Abstract
This paper describes and develops the concept of adapting the chemical oxygen iodine laser (COIL) system for aluminum welding. The suitability of the COIL for welding aluminum or Al-SiX alloys, such as A40 is evaluated using current welding material processing techniques. The problem of high thermal conductivity coupled with the high reflectivity of aluminum, which makes it difficult to laser weld, is addressed by proposing the use of a mathematical model for laser welding. The model should predict the size of a laser weld to the net heat absorbed by the workpiece. Thus, the problem of excessive heat flow to components is addressed. The possibility of utilizing the high output power of the COIL by applying 'binary optics' technology to convert the high power and high quality Gaussian output of the main beam into a set of high quality Gaussian sub-beams which will be transported via fiber optics delivery to the sample surface(s) is also discussed. The COIL is a viable source for future satellite construction which requires hermetic sealing of components and instrumentation.
