Pre & etch Inspection

We are in the stage to develop the process for Pre-etch and Etch inspection for aerospace industry.

But, we are having trouble to develop the procedure for process and for solution tests.

Can anyone to share me an etch procedure sample? only to follow it as a guide?

All of this, its for etch process prior to FPI.

Any information or recommendation will be welcome.

Thank you.

Rafid,

Have you tried to contact an aircraft manufacturer such as Boeing, Cessna or Learjet? They already have such procedure in place. It would solve your problem and at the same time, it would ensure that you are doing it properly.

Commonly, the acid etch inspection is for Steel and titanium, in this case for us is Inconel (IN100, C101).

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
