sub.N] and [F.sub.S] are the normal and shear failure loads of the spot weld
, respectively, and n is the fitting parameter.
Design data was ported directly to robot welding machines at the Bootle factory that position and spot weld
each reinforcing bar onto steel tapes to create a carpet with each bar precisely located.
Then, the researchers fired the beam of the electron microscope to spot weld
the tube between the tips of two tungsten needles.
Key words: least-squares; nondestructive analysis; spot weld
; transducer; two-dimensional; ultrasonic
Today it's cheaper to laser weld than spot weld
. But because bean-counters here run the numbers so hard, engineers fear new technology."
This is known as spot weld
. Achieving a consistent spot weld
eliminates variances in your sight picture, which equates to more consistency in your shooting.
To this end, the sounds of three arc, gas metal arc and spot weld
machines were transferred to a computer during welding process via a microphone and recorded separately and then, by applying FFT, discrete frequency components were ascertained.
