Answer:

False.

Step-by-step explanation:

Welding due to the thermal stress caused by the piece and large temperature changes can cause residual stresses in the material due to the efforts that are manifested in it. These efforts can cause microfractures, weakened areas and also a stress and changes in the crystalline structure that does not allow it to maintain the initial properties of the material and be prone to subsequent failures and corrosion.
