Final answer:
The torch should be held at an angle range of 15 to 45 degrees during forehand welding to ensure proper weld penetration and bead shape, while wearing safety gear to protect from thermal energy and electric arc.
Step-by-step explanation:
When performing forehand welding, the proper technique involves holding the torch at an angle range typically between 15 and 45 degrees to the workpiece. The angle is crucial as it affects the penetration and bead shape of your weld. If the angle is too steep, it can lead to a number of welding defects, including excessive penetration or undercutting. Conversely, too shallow an angle can result in insufficient penetration and a weak weld. Maintaining a consistent angle throughout your weld will contribute to the strength and appearance of the final weldment.
It is important to wear the appropriate safety gear, which includes welder's gloves and a helmet. These protect the welder from the intense thermal energy and electric arc that come with welding. The electric arc not only melts the rod but is also capable of spraying sparks and emitting high-energy electromagnetic radiation that can cause severe damage to the skin and eyes.
