This was my first real exhaust fabrication with my side setup, It took me 3 nights after work. I think I had originally said $900 after the work was done (no real quote was given I just said comparable prices to good axle backs which were around $1,200+) and he swindled me down to $600. a friend/acq. 1 / 10.

WebThe end time is the actual end time of the experiment or the start time of the heat exchanger. The mass flow rate increased in proportion to the output of the power supply in each experiment. The T8-4 experiment using 75% output recorded a rate of about 3.5 kg/s. The T8-7 case using 125% output recorded a value of about 5.5 kg/s. Webical cooling time t 8/5, the welding input heat and preheating temperature. The literature [1-11, 16-19] provides 2-D and 3-D models of analytical dependencies. Hence, there is a known rela - tion given by eq. (1) for calculating the cooling time, t 8/5, in function of preheating temperature for the adopted 2-D model: t 2 8/5 22 2 11 4 (500 ...

Webquenched probe gives possibilities for determination of cooling time t8/5 at different distances from the quenched end, for set quenching conditions. In addition, from the conducted end-quenched tests and simulation results, the relation between hardness distribution and the cooling times t8/5 has been established for tested quench conditions. WebWith increasing heat input, the cooling rate decreases (the welding cooliing time between 800 and 500°C, t8/5 and welding cooling time to 100°C, t100 increases) and thus, a risk of the occurence of cold cracking is reduced. Roughly speaking, cold craking is a matter of concern only when heat input is not higher than 3kJ/mm. 5.
