Comprehensive simulation of adjustable welding jig through ASIE model in refrigeration and air conditioning workshop

Welding job involves a number of different tools and it is very common to use welding jigs on a project due to their strength and dependability. However, most of the welders used only brick, cast iron or G clamp for welding purposes that can be very risky and ineffective as the welding workpiece needs to be tightly secured because welding work can be very dangerous if the workpiece falls, despite the lowering of the welding accuracy. Thus, the objectives of this study are to design and develop a simulation for adjustable welding jigs through ASIE model application in refrigeration and air conditioning workshop and test its functionality using the Technology Acceptance Model (TAM). The design and development process through the ASIE model consists of four phases, namely analysis, strategy, implementation and evaluation. This study used a design and development (DDR) research design that involved quantitative data in which the experts in the welding industry assess the product’s functionality through questionnaires. The population and sampling were selected randomly through the purposive sampling method in order to determine the respondents of the study. Overall, the documented experts’ evaluation explains the strengths and advantages in the design of the product. In addition, these adjustable welding jigs have made welding jobs easier, quicker, more accurate, comfortable and cost-efficient.
