Projection Welding Handbook. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases. Projection welding Las proyeksi dilakukan dengan menghubungkan dua benda kerja yang akan disambung pada dua elektroda dan menggerakkannya secara perlahan.
When projection welding high impact will damage the projection before welding and result in poor projection welds even when all other settings are correct. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. The current and the heat generation are localized by the shape of the workpieces either with their natural shape or with specially.
In addition to a chapter on friction welding a new chapter introduces friction stir welding the process that has users excited about the significant advantages it offers.
Ketika kedua benda kerja tersebut hampir bersentuhan terjadilah loncatan arus listrik yang mengakibatkan. Projection welding is a variation of resistance welding in which current flow is concentrated at the point of contact with a local geometric extension of one or both of the parts being welded. When projection welding high impact will damage the projection before welding and result in poor projection welds even when all other settings are correct. Brackets spigots and weld nuts to sheet metal where there is access from only one side and for making attachments to solid forged or machined parts.
