Question

Which process in sheet metal is used for producing fluid tight joints?

Answer 1

Resistance Seam Welding

Explanation:

• Resistance seam welding is the process of sheet metal that is used to produce gas- or fluid-tight joints. Examples - making steel drums, steel fuel tanks for motor vehicles, tin cans, etc
• This process depends on welding seams having curvature or are straight welding is not possible on the internal corners
• Welding on both sides of the joint is necessary
• A lap joint configuration is generally needed
• Components that comprise of two half-shells can be welded like petrol tanks
• In an alternate manner, the sheet is to be rolled into tubular form and the longitudinal seam is welded
