Welding is a critical construction-related activity generally used for binding materials together through heat application. It is a fabrication process that involves the usage of heat, pressure, or both to fuse two parts. This study focuses on the creation of welding chambers to improve performance, safeguard the welder's health, and provide a safety preview while doing welding procedures. The model that is being discussed consists of four (4) major parts; the welding chamber is made of wood-based heat-insulating wall and fiberglass to protect the welder from exposure to the welding arc. The three-way
modular fixture table has a swivel base to move in a circular motion for easy use, front- to-back linear movement, and a tilting mechanism. The air ventilation system consists of
an activated carbon filter for the odor, fume removal with a high-density primary filter for large debris, a HEPA filter for the finer particles, and two exhaust fans are all included in the fume filter. The components are all positioned above the table with a hydraulic jack and are supported by telescopic square tube guides that allow height adjustment. The prototype tested the performance of the user's and its safety by scanning the average temperature of fiberglass, inner and outer walls, which shows that the average temperature of 3 parts was safe for the user's touch temperature. The allowable materials inside of the chamber are 550 mm x 550 mm x 250 mm and 25 kg for the weight. The prototype was evaluated by 30 respondents, students who are knowledgeable and have experience in welding, and was rated 4.35, with a very good descriptive rating. The prototype was successful in its entire operation; however, it only reduced the human work freedom of movement since the glove ports are too small to insert the user's arm.
