Pressure Welding and Arc Welding both involve joining metals but differ in technique and application. Pressure Welding uses applied pressure to join materials without filler material, ideal for pressure vessels and pipelines. Arc Welding employs an electric arc to melt metals, suitable for diverse fabrication tasks. Understanding these differences helps in selecting the right welding method for specific projects.
