Development of welding auxiliary equipment for upper limb disabilities

Abstract

This study aimed at the realization of the CO2 gas shielded arc welding auxiliary equipment for both-upper limb disabilities.

This auxiliary equipment realized a sole operation type and a knee clip operation type to give response for variety of input.

Appearance tests and bending tests were conducted on test specimens after CO2 gas shielded arc welding using the realized auxiliary equipment. In the appearance tests, the knee clip operation type was passed to criteria of the qualification test of welding technicians. By contrast, the sole operation type was not passed to criteria of the qualification test of welding technicians. Both operation types failed to pass the strength criterions in the bending tests. This is due to the lack of weaving motion, which is essential for welding. In the future, the auxiliary equipment improve to allow weaving motion.
