A thermal cutting and welding process involves using heat to either separate (cut) or join (weld) materials, typically metals. Thermal Cutting: This process uses a concentrated heat source (like a flame, electric arc, or laser) to melt, burn, or vaporize a material along a desired line, effectively cutting it into separate pieces. Examples include oxy-fuel cutting, plasma cutting, and laser cutting. Welding: This process uses intense heat to melt the edges of two or more pieces of material, allowing them to fuse together upon cooling, often with the addition of a filler material. The goal is to create a strong, continuous joint. Common welding methods include arc welding (e.g., MIG, TIG, Stick welding) and laser welding.
