Can steel coils be welded together using arc welding or gas welding methods?

Yes, steel coils can be welded together using both arc welding and gas welding methods. Arc welding, specifically processes like Shielded Metal Arc Welding (SMAW) and Gas Metal Arc Welding (GMAW), is commonly used for joining steel due to its strength and versatility. Gas welding, which uses a fuel gas and an oxygen mixture to produce a flame, is also suitable for steel welding, although it may be less common in industrial settings due to the higher heat input and potential for distortion. Proper techniques and equipment are essential to ensure a strong, durable weld and to avoid defects such as cracking or warping.
