Which cutting method combines water and abrasives to cut metals that cannot tolerate heating?

• A. Water Jets
• B. Plasma Cutter
• C. Laser Cutting
• D. Oxyacetylene Torch

Answer: (A)

Water jet cutting uses a high-pressure stream of water, often with an abrasive added, to physically erode the material rather than melt or burn it. Because the process doesn’t rely on heat, there’s essentially no heat-affected zone, which keeps heat-sensitive metals from warping or changing properties. That makes it the best choice for metals that can’t tolerate heating. In contrast, plasma cutting, laser cutting, and oxyacetylene torch depend on high temperatures to cut, which can melt, warp, or alter the material.
