Ernie A. Daitao, D.I.T.

Abstract
This developmental study was conducted to design, fabricate, and evaluate the new features of the Multi-Angle Welding Jig (MAWJ) so that can easily set, securely and automatically clamp and releases workpieces allowing high degree freedom of movement, fast and accurate welding procedure. Specifically, this study focused on the clamping performance of the device in holding different sizes and shapes of the pipes and bars driven by 15 psi pneumatic pressure connected to a compressor. Then, the study also focused on the adjustable clamps and jaws that adjusted could be adjusted in multiple angles of 30°, 45°, 60°, 90°, and 180°. Moreover, the data recorded concerning time showed that the device was quick in clamping and releasing and when the user applied to weld or tacking it can finish the whole process in seconds.
