Abstract
The main purpose of this study was to develop a portable electronic tack welding device and determine its tacking time duration, power consumption and tacking operation. This was based from the principles of resistance spot welding with the purpose of joining sheet metals by fusing through resistance heating on tacking operation. This study employed developmental method of research wherein an innovation was made in a spot welding. The data were gathered using actual experimentation and evaluation sheet. The device was evaluated by Forty (40) evaluators including twenty (20) professors in the academe and twenty (20) experts in the field of electrical, automotive and metal craft industry. This study was limited to the development of the portable electronic tack welding device intended for fusing steel sheets ranging from gauge # 21 to gauge # 25. The parameters measured were the tacking duration, the power consumption and the fused result of the tacking operation on varied steel sheet thickness and will undergo in three (3) trials of testing. The level of acceptability was evaluated in terms of its design, composition and operating performance. The study showed that the tacking duration of the device showed that as the gauge thickness increased the slower is the tacking time however there was an increased in the power consumption. Likewise, the device was able to fuse together the given thickness of steel sheets after the tacking operation. The device was also evaluated its overall acceptability in terms of design, composition and operating performance as “very acceptable”.
