gether in gtaw to control heat and shape the weld.
you can start your response with:

• the torch and filler rod work together in

gtaw by...
respond in 2 to 3 complete sentences.

Explanation:

The torch provides controlled heat via an electric arc to melt the base metal, while the filler rod adds material to the molten weld pool. Adjusting the torch's arc intensity and distance regulates heat input to prevent overheating or underheating, and manipulating the filler rod's feed rate and angle shapes the weld bead to the desired contour. Together, they balance heat distribution and material addition for a precise weld.

Answer:

The torch and filler rod work together in GTAW by the torch generating a focused arc to control heat input for melting the base metal, and the filler rod being fed into the molten pool to add material and shape the weld bead. The torch’s position and arc intensity manage heat to avoid defects, while the filler rod’s feed rate and angle determine the weld’s size and contour, ensuring both heat control and proper weld shape.
