The practice of uniting metal parts by heating or compression is called:

  1. arc

  2. bead

  3. tensile strength

  4. welding

The correct answer is: welding

Welding is the process of joining metal parts by heating or compression. This involves melting separate pieces of metal and fusing them together. Option A Arc is a welding process that uses an electric current to produce an intense and controllable heat source for welding. Option B: Bead is the material deposited by a welding or brazing process. Option C: Tensile strength is the maximum stress that a material can withstand before failing under tension. While tensile strength is important in welding, it does not refer specifically to the process of joining metal parts. Therefore, option D: welding is the best answer.
